In this study, isolate 23 microbes with lipase activity from Wu-Jie scrap heap at Ilan and Taichung Environmental Protection Section. When the microbes incubator in 50oC, there are isolates B61 and M63 that lipase activity are better than others. Brevibacillus borstelensis SH168 isolated from NTU resterant food waste compost is used as control check. Isolates B61, M63 and Brevibacillus borstelensis SH168 determine the lipase activity by the LB with tributyrin. The lipase activity of isolates B61 and M63 are 2~3 fold higher than Brevibacillus borstelensis SH168. So isolates B61 and M63 are more useful in producing lipase. Isolate B61 can grow at pH 5~9, and at temperature 20oC ~ 60oC; isolate M63 can grow at pH 6~10, and at temperature 30oC ~ 50oC. Isolates B61 and M63 were identified by 16S rRNA. Isolate B61 is Bacillus circulans, and isolate M63 is Bacillus species.

Fat tissue is hydrolyzed and released fatty acid as well triolein by lipase; on the other hand, high fat diet can't be directly absorbed across the intestinal mucosa.it must be firstly decomposed into one 2-monoglyceride and two free fatty acids by pancreatic lipase ,which is delivered into the lumen of the gut as a constituent of pancreatic juice.

脂肪酶能够使体内的多余脂肪组织分解成三酸甘油酯，另一方面，人体摄入高脂肪食物，并不能直接被小肠粘膜吸收，而是先被小肠内的胰脂肪酶分解成2-单酸甘油酯和两个游离脂肪酸，然后和胰液一起被运输到肠道的内腔被吸收。
