	Metabolic test systems such as Biolog or API, and the fatty acid based
MIDI system (from Hewlett-Packard) are simple and reliable.  The first
problem is that these systems were designed for pathogens, and their
databases are preponderantly pathogens.  I have heard that recently they
have entered more environmental isolates.  The second problem is that
there are many more bacterial "species" than have been or possibly ever
be cataloged.  

	16s rRNA sequencing would be the prefered method, if you can afford

Technical writing, literature search, and data analysis at the interface
of chemistry and biology.
