ПРОДУКТИВНІСТЬ ШТАМІВ РОДУ PLEUROTUS НА ЛІГНОЦЕЛЮЛОЗНИХ ВІДХОДАХ ПЕРЕРОБКИ ОЛІЙНИХ КУЛЬТУР

Abstract

The article presents the results of the study of the possibility of obtaining commercial fruit bodies of mushrooms for the cultivation of strains of the genus Pleurotus on lignocellulosic waste from the oil industry. The study of growth rates and fertility was carried out in several stages. The initial stage of the research was the study of indicators of radial growth of mycelium 7 strains of the clay common on a standard KGA. The next stage was the study of basidiomata and found the ability to form fruit bodies of mushrooms in vitro by all of the experimental strains Pleurotus ostreatus . The strains on the wet sunflower husk were first cultivated in complete darkness at a temperature of +26 ± 0.5°C until the substrate was completely overgrown with mycelium (dark phase), after which the flasks were exposed on the rack under the daylight lamp (the intensity of the light was 1500 lux, the temperature – + 22°C) (light phase). The cultivation process was completed after two fungal waves. To determine linear growth, the diameter of the colony was measured. The investigated mushroom was sown to the center of the surface of a dense nutrient medium and measured the diameter in two mutually perpendicular directions in two to three replicates at certain intervals. In the study of the growth of strains Pleurotus ostreatus , the most productive cultures were isolated: P. ostreatus Hk-35 and Pleurotus ostreatus P-192. According to the indices, when growing on moist husk, sunflower leaders are P. ostreatus Hk-35 and wild straw P-192. These strains are promising for the further selection of highly productive industrial crops Pleurotus ostreatus . Key words: Pleurotus ostreatus , mycelium , basidioma , radial height , cultivation.
