酱渣、醋糠、醋糟、发泡糟是酿造系统生产的下脚料,它的数量很大,仅上海醋厂和酿造六厂每天就有30多吨。这些渣糟,目前有的是作粗饲料喂饲动物,饲料效率很差,有的已成为企业亟待解决的问题。我们通过废渣糟的成分测试,看到这些渣糟含有粗蛋白、粗纤维、粗脂肪以及矿物质等,若能经过适当处理及合理调配,定能得到充分利用。因此,我们根据食用菌的营养要求,在分析常规培养料的营养成分的基础上,进行酿造废渣糟栽培毛木耳试验,取得了较好的效果。一、材料和方法(一)供试材料菌种为AP_4毛木耳菌株,引自上海农科院食用菌研究所。正式试验前,曾将此菌种试种于以废渣糟代料的各种培养基上,在初试成功基础上,筛选出四个配方作进一步扩大试验。以常规料配方为对照,共设五个试验小区,各小区配料是:试1(对照)为棉子壳、木屑、糠;试2为废渣糟、木屑、米糠;试3为棉子壳、废渣糟、米糠;试4为棉子壳、木屑、废渣糟;试5为废渣糟。 Sauce residue, vinegar bran, vinegar dregs, bad foam brewing system is the production of waste, it is a large number, only six vinegar factory in Shanghai and brewing more than 30 tons per day. At present, some of these slag grains are used as roughage-fed animals, and the feed efficiency is very poor. Some have become urgent problems to be solved by enterprises. We have passed the waste residue testing and found that these residues contain crude protein, crude fiber, crude fat and minerals which, if properly treated and properly formulated, will be fully utilized. Therefore, based on the nutritional requirements of edible fungi, we analyzed the nutritional content of conventional culture materials and carried out the brewing waste malt fungus cultivation experiment, and achieved good results. First, the material and methods (a) for the test material species AP_4 hairy fungus strains, cited from the Shanghai Academy of Agricultural Sciences Institute of Edible Fungi. Prior to the official test, this strain was planted on various media using waste residue as substitute material. Based on the successful initial test, four formulations were screened for further expansion. Take the conventional material formula as a control, a total of five experimental plot, the district ingredients are: Test 1 (control) for the cotton seed shell, sawdust, chaff; test 2 for the bad waste, sawdust, rice bran; Waste residue, rice bran; test 4 as the cotton seed shell, sawdust, waste residue; test 5 for the waste residue.
