Isolation, Identification and Growth Characteristics of a Penicillium Strain Producing Feruloyl Esterases
一株产阿魏酸酯酶青霉菌株的筛选、鉴定及生长特征

The strain HDFE1, producing feruloyl esterases, was isolated from rotten wood fiber. It was identified as Penicillium citrinum Thom by study of morphology and rDNA ITS1-5.8S-ITS2 sequence and phylogenetic analysis. The optimum conditions for its growth were pH 6.0 and 30oC. At 30oC, pH 6.0, and 200 r/min for 60 h, the strain could produce feruloyl esterases at a yield 25 of 20.75 U/L.
