Mesophilic sporeformers all belong to the Genus Clostridium. There are two main classifications: Proteolytic and Non-proteolytic anaerobes. If counts need to be expressed solely on the basis of spores present the lab must be notified (vegetative cells must be destroyed prior to enumeration).
50g minimum sample is recommended. Environmental surface samples can also be analyzed.
EMSL Test Code: F117Sample retention time – 30 days, unless highly perishable
