Initial phases of starvation and activity of bacteria at surfaces.

摘要: The activity of the hydrophilic Vibrio sp. strain DW1 and hydrophobic Pseudomonas S9, which both undergo starvation-induced responses, was examined at nutrient-enriched nutrient-deficient interfaces. initial period response to a starvation regime (“dwarfing” phase) is sequence two processes: fragmentation continuous size reduction fragmented cells. This dwarfing phase also one intense metabolic as supported by O2 uptake measurements endogenous metabolism use inhibitors proton flow, electron transport chain, membrane-bound ATPase. Hydrophilic bacteria become even smaller surfaces than in liquid upon starvation, this reflected higher exhibited surface-associated cells compared with those phase. On other hand, did not exhibit greater an that only slightly Bacterial scavenging surface-localized nutrients related degree irreversible binding dwarf starved bacteria, turn may be cell surface hydrophobicity.
