| 41. | The impermeability of the spore coat is thought to be responsible for the endospore's resistance to chemicals.
|
| 42. | There are different types of spores including endospores, exospores, and spore-like structures called microbial cysts.
|
| 43. | It is Gram-positive, motile, endospore-forming, rod-shaped and arsenic-resistant.
|
| 44. | It is Gram-positive, motile by peritrichous �agella, endospore-forming, halotolerant and facultatively alkaliphilic.
|
| 45. | It is a moderately halophilic, endospore-forming bacterium originally isolated from permafrost in the Canadian high Arctic.
|
| 46. | Terbium is also used to detect endospores, as it acts as an assay of dipicolinic acid based on photoluminescence.
|
| 47. | Dipicolinic acid is a spore-specific chemical that appears to help in the ability for endospores to maintain dormancy.
|
| 48. | Prolonged exposure to ionising radiation, such as x-rays and gamma rays, will also kill most endospores.
|
| 49. | Even if an endospore is located in plentiful nutrients, it may fail to germinate unless activation has taken place.
|
| 50. | This conformational change in the protein is thought to be responsible for exposing active enzymatic sites necessary for endospore germination.
