Attachment properties of Flavobacterium-Cytophaga.

Attachment of bacteria to solid surfaces was examined using glass cover slips immersed in a peptone medium.The numbers of attached cells of Flavobacterium-Cytophaga strains at 1000 and 100 ppm of the nutrient concentrations ranged from 107 to 106/cm2 and were larger than those of Pseudomonas, Vibrio and Acinetobacter strains which ranged from 106 to 103/cm2.The numbers of attached cells of Flavobacterium-Cytophaga strains at 1000 ppm of the nutrient concentration were larger than those at 100 ppm, while the numbers of attached cells of Vibrio strains were larger at the lower nutrient concentration.Attachment to solid surfaces seemed to favour the development of Flavobacterium-Cytophaga populations on the surfaces of Enteromorpha linza (Linne) J.
