Abstract: A substantially pure Candida host cell is provided for the biotransformation of a substrate to a product wherein the host cell is characterized by a first genetic modification class that comprises one or more genetic modifications that collectively or individually disrupt at least one alcohol dehydrogenase gene in the substantially pure Candida host cell.

Abstract: A method for producing sophorolipids having protein inducer and/or repressor activities having the steps of synthesizing the sophorolipid by fermentation of Candida bombicola in a fermentation media to form a natural mixture of lactonic sophorolipids and non-lactonic sophorolipids and then utilizing the natural mixture as a protein inducing agent, utilizing the natural mixture as a protein repressing agent, and/or utilizing the natural mixture as a combined protein induction/repressor agent. An application of the sophorolipid compound produced according to the method as a microbial media component.

Abstract: An ?-carboxyl-?-hydroxyl fatty acid oxidized from a substantially pure Candida host cell, wherein the substantially pure Candida host cell is characterized by a first genetic modification class that comprises one or more genetic modifications that collectively or individually disrupt an alcohol dehydrogenase gene, and a second genetic modification class, wherein the second genetic modification class comprises an insertion of a first gene into the Candida host cell genome.

Abstract: The present invention relates to aliphatic or aliphatic-aromatic polyesters and copolyesters comprised of biobased ?-hydroxyfatty acids or derivatives thereof, processes for the preparation thereof, and compositions thereof having improved properties. The copolyesters of the present invention may also contain additional components that can be selected from aliphatic or aromatic diacids, diols and hydroxyacids obtained from synthetic and natural sources. The biobased ?-hydroxyfatty acids that comprise the polyesters and copolyesters of the present invention are made using a fermentation process from pure fatty acids, fatty acid mixtures, pure fatty acid ester, mixtures of fatty acid esters, and triglycerides from various sources. The polyesters of the present invention may contain various amounts and types of ?-carboxyfatty acids depending on the engineered yeast strain used for the bioconversion as well as the feedstock(s) used.

Abstract: The present invention relates to polyurethane polymers comprising as part of its polymer backbone biobased ?-hydroxyfatty acids or derivatives thereof, processes for the preparation thereof, and compositions thereof having improved properties. The polyurethanes of the present invention are prepared from copolyester prepolymers comprising the biobased ?-hydroxyfatty acids that may also contain additional components that can be selected from aliphatic or aromatic diacids, diols and hydroxyacids obtained from synthetic and natural sources. The biobased ?-hydroxyfatty acids that comprise the polyurethanes and copolyester prepolymers of the present invention are made using a fermentation process from pure fatty acids, fatty acid mixtures, pure fatty acid ester, mixtures of fatty acid esters, and triglycerides from various sources.
