Abstract. The number of hydrocarbon-degrading microorganisms in environmental samples or liquid cultures can be determined by the most probable number (MPN) methods. These procedures are based on serial dilution of the sample and subsequent determination of the presence or absence of degrader cells for several subsamples of each dilution.

Requires the addition of a dilution series of the sample to tubes of EC medium or A-1 broth. For EC medium, incubate at 44.5+-0.2C for 24 h. For A-1 broth, incubate for 3 h at 35+-0.5C and then 21 h at 44.5+-0.2C. The presence of gas production in EC medium or A-1 broth is a positive test for fecal coliforms.MPN is also used to estimate the number of a particular type of microbial pathogens in water, such as Salmonella, utilizing the resistance of Salmonella to malachite green. A further application is the estimation of mycorrhizal fungi by inoculating soil dilutions onto a plant host and looking for root colonization by the fungi.number (MPN) per four grams of total solids (dry weight basis) at the time the biosolids are used or disposed.
