Genome-Based Analysis of Aspergillus niger Aggregate Species from China and Their Potential for Fumonisin B and Ochratoxin A Production.

Based on entire genome sequencing, this study focused on the classification of Aspergillus niger aggregation species and investigated their potential for fumonisin B (FB) and ochratoxin A (OTA) production. In the current study, 22 strains were used, namely 17 A. niger strains, four A.

Mucor rongii sp. nov., a New Cold-Tolerant Species from China.

Two strains of a new mucoralean fungus (M1 and R1) were harvested from the moist walls of Sufu workshop in Liaocheng city, Shandong province, China. Internal transcribed spacer (ITS) and the large subunit (LSU) rDNA region D1/D2 domain-based phylogenetic analysis, along with phenotypic characteristics, revealed that the strains belonged to a new genus in the Mucor category. This new category belongs to Mucor flavus complex.

Extraction and antioxidant activity of total triterpenoids in the mycelium of a medicinal fungus, Sanghuangporus sanghuang.

The scientific name of the traditional Chinese medicinal fungus, Sanghuang, has been clarified and confirmed that it is a new species -Sanghuangporus sanghuang in the recently discovered genus, Sanghuangporus. To maximize the yield of the active ingredients such as the triterpenoids from authentic Sanghuangporus sanghuang, four parameters of the extraction process, including the extraction time, solid-liquid ratio, extraction temperature, and ethanol concentration were determined. The Box-Behnken experimental design and the response surface method were used to optimize the triterpenoid extraction processes of Sanghuangporus sanghuang mycelium.
