Detailed explanation-1: -When a bacterium detects environmental conditions are becoming unfavourable it may start the process of endosporulation, which takes about eight hours. The DNA is replicated and a membrane wall known as a spore septum begins to form between it and the rest of the cell.
Detailed explanation-2: -Endospore Formation and Structure. Endospores are formed in response to unfavorable growth conditions in the bacterial environment, most commonly induced by the limitation of nutrients. Sporulation, however, is not the first response of the bacterial cell to nutrient depletion.
Detailed explanation-3: -Endospore formation is usually triggered by a lack of nutrients; it is a stripped-down, dormant form to which the bacterium can reduce itself. The endospore consists of the bacterium’s deoxyribonucleic acid (DNA), ribosomes, and large amounts of dipicolinic acid.
Detailed explanation-4: -Endospore formation is usually triggered by lack of nutrients, and usually occurs in Gram-positive bacteria. In endospore formation, the bacterium divides within its cell wall. One side then engulfs the other. Endospores enable bacteria to lie dormant for extended periods, even centuries.
Detailed explanation-5: -The spore is formed as a response to adverse conditions. Bacterial spore is a resistant structure to unfavorable environmental conditions. Each cell produces only one spore and each spore germinate to one vegetative cell. The spore is just a part of the life cycle of spore forming bacteria under unfavorable conditions.
