I would like to emphasis the speed of publication. Manuscripts arrived during July, the book, including an exhaustive index, was produced July/August and sent to the printers Sept 1st. It must be the most up-to-date volume around because of this short gap between submitting and printing! If you are interested in this (and in the previous two which are still available at a knock down price) please let me or preferably Dr Barbara Evans know. She will give you details of cost postage and packing etc. Barbara is: sabjbe@cf.ac.uk We should be able to dispatch these as soon as orders arrive at the beginning of October.

This may not be the perfect forum and the right way to put forward this issue, nevertheless, an effective one and I must also inform that I had obtained permission from the moderator for writing a mail like this long time back (hence I am not doing anything illegal). I am looking for a post-doc position in the area of biofilm modeling, simulation coupled with experimental work. I have a MS in Physics, and am close to the completion of Ph.D. in Chemical Engineering. I would also have completed 32 credits of course work in Computer Science by May '98 which I believe can come in handy for the type of work I do. The following are the list of my publications: 1) Heat and mass transfer simulation studies for solid state fermentation, Chemical Engineering Science, 49, 2187-2193, 1994. 2) Evaluation of relative growth limitation due to depletion of glucose and oxygen during fungal growth on a spherical solid particle, Chemical Engineering Science, 50, 803-811, 1995. 3) Modeling of heat and mass transfer for solid-state fermentation process in a tray bioreactor, Bioprocess Engineering, 13, 161-169, 1995. 4) On the reduction in the moisture measuring time of dried lignite, Energy Conversion and Management, 38, 697-699, 1997. 5) Modeling solid particle degradation by Bacillus coagulans biofilm, Bioresource Technology, In press. ------------------------------------------------------------------- Please write to me if you are interested.

This meeting has traditionally been the best international forum for microbial ecology since its inception 20 years ago in New Zealand. I would like to encourage as many submissions of abstracts as possible from indivduals doing research with biofilms or other exciting aspects of microbial ecology. With respect to biofilms, D.C. White will be giving a plenary lecture on this topic. Bill Costerton and I are organizing a symposium to address the basic biological aspects of biofilms. Topics to be covered here include: biofilm structure and patterns of gene expression (likely D. Korber), gene transfer within biofilms (to be confirmed), role of quorum sensing genes (homoserine lactone) (J.W. Costerton), effects of starvation-survival and homoserine lactone antagonists (S. Kjelleberg), and biofilm ecology/biomineralization (R.J.C. McLean). Should sufficient abstracts be submitted, we may be able to feature some in an oral session. My hope here is that this oral session will highlight presentations showing new aspects of biofilm ecology. A poster presentation format will also be available. Hope to see you all in Halifax. R.J.C.

The main BIOSCI FAQ (Frequently Asked Questions) is accessible on the World Wide Web at URL http://www.bio.net/. If you can not find an answer to your question in this or other documentation, the BIOSCI technical support staff answers e-mail queries sent to biosci-help@net.bio.net We can only answer questions about the use of the newsgroups and mailing lists. We unfortunately do not have the staff to do Internet information searches or answer scientific questions. Please post those to the appropriate BIOSCI/bionet newsgroups. Contents: -------- 0) BIOSCI NEEDS YOUR SUPPORT!! 1) Using the WWW to access the BIOSCI/bionet newsgroups. 2) What to do about "spams," i.e., junk mail, ads, etc. 3) Examples of subscribing and unsubscribing to the mailing lists. 4) The BIOSCI user address and research interest directory. 