Nisin sensitivity of Bacillus coagulans.

Previous investigations have revealed that Bacillus coagulans strain 43P is sensitive to the polypeptide antibiotic nisin (O'Brien et al., 1956; Campbell and Sniff, 1959; Campbell, Sniff, and O'Brien, 1959). It has also been found that nisin is effective in the control of the flat sour spoilage of tomato juice in inoculated pack studies with this strain of B. coagulans (Campbell et al., 1959). ...

Efficient Conversion of Phenylpyruvic Acid to Phenyllactic Acid by Using Whole Cells of Bacillus coagulans SDM

BACKGROUND Phenyllactic acid (PLA), a novel antimicrobial compound with broad and effective antimicrobial activity against both bacteria and fungi, can be produced by many microorganisms, especially lactic acid bacteria. However, the concentration and productivity of PLA have been low in previous studies. The enzymes responsible for conversion of phenylpyruvic acid (PPA) into PLA are equivocal....

Surfactin isoforms from Bacillus coagulans.

Bacillus coagulans has been found to produce several surfactins that are powerful lipopeptide surfactants. Four main components with molecular weights 1007, 1021 and 1035 Da were separated. Their structures have been confirmed by spectrometric and spectroscopic studies and by acid hydrolysis. The compounds were found to represent two pairs of surfactin isoforms in which beta-hydroxy-iso-C14 or ...

Folic acid and the methylation of homocysteine by Bacillus subtilis.

1. Cell-free extracts of Bacillus subtilis synthesize methionine from serine and homocysteine without added folate. The endogenous folate may be replaced by tetrahydropteroyltriglutamate or an extract of heated Escherichia coli for the overall C(1) transfer, but tetrahydropteroylmonoglutamate is relatively inactive. 2. Extracts of B. subtilis contain serine transhydroxymethylase and 5,10-methyl...
