Web Sporulation inBacillus subtilisresults in the formation of an endospore surrounded by a multilayered protective structure known as the coat.

. Web Angela Hartsock. Bacteria grow on nutrient mediums as colonies. Thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies as well on leaf surfaces aquatic environments animal feces insect-rich environments and flour mills and grain-storage.

Web In 1922 Dorner published a method for staining endosporesShaeffer and Fulton modified Dorners method in 1933 to make the process faster The endospore stain is a differential stain which selectively stains bacterial endospores. Each cell produces only one spore and each spore germinate to one vegetative cell. Web Bacillus anthracis in Gram stain.

The main purpose of endospore staining is to differentiate bacterial spores from other vegetative cells and to. Bacillus and Clostridia are spore-forming rods while Listeria and Corynebacterium are not.