0) BIOSCI NEEDS YOUR SUPPORT!! ------------------------------ BIOSCI's government funding has been expended, and we are now operating solely from advertising revenue that we have raised from our Web site at http://www.bio.net/. We need just a few minutes of your time to help us serve you. You can do two important things which will take very little time for you individually and will immensely help us continue to help you. First, please use our WWW system at http://www.bio.net/ to access the archives. You can post or reply to messages via your Web browser as described in item #1 below. Your usage helps attract sponsors. If you contact any of our sponsors, please be sure to thank them for supporting BIOSCI. It is critical for them to get this feedback if they are to continue their sponsorship for the long term. Second, if you work for a company or organization that provides products or services of interest to the biology community, please pass this message on to your marketing or marketing communications department or other appropriate group. Please ask them to help support BIOSCI by sponsoring our Web site and explain the uses and benefits of the system to the biology community. If they are interested, they can then contact us for further information at our tech support address, biosci-help@net.bio.net. 1) Using the WWW to access the BIOSCI/bionet newsgroups. -------------------------------------------------------- As of 10 December 1995, all BIOSCI/bionet full newsgroups are accessible through the World Wide Web (WWW) at URL http://www.bio.net. One can read and reply publicly or privately to both recent postings and archived messages through one's Web browser if it is configured properly to send e-mail. Each newsgroup is equipped with its own WAIS index. The main BIOSCI home page also has access to the BIO-JOURNALS Table of Contents database WAIS index and the BIOSCI user address database described in another item further below. 2) What to do about "spams," i.e., junk mail, ads, etc. ------------------------------------------------------- BIOSCI is a set of parallel USENET newsgroups (the "bionet" groups), mailing lists, and a hypermail archive at URL http://www.bio.net/. The same postings are distributed on all media (except for a small number of mailing-list-only groups at net.bio.net). Unfortunately it is becoming a despicable practice on the Internet (by a few people out to make a fast buck) to do automated mass postings to thousands of newsgroups and mailing lists. These attempts to grab free advertising are refered to as "spams" in the usual, somewhat boneheaded, net terminology. USENET is more susceptible to this practice, and many spams originate on the USENET groups and then are passed on to the mailing lists. However, spammers also get lists of mailing addresses and hit these too, so neither medium is immune. What should you do personally if you get junk mail? --------------------------------------------------- Just delete it and move on without reading it further. Filing a protest is becoming increasingly useless because spammers are often disguising the addresses where the messages are sent from. Unless you really understand Internet mail systems, your attempt at protest by sending replies to the message will often end up being sent to the address of an innocent person that the spammer is victimizing. What can BIOSCI/bionet do to protect its newsgroups? ---------------------------------------------------- The only solution currently available is to moderate the newsgroup. If this newsgroup is already moderated, then you are in good shape. Moderation protects the USENET distribution from about 95% of the spams that are being sent to date and protects the mailing lists completely. Moderation means, however, that someone has to take the time to review each message before it goes out. We have set up software here that simply allows the moderator to forward to an address at net.bio.net messages that (s)he wishes to have distributed. This takes no more time than that needed to read the message and pass it on, say about 1 min. per message. Most newsgroups currently have a discussion leader who is responsible for their newsgroup. The discussions leaders and their e-mail addresses are listed in the BIOSCI Information Sheet which is available on the Web at http://www.bio.net/. If a newsgroup is being hit with too many junk postings, please contact the discussion leader for that group and see if there is interest in moderating the group. Please do not assume that by simply posting a complaint to the newsgroup itself, anyone on the BIOSCI staff will act on your complaint. With close to 100 newsgroups to run, the BIOSCI staff has to rely on the discussion leaders of each newsgroup to report problems directly to us at biosci-help@net.bio.net. We will moderate any of our newsgroups if the discussion leader tells us that the readership of the group wishes to do so and if a moderator is willing to do the work. For most BIOSCI/bionet groups, this entails only a few minutes of work each day. Moderating a newsgroup will resolve probably 95% of the junk postings on the USENET distribution. Unfortunately there are easy ways for determined spammers to override the moderation mechanism on USENET, but we can protect our e-mail subscribers from unwanted postings if the newsgroup is moderated. You can also access our newsgroups over the WWW at URL http://www.bio.net. While this Web interface will not stop spammers from trying to post to the groups, this will give you yet another way, besides using USENET news, to keep the junk out of your personal mail files. For those of you with local USENET news systems, the Web interface will also give you faster access to new newsgroups and recent postings. 