Description
技术领域
本发明涉及生物工程技术领域,尤其是涉及一株重组米曲霉菌株及其曲酸发酵方法。
背景技术
曲酸是一种重要的有机酸。曲酸在食品工业、化妆品、卫生、纺织业、禽畜生产、化工、医药、环保等领域都有十分广阔的应用。目前曲酸的工业应用正在被更多地开发和研究,市场需求以每年5-7%递增,未来也将会具有更加广阔的市场前景。
米曲霉作为重要的曲酸发酵菌株拥有良好的发酵特性。以葡萄糖为发酵原料时,米曲霉可利用葡萄糖直接发酵生成曲酸,而不必破坏葡萄糖的碳骨架。米曲霉是一种曲酸发酵的重要菌株,对米曲霉菌株CGMCC3.042进行基因工程改造是提高曲酸发酵水平的重要手段,而米曲霉对多种真菌常用抗性不敏感,因而常用营养缺陷作为标记。
曲酸是由米曲霉分泌的一种次级代谢产物,受多种转录调控因子调控,其中laeA基因,曲酸合成基因簇内kojA,kojR,kojT基因,在米曲霉中可以显著正调控其次级代谢产物的生成,葡萄糖-6-磷酸脱氢酶是戊糖磷酸途径的关键酶,对糖次级代谢必不可少,而msn2基因敲除菌株曲酸产量也会有所提高。
