Biosan Laboratories is an environmental microbiology laboratory that was founded by Dr. Harold Rossmoore in 1973. Our initial microbiology lab was in Ferndale, MI where we remained until 1994. Since we knew many of our lab customers would benefit from the ability to perform microbiology testing on-site, Biosan developed the following bacteria and fungi test kits: the Sani-Check AB for detecting bacteria, the Sani-Check YM for detecting fungi, the Sani-Check SRB kit for detecting anaerobic sulfate reducing bacteria.
