Abstract: The present invention provides modified promoters from Candida troplicalis CYP and POX4 genes. The modified promoters have various sequence motifs added, deleted, or altered in order to modulate expression of a coding sequence operably linked thereto. The sequence motifs comprise repressors of gene induction (URS sequences) and activators of gene induction (UAS sequences) as well as oleic acid response elements (ORE sequences). Yeast host cells comprising such modified promoters are also provided. Methods of altering expression of a protein of the beta or omega oxidation pathways using a subject modified promoter are also provided.

Abstract: A bioprocess for producing carboxylic acids, alcohols and aldehydes is provided by culturing Candida sp. in a fermentation medium containing various defined substrates.

Abstract: The invention is a radiation curable coating containing an antimicrobial agent, where upon irradiation with UV light, the radiation curable coating rapidly cures to a polymeric coating. The polymeric coating has durable antimicrobial properties, being especially effective at preventing the growth of Staphylococcus aureaus and Kleibsella pneunoniae on wood flooring and furniture. The major components in the radiation curable coating are a urethane acrylic oligomer, a radiation cure package, an antimicrobial agent, a cross-linking agent, and optionally, an additive package. The radiation curable urethane oligomer is a relatively short chain backbone urethane polymer that is end capped with a radiation curable moiety, where the moiety is an acrylic. The cross-linking agent is one or more monomers used to lower the viscosity and promote cross-linking, and include acrylate esters of mono-, di-, tri-, or tetrafunctional alcohols. The radiation cure package contains at least one photoinitiator.
