A fosfomycin-hypersensitive mutant, f-360, was isolated from Staphylococcus aureus Newman by selection with fosfomycin, an antibiotic that inhibits synthesis of the bacterial cell wall. The mutant f-360 was 50-fold more sensitive than the parent strain to fosfomycin. The mutant was constitutive for the hexose phosphate transport system. Using the organism in screening, BA-3796, which had an antibacterial activity against mutant f-360 was found to be produced by a bacterium designated Bacillus sp. BA-3796. Starch and beef extract were the most suitable carbon and nitrogen sources for BA-3796 production and the amount of BA-3796 reached 3 g/l at a maximum level. The purified BA-3796 was identified as α-d-glucose-l-phosphate by its various physiochemical properties. α-d-Glucose-1-phosphate showes an antibacterial activity against Staphylococci in the presence of a slight amount pf α-d-glucose-6-phosphate.</div>","PeriodicalId":15702,"journal":{"name":"Journal of Fermentation Technology","volume":"66 6","pages":"Pages 649-655"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0385-6380(88)90069-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76932647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conjugate has about two molecules of active and covalently linked NAD per tetramer. The specific activity of the enzyme moiety of the conjugate in the presence of exogenous NAD is about 77% of that of the native enzyme, and this decrease is mainly due to the decrease in the Vmax value. The conjugate has the same pH-stability profile as the native enzyme and an internal activity of 0.26s−1 (as a monomer); its NAD moiety has similar coenzyme activity to poly(ethylene glycol)-bound NAD. These results indicate that GlcDH-PEG-NAD can be used as an NADH-regeneration unit for many dehydrogenase reactions. The coupled reaction of GlcDH-PEG-NAD and lactate dehydrogenase was then studied. The specific activity of the conjugate is 1.1 s−1 (as a tetramer), the recycling rate of the active NAD moiety is 0.54 s−1, and the apparent Km value for glucose is 24 mM. Kinetically, lactate dehydrogenase behaves like a substrate with an apparent Km value of 1.8 units·ml−1 in this coupled reaction system with low coenzyme concentration. l-Lactate was continuously produced from pyruvate in a reactor with a PM10 ultrafiltration membrane, and containing GlcDH-PEG-NAD and lactate dehydrogenase. GlcDH-PEG-NAD proved to be applicable in continuous enzyme reactors as an NADH-regeneration unit with a large molecular size.</div>","PeriodicalId":15702,"journal":{"name":"Journal of Fermentation Technology","volume":"66 3","pages":"Pages 267-272"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0385-6380(88)90103-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89333861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
