A procedure for high-yield spore production by Bacillus subtilis. Presumably, as cells experience alanine starvation, Ald expression is turned down To summarize, our results provide a simple model for how phenotypic memory shapes bacterial dormancy. Annals of Animal Science. Response of single bacterial cells to stress gives rise to complex history dependence at the population level. StatSoft Inc. Indeed, memory effects may couple the heterogeneous dynamics of sporulation and spore revival at the level of the life histories of individual cells. Krauze M. This might explain why early spores form under conditions in which vegetative cells can still replicate

  • Engineering of alanine dehydrogenase from Bacillus subtilis for novel cofactor specificity.

  • L-Alanine dehydrogenase from Bacillus subtilis has a predominately ordered kinetic mechanism in which NAD binds before L-alanine. Subsequently, ammonia. Catalyzes the reversible oxidative deamination of L-alanine to pyruvate.

    Electronic supplementary material. Instead there exists a striking correlation between the timing of sporulation and the propensity of the resulting spore for nutrient-induced exit from dormancy. Coskun I. Download citation. In each case, cell-to-cell heterogeneity in the propensity to undergo conversions from one cell type to the other has been proposed to facilitate adaptive bet-hedging 13141516 Ameliorative effect of Bacillus subtilis on growth performance and intestinal architecture in broiler infected with Salmonella.
