Ethanol production using Zymomonas mobilis immobilized on an ion exchange resin

Effect of commercial feedstocks on growth and morphology of Zymomonas mobilis

“…In addition to the identification of potential growth and fermentation inhibitors, the effect of crude substrates on critical growth morphologies (eg. flocculating and immobilized -cell systems; Fein et al, 1983a;Margaritis et al, 1981;Krug and Daugulis, 1983) should be considered.…”

“…The occurence of filamentous growth has recently been reported in an immobilized cell column, resulting in plugging of the reactor and system shutdown (Krug and Daugulis, 1983).…”

Development of corn silk as a biocarrier for <i>Zymomonas mobilis</i> biofilms in ethanol production from rice straw

“…This work also documented increases in the immobilized cell concentrations for Z. mobilis biofilms on delignified corn silk and increased ethanol productivity in fermentations. Many different abiotic substrates have been used as immobilizers for Z. mobilis in the production of bioethanol, including glass beads, anionic exchangers and polypropylene composite agricultural waste (Krug and Daugulis, 1983;Kunduru and Pometto Iii, 1996;Todhanakasem et al, 2015;Weuster-Botz et al, 1993). The present study is unique in that it is the first work to show the biofilm structure and biofilm forming ability of Z. mobilis on agricultural material, as well as illustrating the potential for enhanced ethanol production from lignocellulosic hydrolysate.…”

Continuous ethanol fermentation ofZymomonas mobilis using soy flour as a protective agent

“…Fermentation-ethanol has been and is still widely studied as an alternative fuel and chemical feed-stock, and its industrial production has been increasing, Many papers on ethanol fermentation by Zymomonas mobilis have been published in the last few years (Rogers et al, 1979;Lee et al, 1981;Grote et al, 1980;Margaritis et al, 1981;Prince et al, 1982;Fein et ai., 1983;Krug et al, 1983;Charley et al, 1983). In general, the published data indicate that several strains of Z. mobilis have higher specific ethanol productivity when compared to that of yeasts which are used in traditional ethanol fermentations.…”
