An externality is defined as a benefit or cost that is imposed on a third party, such as society, other than the producer or consumer of a good or service, or, more simply, an economic side effect.
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.
Cell structure and metabolism. Bacillus megaterium is a prokaryotic cell, lacking membrane-bound organelles. It is a Gram-positive, rod-shaped and found with other bacillus megaterium organisms. It is motile, with the use of its flagella. The cell wall, has large amounts of peptidoglycan.The flow of energy in cellular respiration is considered aerobic, but may undergo anaerobic conditions.ell structure and metabolism.
