  • The influences of temperature and nutritional conditions on the mycelium growth of oyster mushroom Pleurotus ostreatus (PO) and Pleurotus cystidiosus (PC) were investigated in laboratory experiment during the summer season of 2014. The results of the experiment indicated that potato dextrose agar (PDA) and yam dextrose agar (YDA) were the most suitable media for the mycelium growth of oyster mushroom PO while four media (PDA, YDA, sweet potato dextrose agar, and malt extract agar medium) were not significantly different in supporting mycelium growth of oyster mushroom PC. The optimal temperature for mycelium growth of both oyster mushroom species was obtained at $28^{\circ}C$. Mycelium growth of oyster mushroom PO was improved by carbon sources such as glucose, molasses, and at 1~5% sucrose concentration, mycelium colony diameter of mushroom PO was achieved the highest value. Whereas glucose, dextrose, and sucrose as carbon sources gave the good mycelium growth of oyster mushroom PC, and at 1~3% sucrose concentration, mycelium colony diameter of PC was achieved the maximum value. Ammonium chloride concentrations at 0.03~0.09% and 0.03~0.05% also gave the greatest values in mycelium colony diameter of mushroom PO and PC. Brown rice was found to be the most favourable for mycelium growth of two oyster mushroom species. In addition, sugarcane residue, acasia sawdust and corn cob were selected as favourable lignocellulosic substrate sources for mycelium growth of both oyster mushrooms.

  • Ergocalciferol은 vitamin D의 활성을 가지는 것으로 알려져 있다. 본 연구에서는 팽이(Flammulina velutipes), 느타리 (Pleurotus ostreatus), 애느타리(Pleurotus ostreatus), 새송이(Pleurotus eryngii), 양송이(Agaricus bisporus), 표고(Lentinula edodes), 목이(Auricularia auricula-judae) 등 7종의 버섯을 대상으로 자외선 조사에 따른 ergocalciferol(EC, 비타민 $D_2$) 함량의 증진 효과를 조사하였다. 자외선을 조사하지 않은 버섯의 ergocalciferol 함량은 극히 낮았으나 자외선 조사에 의해 ergocalciferol 함량이 크게 증가하였으며, 자외선 A, B, C 중 특히 자외선 B가 EC 함량 증진에 효과적이었다. 버섯에서 ergocalciferol의 생성은 자외선에 직접 노출되는 부위 즉 깊이 1 mm 이내의 버섯 표면에서만 일어나는 것으로 조사되었다. 따라서 세절하지 않은 생 버섯에 자외선을 조사할 경우 팽이 버섯과 같이 체적에 비해 표면적인 넓은 종류의 버섯에서 ergocalciferol 생성이 많았고, 건조 및 세절할 경우에는 EC 생성의 기질인 ergosterol의 함량이 높은 버섯에서 ergocalciferol 생성이 많았는데, 새송이, 표고, 양송이 등이 이에 속하였다.

  • Labor required for managing and harvesting the oyster mushroom bed was evaluated. Although vinyl mulching cultivation method needs more hours for spawning, it saves more than 50% of labor for harvesting and managing of the mushroom bed. Harvesting hour of 1st-3rd flush in vinyl mulching method was 48~50% for Plerutus ostreatus and 36~41% for P. sajor-caju. Labor for bed management after harvesting in vinyl mulching method was also 38~50% for P. ostreatus compared to conventional method, and 20~35% for P. sajor-caju. Vinyl mulching is believed to be a very efficient method for saving labor in oyster mushroom cultivation.

  • Breads were prepared from wheat flour supplemented with oyster mushroom (Pleurotus ostreatus) powder, and effects of the supplementation of oyster mushroom powder on dough rheology and bread quality were examined. The initial pasting temperature in viscoamylograph increased, but peak and final viscosities decreased with the increased amount of oyster mushroom powder. The gradual increase of water absorption, dough development time and mixing tolerance index, and decrease of dough stability with the increased amount of oyster mushroom powder were obtained by farinographs. The supplementation of oyster mushroom powder had an effect on the bread making, resulting in an increase of loaf weight and a decrease of loaf volume. The rough and coarse crumb texture with dark color was observed with the increased amount of oyster mushroom powder. The firmness of bread crumb containing oyster mushroom powder was increased during storage periods. Sensory evaluation revealed that the addition of $1\%$ oyster mushroom powder could be supplemented to make an acceptable quality of bread.

