Formation of the sporulation septum then captures about onethird of the chromosome in the small prespore compartment. Based on these results, the first four endospore forming strains were used to finetune the annealing temperature conditions of a gradient pcr assay between 44 and 56c. Endospore staining principle, reagents, procedure and result. Sporulation usually occurs when the bacterial cells face a nutrient deficient condition. Spoiiie is a highly conserved protein that is probably used by a wide range of bacteria to protect. The main purpose of endospore staining is to differentiate bacterial spores from other vegetative cells and to differentiate spore formers from nonspore formers. The core of the endospore becomes increasingly dehydrated during the sporulation process. The remainder of the chromosome, which is distal to oric, is then transferred through the septum by a dna transporter called spoiiie. This layer of peptidoglycan will become the cell wall of the bacterium after the endospore germinates. Cytological changes during the formation of the endospore in bacillus megatherium.
