31. The endospore consists of the bacterium's DNA, ribosomes and large amounts of dipicolinic acid. 32. Endospores of the bacterium " Bacillus anthracis " were used in the 2001 anthrax attacks.33. Since some bacteria can form endospores any of those might survive most of the methods suggested above. 34. "Clostridium botulinum " is a large anaerobic Gram-positive bacillus that forms subterminal endospores . 35. Endospores are commonly found in soil and water, where they may survive for long periods of time.36. Certain Heliobacterium ", can form highly resistant, dormant structures called " endospores ". 37. Such endospores would be eliminated by our immune systems in children and adults, but not by infants. 38. The endospore is a dehydrated cell with thick walls and additional layers that form inside the cell membrane. 39. It lacks pigmentation, motility, and the ability to form endospores , with type strain ATCC 35263. 40. Sporulation is now complete, and the mature endospore will be released when the surrounding vegetative cell is degraded.
