Tests to determine microbial contamination in fuel systems

11 Tests to determine microbial contamination in fuel systems 

There can be problems assessing microbial contamination in fuel. Because fuel is a non-aqueous media, many types of assays to determine microbial contamination cannot be used directly, such as enzyme testing. Also, the actual number of microbial contaminants may be low (10 to 10 CPU per liter of fuel) which could complicate determining the level of microbial contamination. A large proportion of particles causing filter blockage may be non-microbial.
