Hot-water extracts of the mycelial culture and fruiting bodies of Agaricus blazei Murill were fractionated by ethanol precipitation, using various ethanol concentrations. The mycelial fraction (A-4) inhibited abnormal collagen fiber formation, and fractions A-1 to A-3 showed a small inhibitory effect. The strongest inhibition was obtained by fraction A-4, and no significant inhibition was obser...

Antibacterial activity of Lentinula edodes against Bacillus subtilis was evaluated in cell-free filtrates obtained after growth in 14 different culture media. The highest B. subtilis growth inhibition was promoted by filtrates of growth media supplemented with rice bran, vermiculite or molasses. L. edodes dry mycelial biomass in liquid culture with 0.5% added rice bran was 3.2 mg/ml, after grow...

Schizophyllum commune a Nigeria edible higher fungus is valued for its high nutritional composition. The major limitation to its availability and utilization is that it is seasonal in nature. The fungus was obtained from dead wood and maintained on potato dextrose agar supplemented with 0.5% peptone. We observed the effects of temperature, pH, vitamins and carbon source on the vegetative growth...

Abstract Office and retail interior fittings have a relatively short service life of 5-7 years. In this context, composite materials are often used, hindering possibilities reuse or recycling. This research explores novel bio-composite subsequently construction method for CO 2 -neutral, circular office spaces. Based on the potential fungal mycelium as rapidly renewable, regenerative, affordable...

Carbonell, Luis M. (Instituto Venezolano de Investigaciones Científicas, Caracas, Venezuela), and Joaquín Rodríguez. Transformation of mycelial and yeast forms of Paracoccidioides brasiliensis in cultures and in experimental inoculations. J. Bacteriol. 90:504-510. 1965.-Experimental transformations of mycelial to yeast and yeast to mycelial forms in culture, and mycelial to yeast forms in tissu...

ABSTRACT The in vitro effects of a red pine phenolic compound (pinosylvin), a phenolic compound common to other species (tannic acid), and the major red pine monoterpenes (alpha-pinene, beta-pinene, and delta-3-carene) on spore germination and mycelial growth of Sphaeropsis sapinea were examined. Two A and two B morphotype isolates were used. At 88 mug/mm(2), pinosylvin inhibited spore germinat...

The oomycete vegetable pathogen Phytophthora capsici causes significant losses of important vegetable crops worldwide. Calcium and other plant nutrients have been used in disease management of oomycete pathogens. Calcium homeostasis and signaling is essential for numerous biological processes, and Ca(2+) channel blockers prevent excessive Ca(2+) influx into the fungal cell. However, it is not k...

The optical density ( 450 nm) of samples of homogenized fungal biomass correlated linearly with the dry weight of the biomass in the samples. As shown for broths of the filamentous microfungus Neurospora sitophila, the sensitivity of the technique depended on the extent of fragmentation of fungal hyphae during homogenization: increased fragmentation increased sensitivity. The method applied dur...

Pistachio nut is a strategic product throughout the world, especially in Iran. There are some problems that reduce production and export of pistachios, for example, postharvest fungi, especially Aspergillus spp., that lead to production of mycotoxins. Nowadays the use of chemical and synthetic antifungals is discouraged and reduced because of health risks to mankind and nature. In present study...

Paracoccidioides brasiliensis, the etiologic agent of paracoccidioidomycosis, causes disease much more frequently in men than it does in women, suggesting that the hormonal milieu of the host might influence P. brasiliensis pathogenicity. We recently demonstrated that cytosol from yeast cultures of P. brasiliensis contains a high-affinity, low-capacity, tritiated 17 beta-estradiol [( 3H]estradi...
