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 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...
متن کاملGrowth of Bacillus coagulans in chemically defined media.
A nutritional study was made of five strains of Bacillus coagulans obtained from various culture collections. These five strains were descendants of two original isolates; three had been derived from one parent culture in years past and the other two were transfers from another parent culture. Therefore, the five cultures should have represented two distinct groups of genetically identical cult...
متن کاملScreening of different media for sporulation of Bacillus megaterium
Five different sporulation medium such as tryptone yeast extract (TYE) broth, tryptone glucose yeast extract (TGYE) broth, minimal media, Sucrose salt medium, Arret & Krishbaum (AK)sporulation agar were screened for spore production in Bacillus megaterium ATCC 9885. During this study, it was observed that out of different combinations of tryptone, yeast extract and dextrose sporulation was maxi...
