AbstractExtracts of the fruiting bodies of the Oyster mushroom (Pleurotus ostreatus) grown on wood substrates (beech, oak, linden, walnut, poplar) and extracts of the fruiting bodies of the Oyster mushroom (Pleurotus pulmonarius) grown in nature on aspen wood were used to determine the total phenols, total flavonoids, lycopene and β-carotene. The content of individual antioxidants varies considerably depending, not only on the substrate, but also on the extracting agents. The highest content of total phenols and total flavonoids was found in methanol and water extracts of the fruiting bodies of the Oyster mushrooms grown on oak and linden substrates. The maximum content of lycopene and β-carotene was determined in acetone and n-hexane (ratio 4 : 6) extracts of the fruiting bodies of the Oyster mushroom grown on an oak block. The results obtained in this study demonstrated that the quantitative and also probably the qualitative composition of the antioxidants in the fruiting bodies of Oyster mushrooms depended considerably on the substrate composition.

In this study, grey oyster mushroom (Pleurotus pulmonarius) was cultivated in indoor controlled environment to seeking out the possible Risks of contamination and ways of treatment to avoid the contamination. For this, mushroom was cultivated in providing artificial humidifying and Ventilation system to ensure optimum humidity (80-90%) and fresh air Recirculation in different ways of treatment. The ways of treatment were Included as in position of humidifier, frequency of humidifying, plastic Cork of bags opening part and cleaning of humidifier water container. Maximum percentages of bag contamination (2.5-25.30%), cap Contamination (5.6-30.75%), stalk contamination (4.75-23.25%) and root Contamination (2.6-18.45%) were found in front to front humidifier Position, long humidifying with long interval frequency, without plastic Cork, without cleaning and bi- monthly cleaning of humidifier water Container treatment but no diseases and pest infection was found. Whereas, Very low percentages of contamination (0.1-0.5%) were found in Surrounding humidifying position, short humidifying duration with short Interval frequency, with plastic cork and weekly cleaning of humidifier Water container treatment.

Mating Compatibility

Mating compatibility studies using strains from 170 North American collections in the Pleurotus ostreatus complex reveal three intersterile species of oyster mushrooms in the United States and Canada. Initial pairings among monokaryotic single spore isolates were performed to determine the number of intersterile groups. Dikaryon – monokaryon pairings using monokaryotic tester strains were then used to screen additional dikaryotic cultures of the oyster mushroom. Pairings of tester strains from Europe indicate that two European taxa, P. ostreatus and Pleurotus pulmonarius, are also widely distributed in North America. A third intersterility group occurring primarily on aspen in North America was intersterile with all other known species, and is described as a new species, Pleurotus populinus. All three species differ from one another in their morphology, growth characteristics, geographic distributions, and host ranges. Other than mating compatibility tests, however, no single type of character was found to be completely reliable for distinguishing these species in the field or under laboratory conditions. Furthermore, morphological characters used to distinguish European species of the P. ostreatus complex were not useful when applied to corresponding mating-compatible groups from North America. Key words: oyster mushroom, species concept, mating incompatibility.

Abstract Pleurotus mushrooms are among the most cultivated fungi in the world and are highly valuable for food, medicine, and biotechnology industries. Furthermore, Pleurotus species are carnivorous fungi; they can rapidly paralyze and kill nematodes when nutrient-deprived. The predator–prey interactions between Pleurotus and nematodes are still widely unexplored. Moreover, the molecular mechanisms and the genes involved in the carnivorous behavior of Pleurotus mushrooms remain a mystery. We are attempting to understand the interactions between Pleurotus mushrooms and their nematode prey through genetic and genomic analyses. Two single spores (ss2 and ss5) isolated from a fruiting body of Pleurotus pulmonarius exhibited significant differences in growth and toxicity against nematodes. Thus, using PacBio long reads, we assembled and annotated two high-quality genomes for these two isolates of P. pulmonarius. Each of these assemblies contains 23 scaffolds, including 6 (ss2) and 8 (ss5) telomere-to-telomere scaffolds, and they are among the most complete assembled genomes of the Pleurotus species. Comparative analyses identified the genomic differences between the two P. pulmonarius strains. In sum, this work provides a genomic resource that will be invaluable for better understanding the Italian oyster mushroom P. pulmonarius.
