Effective microorganism as new cellulose regrading bacteria to produce biofuels / Muhammad Zakri Iezaac Mohd Zaidin ...[et al.]

Nowadays, biofuel such as bioethanol and biomethanol has been widely used by many countries. Example application of biofuels is used as fuel for transportation. Study found that this biofuel can be produced by using cellulose in living things. Then it was related from a study which is production of bioethanol from newspaper using Cythophagahutchnosonni bacteria as biodegradable bacteria for hydolysis process and fermentation process using common yeast, Sacacharomyces cerevisae. Newspaper which is one of municipal waste which contain cellulose has been used as a substrate in producing bioethanol. Fermentation process of newspaper has been proved by a study to produce bioethanol. The purpose of this experiment is to produce biomethanol using Effective Microorganisms (EM) as biodegradable bacteria. It undergo several processes which are pre-treatment of substrate using hydrochloric acid, hydrolysis of substrate using EM and addition of yeast S. cerevisae for fermentation process. Biofuels produced was analysed using Refractive Index method. As a result, 91 % - 93% concentration of biomethanol were produced. Based on analysis, it contains average of 33% biomethanol, 4% of water in each sample taken.
