COMPARATIVE STUDY FOR ETHANOL PRODUCTION FROM EMPTY FRUIT BUNCH PALM (EFBP) BY S. cerevisiae AND K. marxianus

Palm industry is a growing business in Colombia which generates a lot of waste that cause environmental problems around the palm crops. The largest proportion of residues corresponds to empty fruit bunch palm (EFBP) which is a good source of cellulose [1] available for second generation ethanol production. In previous researches optimum conditions for this biofuel were determined such as type of pretreatment, solid – liquid ratio, pre-hydrolysis time, enzymatic load and concentration of inoculum [2], under these conditions the effect of supplementation with Zn + on simultaneous saccharification and fermentation systems (SSF) was evaluated using about the fermentations in simultaneous saccharification and fermentation (SSF) using the yeast S. cerevisiae and K. marxianus in order to enhance the ethanol production using EFBP as substrate.
