Brief Method Summary. 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.But how to calculate MPN/100 ml based on 5 tube method and how many dilutions are to be followed?

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.As shown in Table 1, counts from Legiolert ranged from 0 to 1,460 MPN 10 ml −1 (mean 37.4), and from 0 to 50 cfu 10 ml −1 (mean 5.3) from SM9260 J method. The majority of paired results (64 out of 74, i.e. 86.5%) were from a SM9260 plate count range of 0 to 10 cfu, but were encompassed within a count range of 0 to 172 MPN by Legiolert.1.5 This method may be used to determine the density of fecal coliform bacteria in Class A and Class B biosolids to satisfy the pathogen reduction requirements of Subpart D of Part 503.
