Última Adaptive features of a bacteriolytic enzyme from the style of the mussel Choromytilus meridionalis in response to environmental fluctuations. ArchiMer Seiderer, L; Robb, F. The extracellular digestive apparatus of bivalve molluscs consists of a crystalline style containing diverse degradative enzymes which are released during rotation and dissolution of the style. This paper reviews the occurrence of a temperature-regulated bacteriolytic enzyme in the black mussel Choromytilus meridionalis , which is an inhabitant of coastal reefs on the south and south west coast of South Africa. This agent is unable to lyse Micrococcus luteus or Escherichia coli , both of which are susceptible to lysis by a true lysozyme. It appears to have a restricted spectrum of activity which includes both free-living and kelp-associated gram-negative bacteria. In addition, the level of activity varies dramatically according to the environmental water...

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...
