山西是酿醋之乡,食醋生产量很大,据初步统计全省年产醋糟数十万吨至成百万吨,目前却没有很好的利用途径。除极少数用作反刍家畜的辅助性饲料外,几乎全部以废物处理,既造成了资源的浪费,又污染了环境。为了变废为宝,合理利用废弃资源,改善生态环境,我们于1989年进行了醋糟栽培凤尾菇的试验,取得了比较令人满意的效果。一、材料与方法 1.菌种培养凤尾菇菌种为p_L-27,由山西农业大学微生物教研室提供。母种、原种,按常规程序制作,栽培种栽培料配方为:干醋糟80％,棉籽壳15％,碳酸钙3％,石膏粉2％。将料按配方比例混匀后,加水使含水量为65％,装瓶,高压灭菌(1.5kg/
Shanxi is a village of vinegar, vinegar production is very large, according to preliminary statistics, the province’s annual output of vinegar hundreds of thousands of tons to millions of tons, there is no good way to use. Except for a very small number of auxiliary feedstuffs used for ruminants, almost all of them are disposed of as waste, causing waste of resources and contaminating the environment. In order to turn waste into treasure, rational use of waste resources, improve the ecological environment, we conducted in 1989 vinegar dregs cultivated mushrooms trial, and achieved satisfactory results. First, the material and methods 1. Fungus cultivation Pleurotus mushroom p_L-27, provided by the Department of Microbiology, Shanxi Agricultural University. Mother species, the original species, according to conventional procedures, cultivation of cultivated materials recipe: 80% dry vinegar, cottonseed shell 15%, calcium carbonate 3%, gypsum powder 2%. The material will be mixed according to the proportion of the formula, add water to a water content of 65%, bottling, autoclaving (1.5kg /