3) Examples of subscribing and unsubscribing to the mailing lists. ------------------------------------------------------------------ PLEASE NOTE: The BIOSCI management does NOT act on subscription/unsubscription requests that are posted improperly to the newsgroups and mailing lists. People who do this only bother everyone on the lists to no avail. Please be sure to follow the proper procedures below. Gory details are in the BIOSCI Information sheets on the Web at http://www.bio.net. Below we give an example utilizing the METHODS-AND-REAGENTS list at both of our two BIOSCI sites: Users in the Americas and Pacific Rim countries who use the BIOSCI ------------------------------------------------------------------ node at computer net.bio.net: ---------------------------- A) Determine the "listname" which is the <=8 character mail address ^^^^^^^^^^^^^ for the group. These can be found in the BIOSCI Info. Sheet. For the METHODS-AND-REAGENTS group the mailing address is methods@net.bio.net. The listname is the portion of the address to the left of the @ sign, i.e., "methods". The listname is used with the "subscribe" and "unsubscribe" commands illustrated below. B) Mail all commands in the body of a mail message addressed to biosci-server@net.bio.net. Do NOT send commands to the newsgroup posting addresses! Leave the Subject: line blank, any text on it will be ignored. C) In the body of your message put one or more of the following commands with an "end" command on the last line, e.g., subscribe methods unsubscribe methods end Do NOT put your e-mail address or other text on these lines. The server only allows you to cancel your subscription if the address on your mail header matches the address on our mailing list. Please ask for help at biosci-help@net.bio.net if your address has changed, e.g., if you know you are on the list but the server tells you that you are not a member. Users in Europe, Africa, and Central Asia who use the BIOSCI node at -------------------------------------------------------------------- computer daresbury.ac.uk (also known as dl.ac.uk): ------------------------------------------------- To subscribe and unsubscribe to/from the BIOSCI lists, you need to specify the full USENET newsgroup name with "bionet-news." prepended. The USENET newsgroup names are listed in the BIOSCI Information sheet on the Web at http://www.bio.net/. For the METHODS-AND-REAGENTS list the USENET newsgroup name is bionet.molbio.methds-reagnts, thus the appropriate commands are sub bionet-news.bionet.molbio.methds-reagnts unsub bionet-news.bionet.molbio.methds-reagnts These commands are included in a message addressed to mxt@dl.ac.uk, NOT to the newsgroup mailing addresses. As usual, include the text in the body of the message as text on the Subject: line is ignored. To unsubscribe from all the lists at the UK node, use unsub bionet-news Please note that if the address in the list is different than the one in your mail message header, you will not be able to unsubscribe by this method. If you have problems, please mail biosci@daresbury.ac.uk. 4) The BIOSCI user address and research interest directory. ----------------------------------------------------------- Please take this opportunity to add your name, address, and research interest information to the BIOSCI User Address Database if you have not already done so. You can fill out the address form directly through our Web page at URL http://www.bio.net/adrform.html. The address database is reindexed nightly for WWW access (the URL is http://www.bio.net/). If you are not directly on the Internet but can reach it by e-mail, please use our waismail server to access the user directory. waismail use is described above. You can also request a user address form by e-mail from biosci-help@net.bio.net. Please check your database entry from time-to-time to see if your address information is still up-to-date. Because of our limited personnel resources, we ask that you resubmit a *complete* form to revise your entry; we only replace complete entries and do not have resources to edit old forms.

