毕赤酵母是一种能以甲醇为唯一碳源生长的甲基营养型酵母,常用作表达外源蛋白的细胞工厂。目前毕赤酵母常用的高效启动子AOX1(PAOX1)是一个严格的底物依赖型启动子,受甲醇的严格诱导,受葡萄糖、甘油、乙醇等非甲醇碳源抑制。但是甲醇有... 毕赤酵母是一种能以甲醇为唯一碳源生长的甲基营养型酵母,常用作表达外源蛋白的细胞工厂。目前毕赤酵母常用的高效启动子AOX1(PAOX1)是一个严格的底物依赖型启动子,受甲醇的严格诱导,受葡萄糖、甘油、乙醇等非甲醇碳源抑制。但是甲醇有毒、易燃、易爆的特性使得其在食用、医用产品生产等领域受到很大的限制。本文将主要从PAOX1机制改造、新型启动子和非甲醇诱导物研发的角度阐述毕赤酵母非甲醇诱导的研究进展。 展开更多

From the chemical catalysis viewpoint,the excellent performance of CNTs in adsorption-activation of H2 and in promoting spillover of adsorbed H-species is very attractive,in addition to their nanosize channels,sp2-C constructed surfaces,and high thermal/electrical conductivity.This review examines some recent progresses of CNTs as a novel support or promoter of catalysts for certain hydrogenation or dehydrogenation reactions,e.g.,hydrogenation-conversion of syngas to yield alcohols and decomposition or steam-reforming of methanol to generate H2,mainly based on recent work carried out in our laboratory. 展开更多
