Abstract Oyster mushroom (Pleurotus ostreatus) is fleshy, edible fungi and used throughout the world. Among the most well-known species of mushrooms, Pleurotus sp. is the third most popularly grown mushroom in the world and rank second in India. The most well-known species of Pleurotus are P. ostreatus, P. florida, P. eryngii, P. cystidiosis, P. flabellatus, P. cornucopie, and P. sajor-caju. According to the morphological, molecular character and ITS sequencing, the Pleurotus ostreatus was distinguish from the other species. The cap (pileus) of the oyster mushroom has whitish to grey color and fleshy. Stipe cream and smooth surface. Spores are whitish to lilac grey in mass, cylindrical to oblong shape. Spore print was white in color. Whitish mycelium growth in PDA plate. The ITS sequence was submitted to gene bank NCBI and it was accepted by NCBI with accession number MW446165.

The allelopathy of spent substrate extracts including water extract and ethanol extract ofPleurotus ostreatuson the mycelium growth of six edible fungi, i.e.Flammulina velutipes,Ganoderma lucidum Karst,Pleurotus ostreatusandCordyceps (three species), were investigated using Petri dishes approach. The results indicated that the spent substrate extracts have different effects on their mycelium growth. The mycelium ofFlammulina velutipesgrows better than control check with increasing water extract concentration. The mycelia ofGanoderma lucidum Karstgrow first promotion after inhibition with increasing water extract concentration. The mycelia ofFlammulina velutipes, Ganoderma lucidum Karst, Pleurotus ostreatusare promoted by ethanol extracts. The mycelia of Cordyceps (three species) grow first promotion after inhibition with ethanol extracts. The results can provide reference values for rational utilization of the spent mushroom substrate.

This research aims to determine the effect of concentrations and the intervals of watering of coconut water on the growth and yields of white oyster mushroom. This research was carried out at Saree UPTD Horticulture Seed Centre, Aceh Besar regency from Mei to July 2018. The research units were compiled based on a Completely Randomized Design-factorial  4x4 with 3 replications and continued with Honestly Significance Difference test (Turkey test) level of 5% on a significant F test result. The first factors were the concentrations of coconut water  : 0, 25, 50, and 75 %. The second factors were the interval of watering: once a day, twice a day, three times a day and four times a day. The result of the research showed that the concentrations of coconut water treatment were highly significant on initial growth of mycelium,  mushroom hood diameter, the number of mushrooms, mushroom fresh weight per baglog and mushroom fresh weight for 3 times harvest and it was not significant on the rate of mycelium growth and long fruit hood stalk. 50% concentration of coconut water treatment gives the best result on the growth and yield. The intervals of watering  of coconut water was highly significant on mushroom hood diameter, the number of mushrooms, mushroom fresh weight per baglog and mushroom fresh weight for 3 times harvest and they significant on long fruit hood stalk and not significant on initial growth of mycelium, the rate of mycelium growth and the number of mushrooms. The interval of watering twice a day treatment shows the best result on the growth and yields of white oyster mushroom. The interaction of concentrations of coconut water and the interval of watering was significant on mushroom hood diameter. 50% concentration of coconut water and the interval of watering twice a day shows the best result on growth and yields of white oyster mushroom.

<p class="HowToCite"><em>The waste of tea powder is abundant and has not been widely used optimally. The alternative use is to use the waste as an additional medium or substitution for the white oyster mushroom growing media. The purpose of the study was to determine the effect of mycelium growth and the production of the fruit of the white oyster mushroom on combination media / tea powder substitution with sawdust. The research design used was a completely randomized design (CRD) with 4 replications. Combined treatments were M0 = 100% sawdust; M1 = 100% Tea waste powder; M2 = 75% tea powder + 25% sawdust; M3 = 50% tea powder + 50% sawdust and M4 = 25% tea powder + 75% sawdust. All treatments used the composition of the manufacture of mushroom growing media consisting of each combination of treatments, bran 10% by weight of the material and lime 0.5% by weight of the material. The parameters observed were the growth of white oyster mushroom mycelium, the rate of mycelium growth, the time the mycelium closed the substrate, the time of appearance of the fruiting body, the weight of the fruit body and the diameter of the fruit hood. The results showed that all parameters differed significantly. The best treatment is in treatment M4, followed by treatment of M3, M0 and M2.</em></p>

Food safety is a very frequent topic. The article deals with the problems of fortification of the most grown mushroom in Slovakia, and the 3rd most grown mushroom in the world, Pleurotus ostreatus. Due to the high environmental pollution of soils and air, there is a risk of the production of dangerous fruiting bodies with high heavy metals content. It is known that these substances can promote serious health effects on human body, such as bone weakness or kidney damages (cadmium) and negative process of cognitive developing (lead). The experiment was focused on biofortification with selenium to reduce the accumulation of selected heavy metals (lead, cadmium) in oyster mushroom, grown with intensive cultivation under artificial conditions. This work confirms that the application of sodium selenate to the growing substrate with straw as the main component can reduce the accumulation of cadmium (by 22.45%) and lead (by 64.81%). Research by various authors reported the ability of the oyster mushroom to embed selenium from the substrate into the fruiting bodies. Based on the results of the experiments, we propose to fortify the growing substrate for the production of oyster mushroom by selenium. This way we produce a food with a high antioxidant potential.

Abstract The study aimed to find alternative substrates for growing spawn of oyster mushroom (Pleurotus ostreatus). The experiment was laid out in a completely randomized design with three compositions of substrates. The substrate compositions were: (1) Substrate A (corn 100%), (2) Substrate B (corn and sawdust mix in a ratio of (1:1, v/v)), and (3) Substrate C (corn and sawdust mix in a ratio of (3:1, v/v)). All compositions were replicated 18 times. The complete colonization (days) and mycelium growth rate (cm day−1) were recorded. Means were analyzed by Analysis of Variance (ANOVA) and duncan test was performed if there were significant between the substrate compositions. The results showed that substrate C was the best substrate indicated with the fastest complete colonization of 14.17±0.92 and the highest growth rate of 0.85±0.06 cm day−1.

Abstract Wet sparging grain, a waste product of brewery, was shown to be successfully utilized as a supplement to the nutrient media and substrates for both isolation of the vegetative mycelium of the Pleurotus ostreatus mushroom, as well as for its further recovery and growing the carposomes. We studied the influence of the wet sparging grain on mycelium growth. Cultivation results demonstrated that wet sparging grain is an efficient additional component to the minimal agarized nutrient media for P. ostreatus growth and isolation and to its common fruit body cultivation substrates. Even the depleted agaric media and substrates with addition of the sparging grain allowed intensive growth of the P. ostreatus mycelium and its fructifying. Practical Application: Addition of wet sparging grain to poor cheap substrates increases their quality for rearing the edible oyster mushroom mycelium to the level of reach substrates, and allows utilization of agricultural wastes. The technique is ready for application and patented in the Russian Federation.
