The effect of certain sporulation conditions on the thermal death rate of Bacillus coagulans var. thermoacidurans.
One of the fundamental properties of spores which is of paramount interest to the food microbiologist is their extraordinary thermal resistance. In the canning of food products, the commercial thermal process, in order to be successful, must rid the product completely of the spores of Clostridium botulinum, and nearly so of all other types commonly associated with the raw material or encountere...

متن کاملNisin 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). ...
متن کاملSurfactin 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 ...
متن کاملEffect of divalent cations in the sporulation medium on the thermal death rate of Bacillus coagulans var. thermoacidurans.
In a previous paper, El-Bisi and Ordal (1956a) reported that increased levels of phosphate, in the growth and sporulation medium, significantly reduced the thermal resistance of spores of Bacillus coagulans var. thermoacidurans. It was postulated that the phosphate anion lessened the availability of divalent cations to the sporulating cells and that spores so produced possessed a reduced therma...
