Article Abstract:
The resistance of Vibrio rumoiensis S-1 to hydrogen peroxide has been studied. The strain was isolated from the drain pool of a fish processing plant which uses H2O2 as the bleaching and microbiocidal agent. The effects of H2O2 on the growth and structure on the growth of V. rumoiensis S-1 cells were compared with those of a spontaneous mutant without the catalase activity and other bacterial strains. Results reveal that the mutant strain did not survive in the presence of five mg of H2O2. This finding suggests that catalase is involved in the resistance and survival of V. rumoiensis S-1 in the presence of H2O2.

Article Abstract:
The physiological functions and the antioxidative effects of eicosapentaenoic acid (EPA) and docasahexaenoic acid (DHA) in bacterial and other microbial systems in marine environments are studied. Microarray and proteomics methods are useful in describing the inter-relationship between oxidative stress and environmental stimuli.

Article Abstract:
The bacterial genes responsible for the biosynthesis of eicosapentaenoic acid (EPA) and docosahexanenoic acid (DHA), covering aspects such as gene cloning, characterization of the structure of the genes, their domain structures, and recombinant production of EPA and DHA is reviewed.
