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。
Rosemary processing waste RPW extracted from rosemary in the food industry Mixing ground corn kernels can be used as a culture medium for cultivating Pleurotus ostreatus. Extracts of residual acetone from rosemary residue RPW-1 after extraction with antioxidants were harmful to the cultivation. The yield of fruiting bodies obtained from RPW-1 directly cultivated Pleurotus ostreatus was significantly lower than that of RPW-2 (full ventilation of waste material and removal of residual acetone ) On average 49% lower. The highest bioavailability (67%) of the culture material in the trial was 30% (w / w) crushed corn seeds CCS and 2% CaCO3 added to RPW-2. Increasing the wheat bran WB ratio (decreasing the C / N ratio) in the culture increases the rate of mycelial growth, but usually results in a decrease in fruiting bodies. The culture medium with the fastest mycelial growth (9 days at 23 days) was supplemented with 30% (w / w) CCS and 30% (w / w) WB for RPW-2 with a C / N ratio of 24.
