Geobacillus stearothermophilus

Tantalean JC, MA Araya. CP Saavedra, DE Fuementes, JM Perez, IL Calderon, P Youderian, CC Vasquez (2003) The Geobacillus stearothermophilus V iscS gene, encoding cysteine desulfurase, confers resistance to potassium tellurite in Escherichia coli. J Bacteriol 185 5831-5837. 

Unusual reactions have been encountered in the aerobic degradations carried out by Azoarcus evan-sii and Geobacillus stearothermophilus (Zaar et al. 2001). The anaerobic degradation of benzoate by Azoarcus evansii (Ebenau-Jehle et al. 2003) and Thauera aromatica (Domer and Boll 2002), and of 3-hydroxybenzoate by Th. aromatica (Laempe et al. 2001) is discussed later.

CGTases from Geobacillus stearothermophilus and Thermoanaerobacter sp. gave higher yields compared to those from Bacillus macerans and B. circulans (Figure 24.3). High thermal stability of the former enzymes allowed relatively high... 

Geobacillus stearothermophilus is a thermophile and grows at temperatures between 50 °C and 65 °C. It is used as a test organism (biological indicator) to verify the efficacy of moist heat sterilisation processes. 

The overkill process is often used in daily practice and is based on the principle that the process should be sufficiently powerful to reduce a severe contamination with a very thermo-resistant organism, i.e. circa 10 spores of Geobacillus stearothermophilus, to the SAL 10 . The standard process for steam or hot water sterilisation in the...

Werz et al. have reported a strategy for the construction of an a-linked undecaprenyl diphosphate trisaccharide (48) consisting of one Z)-galactose and two L-rhamnose units from the bacterium Geobacillus stearothermophilus. The compound (48) was assumed to be a key intermediate in the construction of the surface-layer of Geobacillus stearothermophilus ...
