Counting viable Azotobacter in vertisols


In counting Azotobacter in vertisols by the soil dilution and spread-plating method, mean colony counts/plate did not decrease in proportion to the dilution factor and consequently derived counts of Azobacter cells/g soil decreased with increasing dilution of the soil suspension. This non-proportionality phenomenon was analysed in several experiments with… (More)
