Detailed explanation-1: -Around the outer membrane is the endospore coat [25]. The coat is a multilayered semipermeable structure composed mostly of tyrosine-and cysteine-rich proteins [40, 41]. The coat can contain upwards of 50 different proteins, most of which are endospore-specific gene products [42].

Detailed explanation-2: -Bacterial endospores are simplified forms of the bacteria, consisting of the DNA genome, some small amount of cytoplasm, and a specialized coating that confers resistance to heat, radiation, and other harsh external conditions.

Detailed explanation-3: -Typically, Gram-positive bacteria are best known for producing intracellular spores called endospores as a survival mechanism. Endospores are highly retractile and thick-walled structures formed inside the bacterial cells. It is most common for Bacillus species as well as Clostridium species to create endospores.[1] B.

Detailed explanation-4: -Spore-forming bacteria include Bacillus (aerobic) and Clostridium (anaerobic) species. The spores of these species are dormant bodies that carry all the genetic material as is found in the vegetative form, but do not have an active metabolism.
