You can probably glean some info from this older thread on species ID:
http://groups.google.com/group/diybio/browse_thread/thread/449334a66c22444a

specifically this post from that thread:

The old-fashioned approach would be to get out "Bergey's Manual", aka
Bergey's Manual of Determinative Bacteriology:

Here's a great identification flowchart, extracted from the dozens and
dozens of tables in the book:

http://www.uiweb.uidaho.edu/micro_biology/250/IDFlowcharts.pdf

If you already have a good idea which organism it may be (e.g. B.
subtilis), you may want to get out the big guns, and check Bergey's
Manual of *Systematic* Bacteriology, which will have a lot more
information of specific species phenotypes, beyond merely what is
essential for identifying the species.

Of course, nowadays the gold standard would be to sequence the 16S
rDNA, and use that to identify the organism down to the strain level.
