If a steady state is achieved with little or no change in the external environment (going back to deep terrestrial here) genetic exchange will no doubt occur between bacteria - potentially causing genetic convergence between unrelated species? Just a few questions/thoughts to ponder on! Thanks for your time and I hope somebody can help.

They are still looking at the organisation of biofilms deep in the basalt under the former Hanford nuclear development site. These grow as a result of groundwater interaction with the rock, which releases hydrogen as the primary energy source, with subsequent secondary growth on the organics so produced. There are a number of others working on such sub-surface biogeochemistry, including Joe Suflita on SRBs etc. There are many other primary examples. One of the problems in getting an answer to your question might be your limitation to freshwater. In terms of really mature biofilms you cannot get past some of the streamers formed in acid mine drainage. There are classic examples in the UK eg Wales. The person to contact is Barrie Johnson at Bangor. These streamers can be metres long, perhaps a metre wide and thickness measured in (I'm guessing) a few centimetres. These represent a fascinating biogeochemical cycle where the top layers are red - due to aerobic oxidation, and precipitation, of iron at acid pH (high sulphate) - the middle sections are "colourless" - and the bottom sections are black, due to anaerobic oxidation of said sulphate to H2S, with precipitation of black metal deposits at neutral pH. Barrie is pretty well versed on the phylogeny of these species, including tracing back to common ancestors. But I think you'll find that between aerobic and acidophilic iron and sulphur oxidisers on the one hand, and anaerobic and neutrophilic iron and sulphate reducers on the other there ain't much in the way of genetic convergence! Something very similar happens at hydrothermal vents at black smoker chimneys. Here the matrix is seawater, though what is bubbling out is geothermal. The exact same situation arises as per above, except you have thermophilic sulphur oxidisers providing primary resources to mesophilic and marine SRBs in the space of nanometres, and within the concretions of the chimneys. I would be guessing that freshwater systems per se are probably too oligotrophic to support anything close to either example of a mature biofilm (though the chimneys are hard to classify given their concretions).

I'm from White's lab, so I know his work. There are other methods besides his, such as molecular biology and microscopy. Let me know of any information you get from them. > Also, suppose you obtain a number of closely related > species/strains from an established biofilm (eg. borehole/deep > terrestial), what are the chances of these strains having a > common evolutionary progenitor? Recently? Not likely. You are asking about strains you have isolated. Bacteria in deep boreholes do not have a high reproduction rate. The ones you cultured were just alive enough for you to culture them. Given different ideas of what an organism would want, different organisms might be cultured. If you had cultured the deep sub-surface samples under 80% N2, 10% CO2, 10% H2, and lots of carbon, you would have found different organisms. The culturable bugs anywhere are about 1% of the bugs. Not representative. > In general, multi-species biofilms are considered a norm but in > most of the studies I have come across the biofilms are usually > relatively immature. What do you mean by a "mature biofilm"? You need to think about how much energy the bacteria have available. In a deep sub-surface environment, carbon and energy are going to be in short supply. In the human mouth, hang on, here comes some more! Very different environments. Environments with high carbon and energy inputs will have a succession of comunities and preditors, and paracites. Environments with no carbon or energy inputs, such as deep sub-surface communities, are dominated by those that starve well. > Okay, someone will no doubtedly mention > human dental plaque but it is not a really mature biofilm. how > about ones that could be potentially hundreds of years old?

Dental plaque is an especially poor model for deep sub-surface bacteria. The different bugs have different problems. > Just a few questions/thoughts to ponder on!

With respect to your question about whether biofilms of denitrifying bacteria are present on clay-like materials (ceramics?), I would recommend some form of microscopy. Scanning electron microscopy, epifluorescent or confocal microscopy should be able to give you an idea of the distribution and community structure of adherent organisms. This will necessarily involve some perturbation of your fermentor during specimen removal, but would be the most direct approach to identifying whether adherent organisms were present. We had a debate in this discussion group about 6 months ago as to how many organisms constitute a biofilm. I think it safe to say that everyone agreed that one single attached microorganism was not a biofilm, and that an adherent community of microorganisms such as dental plaque was a biofilm. Between those extremes, there were some differences of opinion. Rob Palmer, currently of NIDCR, will be chairing a session at Biofilms 2000 (Big Sky Montana, USA July 16 - 20, 2000) to discuss this point. You can get some information about this meeting (which will feature most of the international biofilm researchers) on the web site for the Center for Biofilm Engineering at Montana State University http://www.erc.montana.edu or the conference web site http://www.asm.org/mtgsrc/B2Kg.htm I would really encourage you to consider attending as this will be a superb meeting.

I apologise if you have received this message twice - I am a little confused about the address nobody@net.bio.net We have the opportunity to co-supervise a PhD student working in the area of "Bacterial Attachment to Meat" with the Microbiology and Food Safety Group of AgResearch Food Science. I am posting this message to seek expressions of interest from suitably qualified graduates. The project can commence as soon as a suitable candidate is found. The project would ideally suit a microbiologist with biophysics interests, but other applicants will also be considered. The candidate will investigate the relationships between surface charge, hydrophobicity and strength of attachment, etc. with reduction of bacterial contamination the final objective. There is an established biofilm research team working at Massey University, who will provide the academic supervision and the candidate will work towards the award of a Massey University PhD. The scholarship will provide a stipend plus fees. The work will be conducted at the MIRINZ buildings on the AgResearch campus in Hamilton, working with another well established team under the MIRINZ Fellow Dr. Graham Bell.
