Two new lanostane-type triterpenoids, 3alpha,16alpha-dihydroxylanosta-7,9(11),24-trien-21-oic acid (1) and 3alpha,16alpha,26-trihydroxylanosta-7,9(11),24-trien-21-oic acid (2), along with three known lanostanoids, 16alpha-hydroxy-3-oxolanosta-7,9(11),24-trien-21-oic acid (3), 3alpha-carboxyacetoxy-24-methylen-23-oxolanost-8-en-26-oic acid (4), and 3alpha-carboxyacetoxy-24-methyl-23-oxolanost-8-en-26-oic acid (5), have been isolated from the EtOAc extract of the fruiting body of Ganoderma applanatum. The structures of 1, 2, and 3 were determined directly by the interpretation of spectroscopic data, while the structures of 4 and 5 were assigned by comparison of spectroscopic data against literature values.

A total of 640 one-day-old Cobb 500 MV × Cobb 500 FF mixed broilers were randomly assigned to one of four experimental treatments with four replicates per treatment and 40 birds per replicate for 32 days. The treatments consisted of a basal diet (control group), basal diet + 0.02% zinc bacitracin (AGP group), basal diet + 0.

To obtain an effective bacterial biocontrol strain against the fungal pathogen , causing rubber tree red root rot disease, healthy rubber tree tissue from Baisha County, Hainan Province, was selected as the isolation source, and bacterial strains with strong antifungal effects against . were screened. The strain was identified by molecular biology, in vitro root segment tests, pot growth promotion tests, and genome detection.

Species of the genus Ganoderma are important medicinal and edible mushrooms, with polysaccharides being its main active ingredient. The submerged fermentation of Ganoderma is an important source of polysaccharides in the mycelia. In this study, a single factor test and an orthogonal test were employed to optimize the medium and fermentation conditions with the objective of obtaining a high content of polysaccharide in the liquid submerged fermentation culture mycelia of Ganoderma species.

In our study, four species of wood-decaying fungi with perennial fruiting bodies were used as the source of biologically active compounds (BACs) - Inonotus obliquus (chaga), Fomitopsis pinicola, Fomes fomentarius, and Ganoderma applanatum. Fungi have a wide range of secondary metabolites but are used much less frequently than plants in both folk and official medicine. Fungotherapy could be considered a promising trend in the development of modern natural therapy.
