Schizophyllum commune VE_07 was produced in different culture media containing pine sawdust (PS), grape residue (GR), cotton cake (CC) and jatropha seed cake (JC). The content of phenolics and antioxidant activity were determined for the substrates and mushrooms produced. The content of ß-glucans and the composition of S. commune were also evaluated. The medium formulated with 94% grape residue enabled the highest values of yield, biological efficiency, and productivity. Mushrooms grown in this condition showed the highest value (13.14%) of ß-glucans. The contents of proteins and dietary fibre were 16.59% and 59.61%, respectively. Mushrooms grown in cotton cake showed the highest phenolic content (291.51 ± 1.83 mg GAE/ 100 g mushroom) and antioxidant activity (58.15 ± 0.86 DPPH % scavenging). The results obtained indicate that substrate composition affected the production of S. commune and its chemical composition.

is one of the widely produced edible fungi worldwide. It is rich in γ-aminobutyric acid (GABA), a non-protein amino acid with important physiological functions in humans. To investigate the functions of key genes in the GABA metabolic pathway of , we isolated the monokaryon from the factory-cultivated strain and then sequenced and assembled the genome using the PacBio Sequel and Illumina NovaSeq sequencing platforms.

College of Plant Protection, Biocontrol Engineering Laboratory of Crop Diseases and Pests of Gansu Province, Gansu Agricultural University, Lanzhou, China.

Article Synopsis
  • Lily bulb rot disease has caused significant yield losses in edible lilies in China, necessitating a combination of morphological and molecular methods for diagnosis.
  • During the study, a specific strain causing rot was isolated from affected bulbs in Lanzhou, confirming its pathogenicity with 100% effectiveness in causing rot symptoms.
  • The pathogen was identified based on its distinct morphological features and genetic analysis, marking the first documented case of this disease affecting edible lilies in China and offering insights for developing better control strategies.

Fungal Methane Production Under High Hydrostatic Pressure in Deep Subseafloor Sediments.

Microorganisms

October 2024

State Key Laboratory of Pharmaceutical Biotechnology, Nanjing University, Nanjing 210023, China.

Fungi inhabiting deep subseafloor sediments have been shown to possess anaerobic methane (CH) production capabilities under atmospheric conditions. However, their ability to produce CH under in situ conditions with high hydrostatic pressure (HHP) remains unclear. Here, 20R-7-F01, isolated from ~2 km below the seafloor, was cultured in Seawater Medium (SM) in culture bottles fitted with sterile syringes for pressure equilibration.

Image Analysis Characterizes Phenotypic Variation in the Growth of Mushroom-Forming Fungus Schizophyllum commune.

Genes Cells

January 2025

Department of Botany, National Museum of Nature and Science (Kahaku), Tsukuba, Japan.

Schizophyllum commune, a common wood-decay mushroom known for its extremely high genetic variation and as a rare cause of human respiratory diseases, could be a promising model fungus contributing to both biology and medicine. To better understand its phenotypic variation, we developed an image analysis system that quantifies morphological and physiological traits of mycelial colonies in Petri dishes. This study evaluated growth of six wild and one clinical isolates of Japanese S.
