Microorganism of producing D-pantothenic acid enternal ester hydrolase and process for preparing D-pantothenic acid thereof

The invention relates to a method used microorganism enzyme resolution DL-pantoic acid lactone to produce D-pantoic acid. It uses the D-pantoic acid lactone hydrolase strain of the fusarium, gibberella, aspergillus, penicillium, rhizopus, gliocladium, aureobasidium to ferment and culture, uses wet thallus as coarse enzyme, DL-pantoic acid lactone as substrate to produce D-pantoic acid. L- pantoic acid lactone can be reclaimed. The DL-pantoic acid lactone gained by racemization reaction can newly be used to do resolution.
