Studies on the Artificial Substrates with Rice Straw and the Spawning for Pleurotus florida in Korea (볏짚을 이용(利用)한 사철느타리버섯의 배지(培地) 제조(製造) 및 종균재식(種菌栽植)에 관한 연구(硏究))

  • This study was performed to examine the cultivation of Pleurotus florida that forms pinhead between 5 and $25^{\circ}C$, on rice straw substrates in Korea. The highest yield of P. florida sporophores was obtained from the fermented rice straw substrates added 5% rice bran to the rice straw by dry weight basis at the starting of fermentation. The pile turning of materials for uniform fermenting was made three times when the temperature of the pile reached $60^{\circ}C$ during out door composting. The $60^{\circ}C$ row steam was treated 6 hrs for pasterization of the substrates in the cultivating house. The quantity of spawn affected the mycelial growth and the yield of P. florida. The optimum amount of spawn was 10% to the rice straw by dry weight basis mixed with the substrates. P. florida produced normal sphorophores from September to middle of July of the following year.

  • The antioxidant activities of Artemisia capillaris and Artemisia iwayomogi used as Injin (Korean herbal name) were investigated. The DPPH radical scavenging activity of the ethylacetate fractions obtained from the Artemisia capillaris and Artemisia iwayomogi was higher than other fractions. No DPPH radical scavenging activity was observed in hexane frcations. The nitrite scavenging activity was the highest at pH 1.2, and the peroxide value for linoleic acid was increased during the incubation.

  • Interspecific heterokaryons were obtained between auxotrophic mutants of Pleurotus ostreatus and Pleurotus florida by polyethylene $glycol-Ca^{++}$ induced fusion of somatic protoplasts. The fusion products produced colonies of dense growing mycelium after 10-14 days culture on hypertonic Mushroom Minimal Medium. When they were transferred to Mushroom Minimal Medium plates, the sectors showed normal vegetative morphology but the colonies of irregular shape varied in growth rate. All of the colonies produced fruit body of normal pilei. Some heterokaryon colonies bearing none or only a small amounts of basidiospores were isolated. Fusion products, generally, gave higher basidiocarp yields than the parents.

  • Transformation of an auxotrophic requirement for uracil in Pleurotus florida P101 has been achieved using chimeric vector containing Aspergillus nidulans ans 1, and Neurospora crassa pyr 4 DNA. Protoplasts of $Ura^-$strains of P. florida were incubated with plasmid pDJB3 containing the cloned pyr 4 gene in the presence of polyethylene glycol and $CaCl_2$. Transformants could grow on MMM showing mitotical stability. Southern hybridization analysis of DNA isolated from transformants showed that the Neurospora pyr 4 gene and vector sequence might be integrated into the P. florida chromosomes. As the transformants were monokaryon, each transformant was mated with the other monokaryon. Fruitbody shape of untransformant was eroded type but those of transformants were eroded type, funnel type, plane type and ungrowing cap type.
