Glyoxylate metabolism in growth and sporulation of Bacillus cereus.
Megraw, Robert E. (Iowa State University, Ames), and Russell J. Beers. Glyoxylate metabolism in growth and sporulation of Bacillus cereus. J. Bacteriol. 87:1087-1093. 1964.-Isocitrate lyase and malate synthetase were found in cell-free extracts of Bacillus cereus T. The patterns of synthesis of enzymes of the glyoxylic acid cycle were dependent upon the medium in which the organism was grown. C...
متن کاملOrganic Nutrients Required for Growth and Sporulation of Bacillus Cereus.
E spores. This concentration is obtained by simple mixing of equal parts of absolute ethanol and the enrichment culture prepared as follows. When the presence of type E toxin was demonstrated in the suspect fish by titrations with mice, portions of the sample were cultured in duplicate tubes of cooked meat medium (CMM) prepared from fresh liver and Trypticase-peptoneglucose (TPG) broth (Schmidt...
متن کاملInorganic polyphosphate in Bacillus cereus: motility, biofilm formation, and sporulation.
Chains of inorganic polyphosphate (poly-P) with hundreds of P(i) residues linked by phosphoanhydride bonds, as in ATP, are found in every bacterial, fungal, plant, and animal cell, in which they perform various functions. In the spore-forming Bacillus cereus, we have identified three principal enzymes and genes involved in the metabolism of poly-P, namely, (i) poly-P kinase (PPK), which synthes...
متن کاملBacillus cereus in probiotic 11 PROPERTIES OF THE BACILLUS CEREUS STRAIN USED IN PROBIOTIC CenBiot
Bacillus cereus CenBiot fulfilled the requirements to be used as probiotic. The spores showed D 80 of 14 hs, inhibited Escherichia coli and Yersinia pseudotuberculosis after 24 hs in associative culture, were innocuous for suckling and adult mice and were not inhibited by antibiotics at low concentrations.
متن کاملBiochemical changes occurring during sporulation of Bacillus cereus. Inhibition of sporulation by alpha-picolinic acid.
The effects of nutritional and environmental conditions on sporulation and the properties of the spore have been extensively studied with the hope that these may provide a clue to the mechanism of dormancy and resistance of the bacterial endospore. However, there is no general agreement and our knowledge of these is still limited. The extensive literature dealing with the various aspects of spo...
