Notes

A zoogloea-forming bacterium was isolated from activated sludge and identified tentatively as belonging to the genus Zoogloea. The bacterium grew in liquid media with the formation of amorphous gelatinous colonies in which the bacterial cells were sparsely embedded. The gelatinous substance was isolated and purified partially: it was a mucopolysaccharide composed primarily of two amino sugars. One of these sugars was identified as N-acetyl-glucosamine, and the other was suggested to be N-acetylfucosamine. The molar ratio of the former to the latter was approximately 1:2. The polymer was quite resistant to the action of the microfloras from wastewater and soil.
