Characterization and purification of a bacteriocin produced by a potential probiotic culture, Lactobacillus acidophilus 30SC.
Lactobacillus acidophilus 30SC was tested for its potential as a probiotic culture. The strain exhibited good acid tolerance in an artificial gastric solution as well as bile resistance in media containing 0.3% bile acids. The strain produced a heat-stable antimicrobial compound that was shown to be proteinaceous in nature and, therefore, referred to as a bacteriocin. The bacteriocin was active...
متن کاملSolution structure of acidocin B, a circular bacteriocin produced by Lactobacillus acidophilus M46.
Acidocin B, a bacteriocin produced by Lactobacillus acidophilus M46, was originally reported to be a linear peptide composed of 59 amino acid residues. However, its high sequence similarity to gassericin A, a circular bacteriocin from Lactobacillus gasseri LA39, suggested that acidocin B might be circular as well. Acidocin B was purified from culture supernatant by a series of hydrophobic inter...
متن کاملGenetic analysis of acidocin B, a novel bacteriocin produced by Lactobacillus acidophilus.
The genes encoding the production of acidocin B, a bacteriocin produced by Lactobacillus acidophilus strain M46 which is active against Listeria monocytogenes, Clostridium sporogenes, Brochothrix thermosphacta, Lactobacillus fermentum and Lactobacillus delbrueckii subsp. bulgaricus, but inactive against most other Lactobacillus species, were previously localized on a 4 kb XbaI-HindIII fragment ...
متن کاملAcidolin: an antibiotic produced by Lactobacillus acidophilus.
Acidolin was isolated from skimmilk cultured for 48 hours with Lactobacillus acidophilus (CHR. HANSEN's Laboratory strain 2181). It was extracted from the skimmilk with methanol and acetone and was further concentrated and purified by Sephadex G-25 gel filtration, high voltage electrophoresis, and thin-layer chromatography on silica gel. Ultraviolet, infrared, nuclear magnetic resonance, and ma...
متن کاملIdentification and purification of a protein that induces production of the Lactobacillus acidophilus bacteriocin lactacin B.
Lactacin B is a heat-stable bacteriocin produced by Lactobacillus acidophilus N2 that is active against closely related lactobacilli, including Lactobacillus delbrueckii subsp. lactis (formerly Lactobacillus leichmannii) ATCC 4797. Pure producer cultures propagated in MRS broth (initial pH 6.5) contain no lactacin B; it is detected only in cultures maintained at pH 5.0 to 6.0 and produced optim...
