Inorganic 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 Biofilms—Same, Only Different
Bacillus cereus displays a high diversity of lifestyles and ecological niches and include beneficial as well as pathogenic strains. These strains are widespread in the environment, are found on inert as well as on living surfaces and contaminate persistently the production lines of the food industry. Biofilms are suspected to play a key role in this ubiquitous distribution and in this persisten...

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 کاملThe comER Gene Plays an Important Role in Biofilm Formation and Sporulation in both Bacillus subtilis and Bacillus cereus
Bacteria adopt alternative cell fates during development. In Bacillus subtilis, the transition from planktonic growth to biofilm formation and sporulation is controlled by a complex regulatory circuit, in which the most important event is activation of Spo0A, a transcription factor and a master regulator for genes involved in both biofilm formation and sporulation. In B. cereus, the regulatory ...
