The micro and macronutrient content of Pleurotus ostreatus cultivated on different woody substrates viz; Pycnanthus ongoleubis, Ceiba pentandra and Cananium sp. was investigated. Mineral analysis revealed that phosphorus had the highest value in all the minerals sampled and it value ranges between 51.97 mg/100 g to 56.77 mg/100 g while Magnesium recorded the least value of 1.69 mg/100g to 3.57 ...

The present study aimed to determine the antitumor effects of polysaccharides extracted from Pleurotus ostreatus mycelium on gastric cancer in vitro and in vivo. Polysaccharides were extracted from Pleurotus ostreatus mycelium and an antitumor component, known as Pleurotus ostreatus mycelium polysaccharides 2 (POMP2), with a relative molecular weight of 29 kDa, was then sequentially purified us...

Pleurotus species secrete phenol oxidase enzymes: laccase (Lcc) and manganese peroxidase (MnP). New genotypes of these species show potential to be used in processes aiming at the degradation of phenolic compounds, polycyclic aromatic hydrocarbons and dyes. Hence, a screening of some strains of Pleurotus towards Lcc and MnP production was performed in this work. Ten strains were grown through s...

The extracellular polysaccharides produced by sorne fungi involved in the deterioratlon of wood (Pleurotus species) and stone (Ulocladium atrum) were isolated and characterized. Both are 13-0 ..... 3)-linked glucans with considerable branching degree, as revealed by methylation analysis and 13C-NMR. The Pleurotus glucans present the most complex structure and the study was followed by the analy...

The effect of atrazine concentrations on mycelial growth and ligninolytic enzyme activities of eight native ligninolytic macrofungi isolated in Veracruz, México, were evaluated in a semi-solid culture medium. Inhibition of mycelial growth and growth rates were significantly affected (p=0.05) by atrazine concentrations (468, 937, 1875, and 3750 mg/l). In accordance with the median effective conc...

Interspecific hybrids of Pleurotus florida PF-5 (MTCC 1801) and Pleurotus sajor-caju PSC3 (ATCC 62887) were developed using electrofusion. A concentration of 2mM vanillin and 1000ppm carbendazim were selected as screening markers for the hybrids of the two Pleurotus spp. The electrofusion using an exponential decay was best with 1000 V (2 pulses with an interval of 5 sec). With square wave disc...

the rate and efficiency of decolorization of dyes likeblue ca, black b133, and corazol violet sr were tested to evaluate white rot fungal strains. trametes hirsuta and pleurotus florida showed the greatest extent ofdecolorization on nutrient salt media. maximum decolorization of 200 mg/l of blue 133 was obtained by 4days old incubated pleurotus florida followed bytrametes hirsuta after 6 days. ...

Pleurotus sajor caju spawns prepared, yield fruiting bodies, Aqueous extract of these was used to test for inhibitory against Tobacco Mosaic Virus. Infectivity assay (locallesion) method was employed for the anti-viral activity. Treatments, on host plants, were distributed using half-leaf method. The results indicated that extract of the edible mushroom showed anti-viral property.

Various bacteria were isolated from the casing layer soil of the culture bed of P. ostreatus and their role in fruiting body induction of the edible mushroom, P. ostreatus, was investigated. Analysis of the bacterial community isolated from the casing layer soil revealed that the composition of genera and number of cultivable bacteria were different for each sterilizing treatment. Bordetella wa...
