Abstract: Methods for determining thermophilic enzymatic activity include heating a substrate solution in a plurality of closed volumes to a predetermined reaction temperature. Without opening the closed volumes, at least one enzyme is added, substantially simultaneously, to the closed volumes. At the predetermined reaction temperature, the closed volumes are agitated and then the activity of the at least one enzyme is determined. The methods are conducive for characterizing enzymes of high-temperature reactions, with insoluble substrates, with substrates and enzymes that do not readily intermix, and with low volumes of substrate and enzyme. Systems for characterizing the enzymes are also disclosed.

Abstract: Provided herein are methods for producing a fermentation product, such as ethanol, by co-culture of a member of the genus Paenibacillus and an ethanologenic microbe, such as yeast or E. coli. Also provided are methods for making enzymes useful in the saccharification of a pretreated lignocellulosic material. The enzymes may be made by culturing a member of the genus Paenibacillus in a composition suitable for production of such enzymes. An example of such a composition is a pretreated lignocellulosic material, for example, spent hydrolysates. Also provided are genetically modified members of the genus Paenibacillus that have been genetically modified to not produce an antimicrobial, for instance, a polymyxin E.
