The bacteria is a thermophile and is widely distributed in soil, hot springs, ocean sediment, and is a cause of spoilage in food products. It will grow within a temperature range of 30-75 degrees Celsius. Some strains are capable of oxidizing carbon monoxide aerobically.iological indicators are used in conjunction with chemical indicators and process indicators to validate sterilization processes. It was first described in 1920 as Bacillus stearothermophilus, but, together with Bacillus thermoglucosidasius, it was reclassified as a member of the genus Geobacillus in 2001.
Making the world better, one answer at a time. Bacillus anthracis are rod shaped, gram positive bacteria. Their endospores are the infectious agents of anthrax. The infection is fatal in both animals and humans.The major symptoms are vomiting blood, respiratory collapse, severe diarrhea, skin lesions with boils, and acute inflammation.his component forms the outer leaflet of the outer membrane. Gram-positive bact â¦ eria do not have an outer membrane or lipopolysaccharide and thus polymixin antibiotics are unable to bind to the cell.
