The induction of DnaK and GroEL homologous proteins by heat‐shock and long‐term carbon starvation was studied in Vibrio vulnificus, Vibrio sp. strain S14, and Vibrio sp. strain DW1. In each Vibrio strain one protein (60 kDa) reacted with antibodies against Escherichia coli ‐GroEL and two proteins, DnaK (69 kDa) and Sis1 (62‐60 kDa), reacted with antibodies against E. coli ‐Dnak. The carbon starvation elicited induction of the stress proteins was strain‐specific, suggesting that the induction of stress proteins like DnaK and GroEL in marine Vibrios might not be a uniform starvation response. It appears as of these proteins, only DnaK in Vibrio sp. strain S14 remains induced after long‐term carbon starvation in the three marine bacterial strains that were tested.
