New sesquiterpenes, hirsutenols D-F, were isolated from the fermentation broth of Stereum hirsutum, and their structures were determined on the basis of various spectroscopic analyses. Hirsutenols E and F showed significant scavenging activity against superoxide anion radicals with EC50 values of 1.62 and 0.39 mM, respectively.

In our preview research, four novel quaternary ammonium hybrids were isolated from the FP-91666. To further discover this type of compounds, was fermented in 30 L YMG broth, and eight hybrid compounds including four new quaternary ammoniums were obtained, which are sesquiterpenes combined with α-amino acids. Their structures were elucidated by extensive spectroscopic analyses, including 1D- and 2D-NMR, and HR-MS experiments.

The production of three ligninolytic enzymes, laccase (LAC), manganese peroxidase (MnP) and lignin peroxidase (LiP) by the white-rot fungus, , was significantly more in Koroljova liquid medium in the presence of chlorpyrifos under shaking conditions than under stationary conditions. These enzymes were secreted into the broth to the extent of 214.37, 82.

The mushroom Stereum hirsutum is parasitized by Tremella aurantia to form a heterogeneous basidiocarp Jin'er, which has been used as food and folk medicine in Chinese society. In present work, the S. hirsutum was fermented in YMG broth, and four novel mixed terpenes, stereumamides A-D (1-4), which are sesquiterpenes combined with α-amino acids to form quaternary ammonium hybrids, were isolated from the Stereum hirsutum FP-91666 and their structures were elucidated by spectroscopic data analysis.

Ostalactones A-C (1-3), three new β- and ε-lactone natural products, were isolated from the culture broth of the basidiomycete Stereum ostrea. The structures were elucidated by interpretation of HRFABMS and 1D and 2D NMR data. The structures of 1 and 2 are characterized by the presence of a β-lactone containing a fused 4/5 bicyclic core structure.
