Abstract: The present invention discloses a Mycobacterium neoaurum-derived steroid C27-monooxygenase and an application thereof, which belong to the technical fields of genetic engineering and enzyme engineering. By the method of gene knockout and intensive expression, the present invention screens out three isoenzymes of a key enzyme SMO in the process of degrading sterol side chains from Mycobacterium neoaurum. The three isoenzymes are intensively expressed respectively in the Mycobacterium neoaurum for the high yield of androsta-1,4-diene-3,17-dione (ADD), the yield of ADD is increased remarkably, wherein the effect of SMO2 is most remarkable. By overexpressing SMO2, the final ADD yield is increased from 5.2 g·L?1 to 7.3 g·L?1. The present invention provides a helpful guidance for the industrialization of the microbial fermentation method for increasing the ADD yield.

Abstract: An inositol preparation method by enzymatic catalysis uses starch and cellulose or substrates thereof as substrates. Raw materials are converted to inositol by in vitro multi-enzyme reaction system in one pot. The yield from the substrate to inositol is significantly improved by process optimization and adding new enzymes. The new enzymes can promote the phosphorolysis of starch or cellulose and utilization of glucose, which is the final production after the phosphorolysis of starch and cellulose. The inositol preparation method described herein has great potentials in industrial production of inositol because of high inositol yield, easy scale-up, low production cost, and lower impact to environment.
