''Geobacillus thermoglucosidasius'' is a thermophilic gram-positive bacterium, and a member of the ''Firmicutes'' phylum. It was first isolated from soil in Japan in 1983. The species name ''thermoglucosidasius'' comes from the words ''therme'' denoting heat, and ''glucosidasius'' denoting starch-hydrolyzing glucosidase activity. ==Biology and biochemistry== ''G. thermoglucosidasius'' is gram-positive (bacterium that retains Crystal violet dye during gram-staining) and facultatively anaerobic(produces ATP by aerobic respiration if oxygen is present, but capable of switching to fermentation or anaerobic respiration if oxygen is absent) . ''G. thermoglucosidasius'' is classified as a thermophile as optimal growth occurs at 60 °C (140 °F), although strains have demonstrated ability to grow at temperatures between 37 °C (98.6 °F) and 68 °C (154.4 °F). Their rod-shaped cells are less than 3.0 micrometers (μm) long and less than 0.9 μm in diameter. Under a microscope, the cells are observed to occur either singly or in short chains, while possessing peritrichous fagella for motility or appearing non-motile. Vegetative ''G. thermoglucosidasius'' sporulates, producing one endospore per cell located terminally or subterminally in slightly swollen or non-swollen sporangia. It can live on a wide variety of substrates. ''G. thermoglucosidasius'' uses mixed-acid fermentation in anaerobic conditions, producing lactate, succinate, formate, ethanol, acetate and carbon dioxide. Growth can be driven by aerobic or anaerobic respiration, using a large variety of redox pairs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Geobacillus thermoglucosidasius」の詳細全文を読む スポンサード リンク
