Changes of bacterial flora in stored seawater and in incubated seawater inoculated with Vibrio parahaemolyticus.

Abstract

Changes of bacterial flora in natural seawater and in seawater inculated with Vibro parahaemolyticus during storage were examined. In both samples, the dominant group of bacteria changed rapidly, although the total number of viable bacteria maintained a constant level after the initial increase. The organic substrate decomposer groups, such as Alteromonas and Vibio, which were initially the predominant groups in the natural seawater, were rapidly replaced by the organic substrate nondecomposer groups, such as Pseudomonas, Moraxella and Acinetobacter.
