Resumo: | Some mechanisms of selection which operate on marine Vibrio and Pseudomonas strains during survival in dilute environments have been examined. Mannitol uptake and utilisation systems are more efficient in the Vibrio strain compared with the Pseudomonas strain during starvation survival. A Vibrio mutant strain lacking mannitol uptake showed no greater loss of viability during starvation survival than mannitol positive strains. The Vibrio strain appears to be constitutive with respect to mannitol uptake systems, whereas the Pseudomonas strain examined is inducible. Active uptake systems for glucose, glutamate, alanine and aspartic acid were efficiently maintained during starvation survival in the Vibrio strain. Results suggest that membrane uptake systems are maintained during starvation survival and that they could provide a basis for the segregation and maintenance of bacterial populations in the kelp ecosystem which was observed in previous work by this group.
