Bioethanol is continuously being developed in order to cope with the depleti on of petroleum worldwide nowadays. However, bioethanol production faces problems like tbe acc umulation of ethanol in the fermenta tion broth. In this research, the production of bioethanol was perfotn1ed using Escherichia coli (KGII), while simultaneously using castor oil that functions as a selective separa tor to absorb and separate the ethanol from the fermentation broth. Castor (Ric inus cummun is) tree, a family member of Euphorbiacae is a resourccil'! plant that prod uces castor oi l. The experiment was conducted to identify and determine whether castor oil have any effec t on E. coli growth and fermenting activities. The analysis of this experiment includes plate count ana lysis of E. coli and High Performance Liquid Chromatography (HPLC). In this study, E. coli KO 1J is used as fermenting organisms towards glucose. The best glucose concentration J.J1 producing hi gh ethanol yield was 5% glucose. The effects of the castor oil during anaerobic fermentation include the effect on E. coli KO 11 growth and other by-producls.
