Butyrate, a small fatty acid, has an important role in the colon of ruminants and mammalians including the inhibition of inflammation and the regulation of cell proliferation. There is also growing evidence that butyrate is influencing the histone structure in mammalian cells by inhibition of histone deacetylation. Butyrate shows furthermore an antimicrobial activity against fungi, yeast and bacteria, which is linked to its toxicity at a high concentration. In fungi there are indications that butyrate induces the production of secondary metabolites potentially via inhibition of histone deacetylases...

White rot fungi (WRF) are applicable to biodegradation of recalcitrant pollutants. However, excessive biomass growth typical for WRF cultivation can hinder their large scale applications. Therefore, immobilization of Irpex lacteus to liquid-core alginate beads restricting excessive mycelium growth and simultaneously keeping high degradation rate of pollutants was tested. Effective diffusivities of dyes to the beads varied from (2.98 ± 0.69) × 10(-10) to (10.27 ± 2.60) × 10(-10) m(2)/s. Remazol Brilliant Blue R (RBBR), Reactive Orange 16 (RO16), and Naphthol Blue Black (NBB) were used as model dyes...

Thioacetamide (TAA), usually used as a fungicide to control the decay of citrus products, itself is not toxic to the liver, but its intermediates are able to increase oxidative stress in livers and further cause fibrosis. Ophiocordyceps sinensis mycelium (OSM) which contains 10% polysaccharides and 0.25% adenosine decreased (P < 0.05) the lipid accumulation and increased (P < 0.05) antioxidative capacity in livers of thioacetamide (TAA) injected rats. Meanwhile, the increased (P < 0.05) liver sizes, serum alanine transaminase (AST) and aspartate transaminase (ALT) values in thioacetamide (TAA)-injected rats were ameliorated (P < 0...

Acute lung injury (ALI) is characterized by inflammation of the lung tissue and oxidative injury caused by excessive accumulation of reactive oxygen species. Studies have suggested that anti-inflammatory or antioxidant agents could be used for the treatment of ALI with a good outcome. Therefore, our study aimed to test whether the mycelium extract of Sanghuangporus sanghuang (SS-1), believed to exhibit antioxidant and anti-inflammatory properties, could be used against the excessive inflammatory response associated with lipopolysaccharides (LPS)-induced ALI in mice and to investigate its possible mechanism of action...

The Magnaporthe oryzae genes FLB3 and FLB4, orthologues of the Aspergillus nidulans regulators of conidiation FlbC and FlbD, were inactivated. These genes encode C2H2 zinc finger and Myb-like transcription factors, respectively, in A. nidulans. Analysis of the resultant mutants demonstrated that FLB4 is essential for spore formation and that strains lacking this gene are fluffy in their colony morphology due to an inability to complete conidiophore formation. Meanwhile, FLB3 is required for normal levels of aerial mycelium formation...

There are numerous aspects related to Tuber species, which have not been explored to date. Tuber aestivum Vitt. is an ectomycorrhizal fungus, that produces an area (called brûlé) around the host plant trunk, where the germination of other plants is inhibited. What happens inside this particular environment is still not sufficiently understood, especially in terms of soil fauna. A previous work showed that there were higher microarthropod abundances outside during the period of maximum activity of the mycelium...

The oomycete class includes pathogens of animals and plants which are responsible for some of the most significant global losses in agriculture and aquaculture. There is a need to replace traditional chemical means of controlling oomycete growth with more targeted approaches, and the inhibition of sterol synthesis is one promising area. To better direct these efforts, we have studied sterol acquisition in two model organisms: the sterol-autotrophic Saprolegnia parasitica, and the sterol-heterotrophic Phytophthora infestans...
