Compositions comprising cellulase and at least one poly alpha-1,3-glucan ether compound having a degree of substitution with an organic group of about 0.05-3.0 are disclosed. Such compositions can be dry or aqueous, the latter of which can have a viscosity of at least about 10 cPs. The disclosed composition can be in the form of a personal care product, household product, or industrial product, for example. Also disclosed are a method for preparing an aqueous composition comprising cellulase and a poly alpha-1,3-glucan ether compound, and a method of treating a material such as fabric by contacting it with this aqueous composition.

Compositions containing one or more poly alpha-1,3-glucan ether compounds

Compositions comprising cellulase and at least one poly alpha-1,3-glucan ether compound having a degree of substitution with a positively charged organic group of about 0.05-3.0 are disclosed. Such compositions can be dry or aqueous, the latter of which can have a viscosity of at least about 10 cPs. The disclosed composition can be in the form of a personal care product, household product, or industrial product, for example. Also disclosed are a method for preparing an aqueous composition comprising cellulase and a poly alpha-1,3-glucan ether compound, and a method of treating a material such as fabric by contacting it with this aqueous composition.

A process for producing poly alpha-1,3-glucan with reduced molecular weight is disclosed. The process comprises contacting water, sucrose, a polar organic solvent, and a glucosyltransferase enzyme in a solution to produce poly alpha-1,3-glucan. This contacting step results in the production of poly alpha-1,3-glucan having a reduced molecular weight compared to the molecular weight of a poly alpha-1,3-glucan made in the absence of the polar organic solvent.

A process for production of poly (&#x3b1; 1,3 glucan) from a renewable feedstock, for applications in fibers, films, and pulps. The effect of addition of tetraborate in increasing the yield of the desired end products, poly (&#x3b1; 1,3 glucan) and fructose, and decreasing formation of the undesired by-product leucrose.

Xylose-utilizingstrains studied were found to accumulate ribulose when grown in xylose-containing media. Engineering these strains to increase ribose-5-phosphate isomerase activity led to reduced ribulose accumulation, improved growth, improved xylose utilization, and increased ethanol production.

Xylose utilization in recombinant zymomonas

Xylose-utilizing, ethanol producing strains ofwith improved performance in medium comprising biomass hydrolysate were isolated using an adaptation process. Independently isolated strains were found to have independent mutations in the same coding region. Mutation in this coding may be engineered to confer the improved phenotype.
