For the purpose of efficiency of the cellulosic bioethanol production we studied immobilized microbes. We used Silica gels as carrier and examined novel methods to contain microbes in them. In consideration of the adverse effects to a microbe, gel-reactions did at low temperature and in the near neutral pH domain. By the choice of the additive such as the PVA, good gels were provided. For ethanol fermentation 5 strains, Saccharomyces cerevisiae K701N Pichia stipis NBRC1687, Candida shehate NBRC1983, Pachysolen trannophilus NBRC1007 and Zymomonas mobilis NBRC13757 were used. By using new immobilized methods, Saccharomyces cerevisiae K701 and Pachysolen trannophilus NBRC1007 held high ethanol productive capacities after immobilization.
