    Abstract

    Mustofa A, Suranto. 2009. Activity of Zymomonas mobilis on ethanol production made of cashew nut apple (Anacardium occidentale) with different sources of nitrogen. Nusantara Bioscience 1: 105-109. This research is aimed at identifying Zymomonas mobilis in producing ethanol through batch fermentation process (in 24, 48 and 72 hours) using cashewnut apple extract (red, green and yellow variety) and urea, ammonium sulphate, extract of green peanut sprout and extract koro (Mucuna pruriens) as sources of nitrogen. The research showed that green cashewnut extract with ammonium sulphate in 24 hours of fermentation produced ethanol in optimum result. This treatment had pH of 5.87, 7.64 g/100 mL of sugar (with 48.44% of consumption), 8.0x10 7 amount of bacterium (µ = 0.154) and production of ethanol equal to 33.02 g/L (Ye = 90.19%). Key words: Zymomonas mobilis, cashewnut apple extract, ethanol.
