Abstract

Composting is an alternative for recycling organic waste. Microorganisms that can degrade the components of organic waste are an essential part of composting. Isolation and selection of bacteria with the ability to degrade the elements of organic waste are the first steps to obtain an organic waste degrading agent. This study aimed to determine the characteristics and the enzymatic potential (cellulolytic, amylolytic, and proteolytic) of bacteria isolated from soil, cow dung and kitchen waste as candidates for organic waste degradation agents. The research begins with sampling and isolation of bacteria. The isolates obtained were tested qualitatively for their amylolytic, cellulolytic and proteolytic activities. Furthermore, bacterial isolates were characterized morphologically and biochemically. A total of 30 bacterial isolates were isolated from soil samples, cow dung and kitchen waste. The screening result showed that 6 isolates had amylolytic activity, 7 isolates had cellulolytic activity and 3 isolates had proteolytic activity. These bacterial isolates showed various morphological and biochemical characteristics. In general, soil samples, kitchen waste and cow dung contain potential bacteria as organic waste degrading agents

厨房垃圾和家畜粪便的特性和潜力成为有机废物生物降解制剂的候选人

堆肥是回收有机废物的另一种方法。能够降解有机废物成分的微生物是堆肥的重要组成部分。分离和选择具有降解有机废物元素能力的细菌是获得有机废物降解剂的第一步。本研究旨在确定从土壤、牛粪和厨余垃圾中分离的细菌作为有机废物降解剂的特性和酶解潜力(纤维素水解、淀粉水解和蛋白质水解)。这项研究从细菌的取样和分离开始。对分离得到的菌株进行了淀粉水解、纤维素水解和蛋白水解活性的定性测试。此外，对分离的细菌进行了形态和生化表征。从土壤样品、牛粪和厨余中共分离出30株细菌。筛选结果显示，6株具有淀粉水解活性，7株具有纤维素水解活性，3株具有蛋白水解活性。这些分离的细菌表现出不同的形态和生化特征。一般来说，土壤样品、厨余垃圾和牛粪含有潜在的细菌作为有机废物降解剂
