        Thermophile mushroom cultivation in Cambodia: Spawn production and development of a new substrate, acacia tree sawdust

        Hyun-You Chang,Youn-ju Huh,Pisey Soeun,Seung-ho Lee,Iva Song,Reaksmey Sophatt,Geum-Hui Seo 한국버섯학회 2016 한국버섯학회지 Vol.14 No.1

        To minimize cultivation costs, prevent insect-pest infestation, and improve the production efficiency of thermophilic mushrooms, plant substrates obtainedfrom local areas in Cambodia were used for production of both spawn and mushrooms. In this experiment, different sawdusts different organic wastes and grain ingredients and analyzed for improvement of spawnproduction efficiency. Four thermophilic mushroom species, Pleurotus sajor-caju (oyster mushroom, Sambok), Ganoderma lucidum (deer horn shaped), Auricularia auricula (ear mushroom), and Lentinula edodes (shiitake), were used to identify efficient new substrates for spawn and mushroom production. Although the mycelia in the rubber tree sawdust medium showed a slightly slower growth rate (10.9 cm/15 days) than mycelia grown in grains (11.2 cm/15 days in rice seeds), rubber tree sawdust appeared to be an adequate replacement for grain spawn substrates. Th findings indicate that rubber tree sawdust, sugarcane bagasse, and acaciatree sawdust supplemented with rice bran and calcium carbonate could be new alternative the substrates for . Although sugarcane bagasse and rubber tree sawdust showed similarly high biological efficiencies (BE) of 60% and 60.8%, respectively, acacia tree sawdust exhibited relatively a low biological efficiency of 22.4%. However, it is expected that acacia sawdust has potential for the mushroom cultivation when supplemented with currently used sawdust substrates in Cambodia, because of its relatively low price. The price of the sawdust (20 kg sawdust= 6500 Riel or 1.6 USD) currently used was 6.5 times higher than the price of acacia sawdust (201000 Riel or 0.25 )USD). Therefore, utilization for acacia sawdust for mushroom cultivation could become feasible as it would reduce by producing costs of mushrooms in rural areas of Cambodia.

        Thermophile mushroom cultivation in Cambodia: Spawn production and development of a new substrate, acacia tree sawdust

        Chang, Hyun-You,Huh, Youn-ju,Soeun, Pisey,Lee, Seung-ho,Song, Iva,Sophatt, Reaksmey,Seo, Geum-Hui The Korean Society of Mushroom Science 2016 한국버섯학회지 Vol.14 No.1

        이 연구는, 느타리버섯과 풀버섯만 재배하던 캄보디아에서 영지버섯, 목이버섯 그리고 표고버섯 등과 같은 여러 종류의 고온성 버섯들의 종균을 생산하고, 캄보디아에서 생산되는 경제적이고 효율적인 새로운 버섯배지를 찾기 위해 시도되었다. 종균 및 버섯재배 배지로, 여러 종류의 유기물찌꺼기, 곡물, 그리고 톱밥이 사용되었다. 고무나무 톱밥배지에서 자란 균사 (10.9 cm/15일)는 곡물배지에서 자란 균사 (11.2 cm/15일)에 비해 성장이 조금 느렸지만, 고무나무 톱밥은 낮은 가격 및 취급의 용이성이 있어, 비싼 곡물종균을 대치할 수 있는 매우 적절한 배지인 것으로 나타났다. 버섯생산을 위해서, 고무나무톱밥(60.8% BE), 사탕수수박(60% BE), 그리고 아카시아나무 톱밥 등에 미강과 탄산칼슘을 혼합하여 사용하였는데, 사탕수수박과 고무나무 톱밥은 매우 비슷한 높은 생물학적 효율(BE)을 보여주었고, 아카시아나무 톱밥은 비교적 낮은 22.4%의 생물학적 효율을 보여주었다. 따라서 낮은 가격에 구입할 수 있는 아카시아톱밥이 현재 사용되고 있는 높은 가격의 배지들과 혼합하여 사용된다면 매우 가능성이 높은 새로운 배지가 될 수 있을 것으로 보였다. 현재, 사용되고 있는 톱밥의 가격 (20 kg 고무나무톱밥=6500 Riel 혹은 1.6 USD)과 비교했을 때, 아카시아톱밥의 가격(20 kg=1000Riel 혹은 0.25USD)이 매우 낮아 버섯의 생산에 투자되는 비용을 크게 줄여 경제성을 높일 수 있을 것으로 사료된다.
