    摘要: The invention relates to a method for the production of xylitol, the method comprising (a1) providing (i) a microorganism having xylanolytic activity, and (ii) a microorganism capable of converting a pentose sugar to xylitol; or (a2) providing a microorganism having xylanolytic activity and being capable of converting a pentose sugar to xylitol, (b) culturing the microorganism of step (a1) (i) or the microorganism of step (a2) in a medium comprising polymer or oligomer materials containing pentose sugars in conditions sufficient for enabling hydrolysis of said polymers or oligomers by the microorganism; (c) producing xylitol in the microorganism of step (a1) (ii) or in the microorganism of step (a2) by bioconversion of the hydrolysis products obtained in step (b), and (d) recovering said xylitol produced. The invention also relates to a microorganism, which has xylanolytic activity and has been genetically modified (i) to enhance its xylanolytic activity, and (ii) to reduce its xylitol metabolism.

    摘要: The present invention relates to a method for producing terpenes in fungi, wherein a terpene biosynthetic gene cluster having terpene biosynthetic genes and regulatory regions operably linked to said genes is activated. The invention relates also to a terpene biosynthetic gene duster and regulatory regions of such terpene biosynthetic gene cluster usable is production of terpenes, use of regulator for regulating the terpene production and use of Aspergillus nidulans FGSC A4 for producing terpenes. The method of invention provides higher yields of enriched terpene product without essential amount of side-products.
