一种热球菌属嗜热古菌产耐高温α－淀粉酶的方法及产品
摘要：
本发明是一种热球菌属嗜热古菌HJ21(Thermococcus siculi HJ21)CCTCC N0：M 207010。菌株为严格厌氧的球菌，直径为0.5－1μm；菌株生长温度范围为55－94℃，其最适生长温度为88℃；最适生长pH范围为6.5－7.0，低于4.5或高于9.0菌株不生长；生长NaCl浓度范围为1－5％，2％为最适宜NaCl浓度，没有NaCl和高于5％不生长；菌株在蛋白质丰富的基质中生长良好；淀粉、麦芽糖、葡萄糖、蔗糖、纤维二糖、乳糖、糖原、明胶促进菌株生长。本发明还公开了一种利用热球菌属嗜热古菌HJ21CCTCC N0：M207010产耐高温酸性α－淀粉酶的方法及所产耐高温酸性α－淀粉酶。
摘要（英）：

This invention is a heat of thermophiles are cocci bacteria HJ21 (Thermococcus siculi HJ21) CCTCC N0: M 207010. The strain is the strict anaerobic coccus , the diameter is 0.5-1 mum ; Strain growth temperature range for 55-94degree C, Its most suitable growth temperature for 88degree C; Grows the pH scope is 6.5-7.0 suitably , It will not growth if lower than 4.5 or is higher than 9.0; Suits the growth the NaCl density scope is 1-5%, 2% NaCl concentration for the most appropriate ,no NaCl or higher than 5% will not grow ; Bacterial strain has good growth in the basal manure with rich protein; Starch, maltose, glucose, sucrose, 2 fiber sugars, milk sugar and sugar original , gelatin promotes the growth of bacterial strain. This invention still publicizes a is using hot coccus to be addict to hot ancient bacterium HJ21CCTCC N0: M207010 produces high temperature resistant acidity alpha the method of - starch enzyme and the high temperature resistant acidity produced alpha - starch enzyme.
