Web3 Sep 2010 · Geobacillus stearothermophilus is a gram positive thermophilic (heat loving) bacteria characterized by a inner cell membrane and a thick cell wall. G. stearothermophilus is a rod shaped anaerob found in thermophilic habitats like thermal vents. ... The spores used in these studies are called Biological Indicators (BI’s) and offer biological ... Web1 Sep 2024 · Plates are incubated for at least 72 h at 30°C for recovery of mesophilic bacteria and 55°C for thermophilic bacteria. Suitable alternatives to specific method parameters are provided. Median values of total spore concentrations are low (<400 CFU/g for TMS and <75 CFU/g for TTS), and concentrations of HR spores are very low (<5 CFU/g).
