项目摘要

Recent diversification and luxurization of food resources and the rapid expansion of economic activity allowed us unexpected in crease in food waste which has caused over-consumption of the world resources in Japan, in addition to the resulted polution claim. These problems should be solved by the microbial treatment of waste for the effective utilization of waste such as feed or fertilizer. In this study, microbial conversion of food waste to chicken feed was examined. The soy pulp or soy bean-curd (tofu) waste, so called "OKARA" in Japanese was used as a simplified food waste. Rhizopus oligosporus, a fungous strain for fermenting "Tempe" in South East Asia was used for microbial treatment of OKARA.Fresh OKARA is known as a good medium for microorganisms due to the increse in the unexpected microbial cells up to 10^8. The pH value of OKARA was adjusted with organic scids to around 5 to control these undesirable cells and to enhance growth of R.oligosporus. This organism released CMCasc, xylanse, amylase and other enzymes into OKARA in addition to some antibacterial materials against Bacillus subtilis This fermented OKARA was dried up with hot air in the "Biorecytor". The dried powder was mixfd with commercialized cheken feed at the concentration of 10 and 20%. The mixed feed was fed to male chiks of 9 week-old for 3 weeks. The feeting of fermented OKARA resulted the body weight-gain slightly faster than feeding non-fermented OKARA,indicating that partial or preliminary digestion of OKARA by some enzymesfrom the microorganism may enhanced intake of nutrients in OKARA.

近年来，食品资源的多样化和奢侈化以及经济活动的迅速扩张，导致食品浪费出人意料地增加，除了由此造成的污染索赔之外，还导致日本过度消耗世界资源。这些问题应该通过废物的微生物处理来解决，以有效利用饲料或肥料等废物。在这项研究中，研究了食物垃圾向鸡饲料的微生物转化。大豆浆或豆腐（豆腐）废物，在日语中称为“OKARA”，被用作简化的食物废物。 OKARA的微生物处理采用了东南亚发酵“Tempe”的真菌菌株Rhizopusolisporus。新鲜的OKARA因其意想不到的微生物细胞数增加高达10^8而被称为微生物的良好培养基。用有机 scids 将 OKARA 的 pH 值调节至 5 左右，以控制这些不良细胞并促进少孢红霉的生长。该生物体除了一些针对枯草芽孢杆菌的抗菌物质之外，还向OKARA中释放CMCasc、木聚糖酶、淀粉酶和其他酶。将发酵后的OKARA在“Biorecytor”中用热空气干燥。将干燥的粉末与商业化的车肯饲料以10%和20%的浓度混合。将混合饲料喂给9周龄的雄性雏鸡，连续喂养3周。发酵OKARA的生长导致体重增长略快于饲喂非发酵OKARA，表明微生物中的某些酶对OKARA的部分或初步消化可能会增加OKARA营养物质的摄入。
