Abstract

Nypa fruticans are common widely distributed and useful palms in the mangrove forest of Southeast Asia. Nipa saps are source of sugars, minerals yeasts and nutrients which can be suitably used as raw for bioethanol fermentation. In addition, it is due to the really high percentage of sugars in nipa sap. Nipa sap sugar material consists of sucrose, glucose and fructose. Thus, no additional carbon sources were added in this study. The naturally existing microorganisms in nipa sap will act as the inoculum and the naturally existing sugar will act as the substrate for the production of bioethanol and others value added product such as lactic acid and acetic acid. Two different conditions were introduced to obtain the most economical way in producing value added product from nipa sap fermentation with the least amount of investment needed such as unsterilized bottle with unsterilized sap and also sterilized bottle with unsterilized sap. Although these two methods consumed almost similar level of energy for fermentation, sterilized condition was found to be more efficient. The profile of sugars and bioethanol was analysed by using High Performance Liquid Chromatography (HPLC). At the end of this experiment, the initial carbohydrate content in sterilized and unsterilized bottle were at 121.207 g/L respectively while the ethanol obtained was 13.181 g/L and lactid acid was 6.644 g/L and acetic acid was 0.855 g/L. The results showed that nipa sap actually can be used as alternative feedstock for bioethanol production and other values added product without any supplementation. Hence, those characteristics make nipa sap an interesting feedstock to be exploited for sustainable ethanol productions and other value added products.
