Question

Of the microorganisms tested for endospore formation, which had sporulated and which had not? What triggered sporulation induction in these cells? For each species, describe what information we can infer about the bacteria from these results. The organisms tested were Bacillus subtilis and Corynebacterium glutamicum

Answer 1

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, and one side then engulfs the other. Endospores enable bacteria to lie dormant for extended periods even centuries. Here bacillus subtilis forms endospore.
