In this study, a Ganoderma lucidum polysaccharide GLP-1-1 was isolated from a culture broth with Mw of 22014 Da. Monosaccharide contained glucose, mannose, and galactose with mole percentages of 92.33%, 7.55%, and 0.22%, respectively. Moreover, FTIR and methylation analysis were conducted to characterize the structural properties of GLP-1-1. The results of antioxidant activity analysis showed that GLP-1-1 had a great DPPH and ABTS radical scavenging activity. Meanwhile, GLP-1-1 also exhibited anti-tumor activity to A431 and MDA-MB-231 cells, and inhibitory rates were dose-dependent. During culturing with GLP-1-1, the G1/G0 cell percentage of A431 cells was increased from 48.64% to 84.52%, and the G1/G0 cell percentage of MDA-MB-231 cells was increased from 57.14% to 73.48%. Therefore, the anti-tumor activity of GLP-1-1 may be caused by inducing the G1/G0 arrest of tumor cells.

Due to their importance in various fields such biotechnology, medicine, food science, preserving microorganisms effectively is essential. This study investigated cryopreservation of the edible fungus Pleurotus pulmonarius and the medicinal mushroom Ganoderma lucidum, for three years at -80°C in sorghum grains without cryoprotectants. We compared viability, growth, and yields with strains maintained on agar media at 5°C.

Gene editing is emerging as a powerful tool for introducing novel functionalities in mushrooms. While CRISPR/Cas9-induced double-strand breaks (DSBs) typically rely on non-homologous end joining (NHEJ) for gene disruption, precise insertion of heterologous DNA in mushrooms is less explored. Here, we evaluated the efficacy of inserting donor DNAs (8-1008 bp) with or without homologous arms at Cas9-gRNA RNP-induced DSBs.

Unlabelled: High temperature is an unavoidable environmental stress that generally exerts detrimental effects on organisms and has widespread effects on metabolism. Spermidine is an important member of the polyamines family and is involved in a range of abiotic stress responses in plants. Mitochondria play an essential role in cellular homeostasis and are key components of the stress response.

Fungi polysaccharides are nutraceutical-rich compounds with bioactive properties, offering promising applications in food formulation. This study examined the non-covalent complexation of commercial polysaccharides derived from the fruiting bodies of (AA) and (GL) and soy protein isolate to enhance emulsifying properties. Complexes were examined across protein-to-polysaccharide ratios (0:1 to 1:0), pH levels (3 to 7), and heat treatment conditions.

is a traditional Chinese medicinal fungus, and ganoderma triterpenoids (GTs) are one of the main bioactive compounds. These compounds have various pharmacological functions, including anti-tumor, antioxidant, anti-inflammatory, liver-protective, and immune-regulating effects. However, the manner in which they accumulate, and their biosynthesis mechanisms remain unclear.
