一株产α-淀粉酶的耐高温地衣芽孢杆菌
摘要：
一株产α-淀粉酶的耐高温地衣芽孢杆菌，它涉及一株地衣芽孢杆菌。它解决了现有产α-淀粉酶的工程菌株都不耐高温的问题。其为地衣芽孢杆菌(Bacillus licheniformis)HWyb1401，保藏于中国微生物菌种保藏管理委员会普通微生物中心，保藏号为CGMCC No.8718。本发明地衣芽孢杆菌(Bacillus licheniformis)HWyb1401具有耐高温特性，在70℃条件下仍能存活，并代谢出α-淀粉酶，55℃其发酵液中α-淀粉酶的酶活力可达70U/mL。
摘要（英）：

The invention relates to high-temperature-resistant bacillus licheniformis capable of producing alpha-amylase and relates to bacillus licheniformis, solving the problem that existing engineering strains for producing alpha-amylase are unable to resist high temperature. The high-temperature-resistant bacillus licheniformis is bacillus licheniformis HWyb1401 which is preserved in CGMCC with the preservation number of CGMCC No. 8718. The bacillus licheniformis HWyb1401 provided by the invention has a high-temperature-resistant characteristic and still can survive at 70 DEG C and can be metabolized to generate alpha-amylase. The enzyme activity of the alpha-amylase in a fermentation liquid at 55 DEG C can reach 70U/mL.
