We compared cold and hot wood extracts of 3 endemic Siberian trees-namely, Prunus padus (bird cherry), Populus tremula (aspen), and Betula sp. (birch)-on biomass production and laccase and peroxidase secretion in submerged cultures by the medicinal mushroom Lentinus edodes. Of the conditions tested, only hot Prunus extracts stimulated biomass production, whereas all extracts stimulated laccase and peroxidase secretion, albeit to different extents. A large, differential stimulation of manganese peroxidase was observed by hot Prunus extracts...

This study pertains to the radical scavenging potential of and DNA protection by Helvella lacunosa, an edible mushroom from Kashmir Himalaya (India). Different solvents, on the basis of their polarities, were used to extract all solvent-soluble bioactive compounds. Seven different antioxidant methods were also used to determine extensive radical scavenging activity. The mushroom ethanol extract and butanol extract showed effective scavenging activity of radicals at 95% and 89%, respectively. At 800 µg/mg, the ethanol extract was potent enough to protect DNA from degradation by hydroxyl radicals...

A new Grifola frondosa mutant, M270, was successfully isolated for high production of exopolysaccharides (EPSs) using cosmic radiation-induced mutagenesis. We found that the mutant M270 had a clearer and thicker EPS layer (~10 µm) adhering to mycelia than those of its parent strain 265 after Congo red staining. In the 20-L batch fermentation for M270, 10.3 g/L of EPS and 17.9 g/L of dry mycelia biomass were obtained after 204 hours of fermentation. Furthermore, a main water-soluble fraction (EP1) in the EPS was purified from M270 and then confirmed to be heteroglycan-protein complex with 91% (w/w) total carbohydrates and 9% (w/w) total proteins...

The objective of this study was to compare the mycochemical profiles, antioxidant activities, and antidiabetic effects of 2 species of genus Ganoderma, the red lingzhi (G. lucidum) and purple lingzhi (G. sinense) mushrooms. In Chinese medicinal practice, hot water and ethanol are used as solvents to extract samples. In this study, a total of 4 extracts (ethanol and hot water extracts from G. lucidum and G. sinense) were prepared for further assays. Hot water extracts presented much higher values for total phenolic content and ferric-reducing antioxidant power than the ethanol extracts...

We investigated the effects of light intensity in the 3 cultivation stages separately-the mycelium colonization stage, the primordial initiation stage, and the fruiting stage (in order)-on fruiting body and bioactive compound production by Cordyceps militaris. In the mycelium colonization stage, rice substrates were incubated in a spawn running room at 23°C. During the primordial initiation stage, C. militaris was grown at 18°C and illuminated 12 hours/day. In the fruiting stage the temperature was 23°C, with illumination provided 12 hours/day...

In modern mycology, the name "Pleurotus sajor-caju" has 2 meanings: a strict taxonomical meaning refers to its nomenclatural synonym Lentinus sajor-caju, and a more widely distributed biotechnological meaning refers to a strain determined as "Pleurotus sajor-caju" but that belongs to true Pleurotus. The main purpose of this article is to highlight the taxonomic status and to give the correct name for this problematic member of Pleurotus. Both microscopic analysis and BLAST search results (internal transcribed spacer homology varies between 97% and 100%) provide the position of the fungus in question into the range of infraspecific radiation of P...

Exopolysaccharide (EPS) production by a strain of Lentinus edodes was studied via the effects of treatments with ultraviolet (UV) irradiation and acridine orange. Furthermore, optimization of EPS production was studied using a genetic algorithm coupled with an artificial neural network in submerged fermentation. Exposure to irradiation and acridine orange resulted in improved EPS production (2.783 and 5.548 g/L, respectively) when compared with the wild strain (1.044 g/L), whereas optimization led to improved productivity (23...

Squalene synthase catalyzes the condensation of 2 molecules of farnesyl diphosphate to produce squalene, the first committed precursor for sterol, brassinosteroid, and triterpene biosynthesis. A squalene synthase gene, designated IoSQS, was isolated from Inonotus obliquus, a medicinal mushroom that produces a plethora of bioactive triterpenes. IoSQS complementary DNA was found to contain an open reading frame of 1476 bp, encoding a protein of 491 amino acids with a calculated molecular mass of 55.85 kDa. The IoSQS genomic DNA sequence consisted of 1813 bp and contained 4 exons and 3 introns...

We investigated the effects of Phellinus linteus extracts (PLEs) against radiation damage in mice. First, BALB/c mice were irradiated once with γ-rays at 4, 5, 6, or 8 Gy and allowed to recover for 20 days. Results reveal that 8-Gy radiation caused death in 100% of mice on day 13, and 6-Gy radiation caused death in 86.7% of mice (13/15) at the end of the experiment, whereas 4- and 5-Gy radiation did not result in any death. We then used 5-Gy γ-ray radiation to examine the protective effects of PLEs. Mice were orally administered a PLE (500, 1000, and 1500 mg/kg) daily for 2 weeks before radiation and for 6 weeks after radiation...

Grifola gargal Singer and Grifola sordulenta (Mont.) Singer mushrooms are related to Grifola frondosa (Dicks.) Gray, which is well known for its medicinal properties. In vitro studies were performed to find a useful guide for optimizing the environmental parameters through biotransformation of lignocellulosic materials and basidiome development, also considering secondary metabolism-related responses (SMRRs) associated with these processes and the variability among species and strains; this optimization is necessary to make the mushroom's industrial cultivation profitable...
