Jenseniin G, a heat-stable bacteriocin produced by Propionibacterium jensenii P126.
The genus Propionibacterium includes cutaneous species typically found on human skin and the dairy or classical species (Propionibacterium freudenreichii, P. jensenii, P. thoenii, and P. acidipropionici) used industrially for the production of Swiss cheese and propionic acid. Grinstead (1989, M.S. thesis, Iowa State University, Ames) has previously observed that some dairy propionibacteria inhi...
متن کاملOrganic Acid Production by Propionibacterium shermanii: Effect of pH, Temperature and Vitamin-Nitrogen Source
Production of propionic acid by Propionibacterium shermanii CDB 10014 was enhanced by a pH value of 6.5 and by temperatures in the range 35-37 °C. Depending on the type of yeast extract, succinic acid can be produced in higher proportions, with decreasing propionic acid yields. With respect to propionic acid production, Difco yeast extract has shown the best results when yeast extract preparati...
متن کاملBacteriocin production by strains of Neisseria meningitidis.
Kingsbury, David T. (Naval Medical Research Institute, Bethesda, Md.). Bacteriocin production by strains of Neisseria meningitidis. J. Bacteriol. 91:1696-1699. 1966.-Strains of Neisseria meningitidis produce substances inhibitory to other strains of meningococcus. These substances are nontransmissible and show a high degree of strain specificity. The properties of one of these substances resemb...
متن کاملLactococcin G is a potassium ion-conducting, two-component bacteriocin.
Lactococcin G is a novel lactococcal bacteriocin whose activity depends on the complementary action of two peptides, termed alpha and beta. Peptide synthesis of the alpha and beta peptides yielded biologically active lactococcin G, which was used in mode-of-action studies on sensitive cells of Lactococcus lactis. Approximately equivalent amounts of both peptides were required for optimal bacter...
متن کاملMagnetic/pH-sensitive nanocomposite hydrogel based carboxymethyl cellulose –g- polyacrylamide/montmorillonite for colon targeted drug delivery
Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide (MBA) as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and magnetic montmorillonite ( mMT) nanoclay as nano-...
