Culture counts of Escherichia coli O157:H7 showed that colicin V caused rapid death in buffered (pH 7) cell suspensions at 30C. A decrease in optical density of cell suspensions indicated that colicin V lysed cells. Decreased optical densities were p

Toluene-induced cells of Pseudomonas putida PaW164 (pWWO-164) were monitored for growth potential, maintaining the TOL plasmid, and potential toluene mineralization activity in toluene-amended and nonamended soil. A follow-up study was done in a carb

Actively growing Zostera marina plants had a greater rhizosphere inorganic phosphate solubilizing potential than dormant plants. Rhizosphere bacteria that were capable of calcium phosphate solubilization were obligate aerobes and numbered approximate
