“…The monitoring of glucose concentration in the fermentation broth during anaerobic fermentation is important as glucose concentration affects the rate of ethanol production (Periyasamy 2009). Furthermore, based on a previous study conducted by Altintas et al (2002), glucose concentration is proportional to the ethanol production.…”

“…Srivastava et al (1997) showed that the optimum, initial pH of guava pulp medium was 5 and achieved maximum yield of 5.8 % of ethanol at that pH. Periyasamy et al (2009) obtained the maximum bioethanol at pH 4 from sugar molasses using S. cerevisiae. Ado et al (2009) studied bioconversion of cassava starch into ethanol and found maximum yield of ethanol at pH 5.…”

“…They found maximum production of ethanol at 32°C and 14 h of incubation. Periyasamy et al (2009) observed bioethanol production from sugar molasses using S. cerevisiae and reported the maximum bioethanol yield of 53 % at temperature 35°C. Ado et al (2009) explained ethanol production from cassava starch using co-culture of Aspergillus niger and S. cerevisiae in a simultaneous saccharification and achieved the maximum ethanol at 35°C.…”

The potential environmental benefits that can be obtained from replacing petroleum fuels with biofuels derived from renewable biomass sources are the main driving forces for promoting the production and use of biofuels. Due to depletion of fossil fuels, ethanol, which can be obtained via the bioconversion of renewable feedstock, is widely regarded as an efficient alternative for gasoline as transportation fuel. Biomass energy can play an important role in reducing greenhouse gas emissions. Rice bran is a by-product of milling process of rice, and due to its carbohydrate contents, it may serve as good source for bioethanol production. The present study deals with bioethanol production from rice bran and screening of bioethanol-producing bacteria from rice bran. In the screening process, three fermentative bacteria were obtained; they were studied on the basis of morphology, biochemical characteristics and maximum bioethanol production. The maximum bioethanol-producing bacteria was identified by sequencing method. The bacteria thus identified as Bacillus cereus strain McR-3 is a novel bacteria reported in bioethanol production from rice bran substrate. Different parameters like temperature and pH also affects the production of bioethanol. It was observed that optimum temperature and pH for maximum bioethanol production was 37°C and 5, respectively.

ABSTRAKBioetanol merupakan salah satu bahan bakar alternatif yang strategis untuk dikembangkan. Salah satu substrat yang menjanjikan untuk digunakan adalah molase. Molase merupakan hasil samping industri gula kristal tebu yang masih mengandung gula yaitu sekitar 45-54,6%.Bioetanol dari molase tebu berpotensi untuk dikembangkan karena sangat menguntungkan, pasokan cukup besar, tersedianya teknologi proses, serta tidak bersaing dengan pangan. Tulisan ini mengulas hasil-hasil penelitian dan implikasinya tentang bahan baku, proses, lingkungan yang berpengaruh serta strategi untuk meningkatkan produktivitas bioetanol dari molase tebu melalui rekayasa proses fermentasi. Pada pembuatan etanol, fermentasi merupakan proses yang memegang peranan penting. Pengaturan lingkungan fermentasi seperti suhu, pH, dan tekanan berpengaruh terhadap bioproses dalam fermentasi. Begitu pula penambahan bahan suplemen seperti gula, garam, dan ion logam menurut jenis dan konsentrasi yang tepat juga dapat mengoptimalkan proses fermentasi. Selain pengelolaan lingkungan dan penambahan bahan suplemen, strategi untuk peningkatan produktivitas bioetanol dari molase dapat dilakukan dengan: 1) penggunaan mikrobia selain Saccharomyces cerevisiae; 2) pretreatment; dan 3) metode fermentasi kontinyu. Penggunaan mikrobia selain Saccharomyces cerevisiae, seperti Zymomonas mobilis dapat meningkatkan produktivitas etanol hingga 55,8 g/L atau 27,9% dari total gula reduksi.Perlakuan pretreatment dapat meningkatkan produktivitas mikrobia dalam mengkonversi gula menjadi etanol, sedangkan penggunaan metode fermentasi secara kontinyu dapat meningkatkan produktivitas sebesar + 4.75 g/L/jam. Kata kunci : fermentasi, bioetanol, molase, bioproses ABSTRACT Bioethanol is one of strategic alternative fuel to develop. One of substrate that promises to be used is molasses. Molasses is by-product of sugar industry which contain of sugar about 45-54,6%. Bioethanol from sugarcane molase is necessary to develope because it is very profitable, large supply, availability technology, and no-competion to food. This paper was aimed to reviews some research results and their implications on raw materials, processes, advanced environments and strategies to increas bioethanol productivity of molasses through the fermentation process engineering. In the manufacture of ethanol, fermentation is an important holding process. In ethanol production, fermentation plays an important role. Fermentation environments arragement such as temperature, pH, and pressure can effect on bioprocess of fermentation. Similarly, the addition of supplemental ingredients such as sugar, salt, and metal ions by appropriate type and concentration can also optimize the fermentation process. In addition to environmental arrangement and supplemental adding, strategies to improve bioethanol productivity of molasses can be accomplished by 1) the use of microbes other than Saccharomyces cerevisiae; 2) pretreatment; and 3) continuous fermentation method. The use of microbes other than Saccharomyces cerevisiae, such ...
