Civet coffee is fermented coffee which is produced naturally in the digestive tract of mongoose. The production of civet coffee is relied on the availability of the civet, therefore the production is costly. This research aim was to produce synthetic civet coffee by enzymatic fermentation.The enzymes were produced by cellulolytic, xylanolytic, and proteolytic bacteria that were isolated from civet feces. The combination treatment was examined the highest enzymatic production from different bacteriawiththe variation oftemperature during four days. During the fermentation, the produced enzymes were used for hidrolize the substrate. Enzymatic process was determined by changing the total and reducing of sugar, weight losses, protein content and the enzyme activity produced in the substrate. The fermentation was done by cellulolytic bacteria and combination of threebacteria. Alltreatment were resulledan approximate similarcaffein reduction (48%), however the nutrition content indicated by organic acid were shown that thecoffee fermentation has a low oxalic acid and higher butyric, lactic and ascorbic acid.
