✦ Synopsis

Amino acid-starved cells of Escherichia coli relA +, which contain a targe number of glycogen part,ties, are able to survive in phosphate buffer for a longer time period than their relaxed counterparts. With regard to NH f starvation differences in the survival of both strains were not found.

H + N 4 starved cells of E. coli relA are able to synthesize glycogen but amino acid-starved cells of the reIA strain are not. We suggest that the synthesis of glycogen triggered by guanosine tetraphosphate during amino acid starvation is responsible for the prolonged viability of the E. coli relA + strain.

## Abstract The role of free amino acids as solutes for cell volume regulation in marine molluscs under salinity stress is well established. Under hypoosmotic stress the intracellular concentrations of amino acids decrease by extrusion from the cells, followed by deamination and/or excretion. Howev
