摘要： This invention relates to a method for utilizing less purified starch in fermentation processes. One example is a recombinant E. coli containing a exogenous extracellular isoamylase activity that is capable of utilizing small oligomers containing (1,6) linkages (including but not limited to isomaltose and panose) in fermentations to produce useful products. The invention is useful in large-scale industrial biofermentations by reducing the cost of the substrate carbohydrate.

摘要： Strains of xylose utilizing Zymomonas with improved xylose utilization and ethanol production during fermentation in stress conditions were obtained using an adaptation method. The adaptation involved continuously growing xylose utilizing Zymomonas in media containing high sugars, acetic acid, ammonia, and ethanol.

摘要： Xylose-utilizing Z. mobilis strains were found to have improved ethanol production when grown in medium containing mixed sugars including xylose if sorbitol or mannitol was included in the medium. The effect was seen in concentrations of mixed sugars where no growth lag period occurs, as well as in higher sugars concentrations.
摘要翻译： 当发现含木糖的运动发酵单胞菌菌株在含有木糖的混合糖的培养基中生长时，如果在培养基中包含山梨糖醇或甘露醇，则发现其具有改善的乙醇生产。 在没有生长滞后期的混合糖的浓度以及较高的糖浓度下观察到效果。
