Analysis of Lovastatin-Producing Ability of Fungi in Pu-erh Tea

doi:10.7506/spkx1002-6630-201212034

Abstract

Abstract: The pure strains of Aspergillus, Penicillium and Trichoderma isolated from Pu-erh tea were cultured individually to analyze their ability to produce lovastatin by HPLC. The results showed that only one strain of A. tubingensis, one strain of A. wenti and one strain of A. fumigatus among the genera of Aspergillus had the ability to synthesize lovastatin with the content of 9.59, 2.33 ng/g and 2.77 ng/g, respectively, after culture in the Czapek Yeast Agar (CYA) medium. On the CYA medium, only P. chrysogenum revealed the ability to secrete lovastatin with the content of 3.36 ng/g. Two strains of Trichoderma (T. asperellum and T. citrinoviride) from Pu-erh tea samples had the ability to produce lovastatin with the content of 4.8 ng/g and 1.47 ng/g on the CYA medium, respectively.

Key words: Pu-erh tea, lovastatin, fungi