  • Mushroom is very important to rural dwellers due to the various economic, health and nutritional benefits that can be derived from its consumption, sales and utilization. Hence, this experiment was carried out with a view to evaluating the influence of locally available substrate i.e., sawdust of different wood species on the cultivation of Pleurotus ostreatus (oyster mushroom). Pleurotus ostreatus was grown on sawdust (indigenous and exotic species) using two pretreatment methods, which included hot water treatment to remove (a water-soluble extract) and non-extracted sawdusts (substrate). The result of this study showed that there was a significant difference in the effect of different wood species selected. Parkia biglobosa produced a better yield (71.06 g), followed by Anogeissus leiocarpus (53.17 g) and Gmelina arborea (51.39 g) in a non-treated unextracted states. In the treated samples, Parkia biglobosa has the highest yield (50.61 g) followed by Anogeissus leiocarpus (49.28 g) and Gmelina arborea (45.00 g). Thus, Parkia biglobosa and Anogeissus leiocarpus produced a higher yield of mushroom either in a treated or non-treated state and they could be recommended for growing oyster mushroom (Pleurotus ostreatus).

  • This study was carried out to storage of Pleurotus ostreatus packed in various trays made by different matrials-expanded polystyrene (EPS), rice straw pulp(RP), and RP trays coated with starch, carboxyl methyl cellulose (CMC), polyacrylamide (PAM), alkylketen dimer (AKD), rosin size (RS) and polyethylene glycol (PEG) at 8~1$0^{\circ}C$ and 70~80% relative hymidity for 6 days. At 6 days storage, weight increase of RP and CMC tray was lower (p<0.05) than those of others and the weight of oyster mushroom packed in RP, CMC and AKD tray decreased lower(p<0.05) than those of others. Carbon dioxide contents in trays were increased from 0.5% to 5.5%~8.6% within 1 day storage. Oxygen contents in trays were sharply decreased from 20% to 0.8%~8.2% within 1 day storage. Lightness of oyster mushroom increased all trays. Off flavor appeared stronly in oyster mushroom packed in EPS, AKD and PEG during storage, but was not detected in mushroom packed in starch and CMC until 4 days storage.

  • The oyster mushroom (Pleurotus ostreatus) is one of the most important edible mushrooms worldwide. The mechanism of P. ostreatus fruiting body development has been of interest both for the basic understanding of the phenotypic change of the mycelium-fruiting body and to improve breeding of the mushrooms. Based on our previous publication of P. ostreatus expressed sequence tag database, 1,528 unigene clones were used in macroarray analysis of mycelium, fruiting body and basidiospore developmental stages of P. ostreatus. Gene expression profile databases generated by evaluating expression levels showed that 33, 10, and 94 genes were abundantly expressed in mycelium, fruiting body and basidiospore developmental stages, respectively. Among them, the genes specifically expressed in the fruiting body stage were further analyzed by reverse transcription-polymerase chain reaction and Northern blot to investigate temporal and spatial expression patterns. These results provide useful information for future studies of edible mushroom development.

  • 버섯 병재배 수확배지를 느타리버섯 2차배지로 재활용하기 위해 팽이버섯, 큰느타리, 느타리 재배후 탈병배지를 운반하여 바로 느타리 532배지에 첨가시험을 수행한 결과, 팽이버섯과 큰느타리 수확후배지를 첨가한 배지에서 느타리 품종 춘추2호와 만추리는 모두 자실체 수량이 무첨가구에 비하여 낮은 경향이었다. 그러나 느타리 병재배 수확후배지는 기본배지에 대하여 50%까지 대체하여도 수량은 증가하는 경향이었으나 10%~30% 첨가수준에서 안정적으로 증수되었다.
