8/3/2023 0 Comments Spore forming bacteriaDue to their high adaptability, bacterial endospores are omnipresent: as undesirable permanent guests in areas with high hygiene requirements, but also as highly biotechnologically useful target of industrial production, for example in probiotics for animal breeding and in biological plant protection. When environmental conditions are suitable again, they revive within minutes and form a new cell that is capable of reproduction. Like tiny space capsules, endospores protect the bacterial genome from heat, drought and starvation. These findings have implications for our understanding of the ecology of spore-forming bacteria and for the development of biotechnological products for organic farming. Time-lapse microscopy studies suggest that the bacteria can either make more or better spores, and that natural isolates follow different life cycle strategies. Bacillus subtilis can survive unfavorable living conditions by forming endospores. This also applies to spore-forming bacteria. Terrestrial Microbiology/ Bischofs-Pfeiferīecause natural resources are always limited, the right strategy decides about success in life. According to their sporulation time, "early" and "late" spores can be distinguished. After four days (almost) all cells have sporulated. In each cell cycle, the individual cell decides whether it will divide or initiate sporulation. The spores develop from a precursor cell over a period of several days. Left: Staggered sporulation middle: early and late spores right: selective spore revival. Spore formation is a multicellular process.
