摘要：
A new isolated Bacillus strain was cultivated continuously at 68-degrees-C and pH 3 for a long time. Extractable lipids represent about 3.6% of cell dry weight and are made up of 18% neutral lipids, 39.3% glycolipids, and 42% acidic lipids. Main components of the fatty acid fraction are omega-cyclohexylundecanoic acid and omega-cyclohexyltridecanoic acid, respectively. MK-7 and hop-22(29)-ene are components of the unsaponifiable fraction. The glycolipid fraction contains the pentacyclic triterpenoid tetrahydroxybacteriohopane. Based on the thermoacidophilic growth conditions, the morphologic and physiological properties, and the nature of lipids, it can assumed that the new isolated strain belongs to the species Bacillus acidocaldarius.
