Study on Identification of the Microbial Strain for Transforming Puerariae Radix and Its Microbial
Characteristics

Abstract

Abstract:

A strain of filamentous fungi which was able to transform the active ingredient in Puerariae radix was obtained in microbial
transformation experiments and named YM3207. After observing and analyzing the morphology and ITS sequence of this fungi, it was
identified as Monascus purpureus. HPLC was used to analyze the change of transformation column. The content of Genistein and
Puerarin have been improved. At the same time, antibacterial activity enhanced and antimicrobial spectrum expanded as well.

Key words: Puerariae radix, microbial transformation, identification, antibacterial

CLC Number:

Q939.5：R28
