Abstract: Presented herein are oleaginous strains of yeast such as Saccharomyces cerevisiae that have been modified to allow for xylose utilization. Such strains are also modified to allow for higher lipid accumulation utilizing a broad range of sugar monomers such as those released during pretreatment and enzymatic saccharification of lignocellulosic biomass. Methods of producing lipids and ethanol using these yeast strains are also disclosed.

Abstract: Presented herein are methods of using cell wall degrading enzymes for recovery of internal lipid bodies from biomass sources such as algae. Also provided are algal cells that express at least one exogenous gene encoding a cell wall degrading enzyme and methods for recovering lipids from the cells.

Abstract: Provided herein is an isolated Cel7A polypeptide comprising mutations in the catalytic domain of the polypeptide relative to the catalytic domain of a wild type Cel7A polypeptide, wherein the mutations reduce N-linked glycosylation of the isolated polypeptide relative to the wild type polypeptide. Also provided herein is an isolated Cel7A polypeptide comprising increased O-linked glycosylation of the linker domain relative to a linker domain of a wild type Cel7A polypeptide. The increased O-linked glycosylation is a result of the addition of and/or substitution of one or more serine and/or threonine residues to the linker domain relative to the linker domain of the wild type polypeptide. In some embodiments, the isolated Cel7A polypeptide comprising mutations in the catalytic domain of the polypeptide relative to the catalytic domain of a wild type Cel7A polypeptide further comprises increased O-linked glycosylation of the linker domain relative to a linker domain of a wild type Cel7A polypeptide.

Abstract: A novel strain of Lactococcus lactis subspecies cremori (“Ropy 352”) has been identified and isolated. Ropy 352 produces a previously unknown exopolysaccharide (EPS 352) that when expressed or added to milk, imparts highly desirable sensory characteristics to the milk, including making the milk very thick, with a very smooth mouth-feel, and slightly sweet with an obvious “chewable-bite”.
