Aggregate formation in a freshwater bacterial strain induced by growth state and conspecific chemical cues

Original language description

We investigated the induction of aggregate formation in the freshwater bacterium Sphingobium sp. strain Z007 by growth state and protistan grazing. In pure cultures of Sphingobium sp. strain Z007, the concentrations of single cells and aggregates insideand outside the dialysis membranes developed in a similar manner over 3 days of incubation. Cell production of Sphingobium sp. strain Z007 was enhanced in the presence of another isolate, Limnohabitans planktonicus, outside the bags, and even more so ifthat strain was additionally grazed upon by the bacterivorous flagellate Poterioochromonas sp. The feeding of flagellates on Sphingobium sp. strain Z007 outside the dialysis bags led to significantly higher proportions of aggregates inside the bags. Thiswas not paralleled by an increase in growth rates. We conclude that two mechanisms, growth state and the possible release of infochemicals by the predator, may induce aggregate formation of Sphingobium sp. strain Z007.
