【 摘 要 】

According to UN, earth population will increase approximately 7.3 billion people up to 11.2 billion from 2015 until 2100. On the other side, food needs are not balance with the availability of food on earth. People of the world need solution for a new food source. By cellulose digesting ability, people analyzed can consume cellulose as the new food source to get glucose. The aims of research is obtaining termite gut cellulase bacteria selected which is potential as probiotic to split cellulose. Method used was as follows; isolation of termite gut microbes, microbial cellulase purification by screening method and probiotic test includes microbial pathogenicity test and human stomach acid and salt osmotic concentration resistance test. The result shows, 3 pure isolates of termite gut microbes can break down cellulose in the medium 1% CMC and 0.1% congo red (indicator of cellulose degradation activity) and life at pH 2- 2.5 and osmotic salt condition. Two isolates show the activity of gamma hemolysis (non-pathogenic in terms of pathogenicity on human blood). In conclusion, there are isolated termite gut microbes can be used as probiotic candidate for human to digest cellulose of the new food source for global food scarcity era.
