【中文摘要】 食品工業中用迷迭香提取抗氧化物質后的殘渣(rosemary processing waste RPW)拌入粉碎的玉米粒可以用作栽培糙皮側耳的培養料。提取抗氧化劑后的迷迭香殘渣RPW-1中所含提取殘留的丙酮對栽培有害,RPW-1直接栽培糙皮側耳所獲子實體產量比用RPW-2(廢料充分通氣,去除殘存的丙酮)平均低49%。試驗中獲得最高生物效率(67%)的培養料配比為RPW-2中加入30%(w/w)粉碎的玉米粒(crushed corn seeds CCS)和2%CaCO3。增加培養料中的麩皮(wheat bran WB)比例(降低C/N比)可加快菌絲生長速度,但通常導致子實體產量降低。試驗中菌絲生長最快(23 d生長9.9 cm)的培養料配比為RPW-2中添加30%(w/w)CCS和30%(w/w)WB,C/N比為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. 還原
