A. The vegetative cell is one that is carrying out life functions. It is growing, dividing, transporting etc. If this cell forms a spore it is carrying out sporulation. A single spore is formed/cell, therefore this is not a reproductive process.Besides, sporulation conditions have been found to have a significant impact on the growth, germination, and wet-heat resistance of Bacillus subtilis spores (Minh et al., 2011). The sporulation temperature is associated with a decrease in the core water content, which is closely correlated with the spore wet-heat resistance (Melly et al., 2010).The optimal culture medium and the optimum external conditions for spore production are obtained. The total cell count and sporulation rate of bacteria obtained on this medium are 3.14 × 10 9 CFU/mL and 92.6%, respectively, under the optimum external conditions.

Raso et al. (1998) reported that the combination of 250 ... Increased sporulation temperatures increase mHP-mediated germination ...Germination can be triggered in some species by simply wetting dried spores (Olsen et al., 1986). It is generally accepted that germination is an osmotic event and it was proposed that the first step of the signalling cascade that triggers germination is calcium/calmodulin binding at the spore surface (Weidner and Byrd, 1982; Williams, 2009).Small, acid soluble spore proteins (SASPs) have been shown to be required for resistance of C. perfringens spores to heat, and work is also underway to identify nutrient signals required for C.perringens spore germination.
