| Abstract |
Investigations were conducted into the effect of 3 marine bacteria, Vibrio anguillarum #19264, V. anguillarum # 19109, and Escherichia coli, on the growth of 10 phytoplankters. A disc method on agar plates was used to evaluate growth responses. Growth enhancement of all algae in the presence of V. anguillarum # 19264 occurred on an enriched agar medium; the other bacteria yielded variable responses. Evidence available is consistent with the hypothesis that growth enhancement of algae is related to the release of stimulating substances through bacterial hydrolysis of the agar. |
