METABOLIC-ACTIVITY OF CADMIUM-STRESSED AND OR STARVED VIBRIO SP/

Starvation of Vibrio sp. strain S14 cells for at least 2.5 h induced a n enhanced resistance to subsequently applied cadmium stress. Bacteria l cultures starved for a shorter time (0-2 h) exhibited a decreased ab ility to incorporate glucose when exposed to Cd2+. Cyclic increase and decrease in protein synthetic activity of stressed vibrios reflect st ages of starvation-induced proteins expression. Vibrio cells pre-stres sed by Cd2+ addition or by starvation responded in many aspects simila rly to the next stress challenge. The presence of 100 mg/L chloramphen icol significantly lowered cell resistance against the secondary stres s. Proteins synthesized due to the primary stress provide Vibrio S14 w ith an enhanced probability to survive in unfavourable environment.
