Depending on how much money you have you can try the Biolog system (http://www.biolog.com/products-static/microbial_identification_overview.php) or even a smaller array systems like the API (http://www.biomerieux-usa.com/servlet/srt/bio/usa/dynPage?doc=USA_PRD_LST_G_PRD_USA_5). They both have options for the number of isolates you want to identify, the kindom (bacteria, fungi) and the origin of the microbe.
