污泥水解蛋白液对食用菌生长的影响研究

将污泥(食品工厂污泥)经过酸碱水解制备水解蛋白液(肽类和氨基酸复合物,属于微生物蛋白)、并与豆粕(植物蛋白)、屠宰厂动物羽毛(动物蛋白)水解蛋白液、以及常规食用菌氮源麸皮、大米制糖厂米渣作为平菇栽培氮源或营养添加剂,测试对平菇的菌丝生长、产量和生物转化率的影响。结果表明,几种水解蛋白液对平菇的菌丝生长、产量、生物转化率影响明显,污泥水解蛋白液对菌丝的生长效果最好,其余2种水解蛋白液也有促进作用。添加污泥水解蛋白液最高产量可达806 g/袋,添加豆粕水解蛋白液的最高产量为532 g/袋,添加屠宰厂动物羽毛水解蛋白液的产最高量为525 g/袋;对照为480 g/袋(常规棉籽壳)。生物转化率分别为161.2%、106.4%和105.0%,而对照生物转化率为96%;增产率分别为67.92%、10.83%和9.38%。因此,污泥、豆粕、屠宰厂动物羽毛蛋白水解液可提高平菇产量,该研究也为污泥资源化利用建立了基础。

First Estimations of Plant Acridone Alkaloid Implemented in Mushroom Mycelium Growth

Acridone derivatives are widespread in nature and known to be capable of having a variety of biological activities, but there is not any information on the acridone series compounds in relation to higher fungi, including edible mushrooms available in literature at all. Research into the character of the mode of action of these substances on various living systems is necessary to elucidate the possible unfavorable biological consequences and improve measures on their ecological safety. In this work, the effect of acridone-N-acetic acid on mushroom mycelial growth was tested and the culture of basidiomycete Lentinula edocles （shiitake） has been used. The influence of acridone additive upon the fungal mycelium growth on liquid （submerged） and agar media was examined within the wide concentration range of acridone carboxy-derivative. The results obtained testify to the relative ecological safety of these substances for mushroom organism, and to the mycelial growth promoting capability of acridone-N-acetic acid at favorable concentrations, both under the solid-phase and liquid-phase culture conditions. In fact, the very first step toward the investigation into the systems ＂macromycete-acridone series compound＂ has been made.
