This protocol is part of the bark beetle mycobiome (bbm) research coordination network. For example, total colony forming units = 1.37*10^8 cfu/ml and you want to convert it into log value, just take. These are an indication of the number of cells that remain viable enough to proliferate and form small colonies.
