【中文摘要】 食品工业中用迷迭香提取抗氧化物质后的残渣(rosemary processing waste RPW)拌入粉碎的玉米粒可以用作栽培糙皮侧耳的培养料。提取抗氧化剂后的迷迭香残渣RPW-1中所含提取残留的丙酮对栽培有害,RPW-1直接栽培糙皮侧耳所获子实体产量比用RPW-2(废料充分通气,去除残存的丙酮)平均低49%。试验中获得最高生物效率(67%)的培养料配比为RPW-2中加入30%(w/w)粉碎的玉米粒(crushed corn seeds CCS)和2%CaCO3。增加培养料中的麸皮(wheat bran WB)比例(降低C/N比)可加快菌丝生长速度,但通常导致子实体产量降低。试验中菌丝生长最快(23 d生长9.9 cm)的培养料配比为RPW-2中添加30%(w/w)CCS和30%(w/w)WB,C/N比为24。
【英文摘要】 Rosemary processing waste(RPW) generated after extraction of antioxidant components for the food industry,in combination with crushed corn seeds,represented a suitable growth substrate for the cultivation of Pleurotus ostreatus.On average,fruit body yields were 49% lower on substrate mixtures containing RPW-1,containing residual acetone from the antioxidant extraction process,compared to substrates incorporating RPW-2 which had been allowed to stand in well-aerated conditions in order to remove residual solvent.The highest Biological Efficiency value(67%) were recorded with a substrate mixture containing 30%(w/w) crushed corn seeds(CCS) mixed with RPW-2 and 2% CaCO3.Increasing proportions of wheat bran(WB) in the mixtures decreased the C/N ratio,had a positive effect on mycelial growth rates,but generally resulted in lower fruit body yields.The highest vegetative growth rate(9.9 cm in 23 days) was recorded on substrate mixtures with a C/N ratio of 24 and containing RPW-2 supplemented w...更多ith 30%(w/w) CCS and 30%(w/w) WB. 还原
