Even if an endospore is located in plentiful nutrients, it may fail to germinate unless activation has taken place.
Germination involves the dormant endospore starting metabolic activity and thus breaking hibernation.
Formation and destruction Endospore formation and cycle further Under conditions of starvation, especially the lack of carbon and nitrogen sources, a single endospore forms within some of the bacteria.
It is commonly characterised by rupture or absorption of the spore coat, swelling of the endospore, an increase in metabolic activity, and loss of resistance to environmental stress.
Outgrowth follows germination and involves the core of the endospore manufacturing new chemical components and exiting the old spore coat to develop into a fully functional vegetative bacterial cell, which can divide to produce more cells.
That allows the endospore to show up as red, while the rest of the cell stains blue.
