| Abstract | The density of prosthecate bacteria was determined by direct and viable counting techniques in samples of water from polluted Red Cedar River, Michigan. These bacteria comprised from 0.62 to 1.1% of the total microflora. The caulobacteria were the predominant type, attaining the maximum density of 4000/ml. The other prosthecate forms, including Prosthecomicrobium, Hyphomicrobium, and Ancalomicrobium, were usually present at numbers less than 1/ml. No correlation between the frequency of prosthecate bacteria and that of coliforms was observed. |
