regulation of hut enzymes and intracellular protease activities in vibrio alginolyticus hut mutants.the production of alkaline protease, collagenase and histidine utilization (hut) enzymes by vibrio alginolyticus wild-type, huth1 and hutu1 strains was investigated. alkaline protease synthesis was stimulated by histidine and urocanic acid in the wild-type and hutu1 strains. the huth1 mutant alkaline protease production was stimulated by urocanic acid and not by histidine. the hut enzymes in the wild-type strain were coordinately induced by histidine. urocanase and formimino-hydrolase were induc ...19826129284

peptone induction and rifampin-insensitive collagenase production by vibrio alginolyticus.vibrio alginolyticus produces an extracellular collagenase which requires specific induction by collagen or its high-molecular-weight fragments. peptone also induces collagenase during the late exponential and early stationary growth phases. the peptone inducers have been shown to have a broad molecular weight range between 1,000 and 60,000. the peptone inducers supported slow growth of v. alginolyticus when supplied as the sole nitrogen source in minimal medium. digestion of the peptone inducer ...19806247322
regulation of exoprotease production by temperature and oxygen in vibrio alginolyticus.the production of an extracellular collagenase and alkaline protease by vibrio alginolyticus during stationary phase was inhibited by a temperature shift from 30 to 37 degrees c and by a lack of oxygen. the stability of the exoproteases was unaffected by incubation at 37 degrees c and aeration. the optimum growth temperature for the v. alginolyticus strain was 33.5 degrees c and there was no difference in the growth rate at 30 and 37 degrees c. aeration enhanced the rate of growth of exponential ...19816277266

halophilic vibrio species from seafish in senegal.sucrose-positive and sucrose-negative halophilic vibrio species at counts of up to 10(7)/100 g were isolated from muscles tissue in 27 and 43%, respectively, of 128 seafish from coastal waters in senegal. vibrio parahaemolyticus, including 21% urease-positive strains, was the most common isolate, followed by vibrio alginolyticus, vibrio vulnificus, vibrio damsela, and vibrio fluvialis.19846476829
k+/h+ antiporter functions as a regulator of cytoplasmic ph in a marine bacterium, vibrio alginolyticus.the marine bacterium, vibrio alginolyticus, regulates the cytoplasmic ph at about 7.8 over the ph range 6.0-9.0. by the addition of diethanolamine (a membrane-permeable amine) at ph 9.0, the internal ph was alkalized and simultaneously the cellular k+ was released. following the k+ exit, the internal ph was acidified until 7.8, where the k+ exit leveled off. the k+ exit was mediated by a k+/h+ antiporter that is driven by the outwardly directed k+ gradient and ceases to function at the internal ...19846477914
