B. Atkinson
1973 Pure and Applied Chemistry  
Microbial mass can be said to occur in one of two states; as 'flocs' frcely suspended in an aqueous medium, or as a 'film' adhering to a support surface. Industrial fermenter configurations, at least since the development of deep-tank fermentation, have almost invariably been based on the use of microbial flocs, and the occurrence of a visible microbial film during fermentation is generally avoided.