The moderation will be taken care of by myself, Rob Palmer and Bob McLean. We will take turns, 4 months each. You should not notice any difference except that you shouldn't be bothered any more by all the trash mail we have seen the last few months. I am sorry that the policy change wasn't effective earlier, but I had little to say in that respect. However, the rules are still the same. I enclose below the modified charter for the newsgroup. You can still post messages by using usenet software or e-mail (to biofilms@net.bio.net). We will attach a small tail on all postings which direct you to a web page containing 1) subscription info, 2) contact addresses and, most important 3) a Web resource with references to networked sources of information on biofilms - WE NEED YOUR INPUT HERE TO GET IT RUNNING! Please send me (or the other moderators) info on any internet resource you may know concerned with biofilms, then we can include it in the webpages. (note the webpages are not quite done yet, but check out http://www.im.dtu.dk/biofilms). I hope there will be no inconvenience to you because of this change. If so, please don't hesitate to e-mail me (cs@im.dtu.dk). Best regards, Claus Sternberg -------------- revisd newsgroup charter ------------------------ Information for BIOFILMS/bionet.microbiology.biofilms USENET newsgroup name: bionet.microbiology.biofilms Status: Moderated One line Description: Research on microbial biofilms Moderation address: bionet-microbiology-biofilms@net.bio.net (biofilms-moderator@net.bio.net is an alias for bionet-microbiology-biofilms@net.bio.net) Moderator: Claus Sternberg Department of Microbiology Technical University of Denmark Co-moderators: Bob McLean Department of Biology Southwest Texas State University, Texas Robert J. Palmer, Jr. Institute For Applied Microbiology University of Knoxville, Tensessee. Mailing list name: BIOFILMS e-mail addresses: biofilms@net.bio.net biofilms@daresbury.ac.uk Newsgroup character: Definition of microbial biofilms: Microbial biofilms are layers (sometimes only one) of microorganisms associated with a surface of some kind. The organisms in a biofilm may be a single species or multiple species. The organisms may for example be bacteria, yeasts or protozoans, or combinations. The surfaces may be solid surfaces such as metals, glass, plastics, or dentin, or may be less well defined, such as soil particles, or plant tissue surfaces. The association to the surfaces may be tight, by direct binding, or loose, such as cells residing in gelatinous matrices. bionet.microbiology.biofilms is a forum for scientific discussions/questions regarding all aspects of the science related to microbial biofilms, including but not limited to biofilm initial events, formation, maintenance and breakdown, genetic and physiological aspects of microorganisms in biofilms or organisms isolated from biofilms, role of biofilms in pathogenesis, in industrial applications, and as a tool in teaching. The Biofilms newsgroup will provide: A forum to discuss concepts, problems and recent developments in the field of microbial biofilms. A forum to discuss development of laboratory systems for growing, inspecting and in-depth analysis of microbial biofilms. A forum to discuss the role of biofilm science in education. A bulletin board for announcements of meetings, funding sources and job opportunities. A communication source for sharing mutants, strains, molecular probes, etc. Opportunities for collaborative efforts between labs at different locations and/or between industrial and academic research labs. The forum will also provide opportunities to exchange new ideas concerning the teaching of microbiology, and curricular design, as well as the education of the public about the benefits and/or hazards of microbial biofilms. A list of frequently asked questions (FAQ) concerning microbial biofilms should be created with the joint efforts of the newsgroup members, and kept in an electronic form accessible for anyone. A list of pointers to other interesting related resources in the form of a world-wide-web page (http://www.im.dtu.dk/biofilms/). Further remarks: The newsgroup encourages the participation of both academic and industrial affiliated individuals or organizations, and anyone else with an interest in microbial biofilms. Discussions should as a general rule be conducted in the newsgroup, rather than being continued by private e-mail. Only when discussions take a personal turn which obviously is of interest only to the persons involved, it should proceed privately by e-mail. General questions about confocal microscopy: Confocal microscopy is an important tool for many people working in the biofilm field, but technical questions concerning this technique of microscopy should be directed to the newsgroup on this topic (bit.listserv.confocal; Send an e-mail to listserv@listserv.buffalo.edu with the message (ignore subject): subscribe confocal "Your Name"). Moderation Policy: Mass-posted commercial messages, chain letters, and similar postings not germane to microbial biofilms will be deleted without comment. Inappropriate messages posted in good faith will be returned to the sender. Messages not strictly within the charter but likely to be of interest to many subscribers will be accepted. Use of the newsgroup for commercial purposes is prohibited.

Typically anionic bacterial cell surfaces bind Fe quite well, however the iron will dissociate in the presence of H+ ions (i.e. low pH) generally below pH 5. Alternatively, Fe flocs can be dissolved if the mixture is subjected to reducing conditions. A few years ago, I did a study on this phenomenon. The journal citation is: R.J.C. McLean, D.

The clusters were approx 200 microns diameter. We estimated the volume of the clusters by assuming they were hemispheres. We got about 1x10^10 cells / ml of cluster material. The cells were gram -ve rods 2 microns long by 1 micron wide to give a vol of 1.31 microns cubed. This works out that the vol occupied by cells in a cluster is 1.31 %. Some of this is written up in Stoodley, P., de Beer, D., and Lewandowski, Z. 1994. "Liquid flow in biofilm systems." Applied and Environ. Microbiology. 60:2711-2716.
