摘要:
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.
摘要:
A substantially pure Candida host cell for the production of a α-carboxyl-ω-hydroxy fatty acid having a carbon chain length in the range from C6 to C22, a α,ω-dicarboxylic fatty acid having a carbon chain length in the range from C6 to C22, or mixtures thereof, is provided. The Candida host cell is characterized by a first genetic modification class and a second genetic modification class. The first genetic modification class comprises one or more genetic modifications that disrupt the peroxisomal β-oxidation pathway. The second genetic modification class comprises one or more genetic modifications that collectively or individually disrupt at least one gene selected from the group consisting of a CYP52A type cytochrome P450, a fatty alcohol oxidase, and an alcohol dehydrogenase.
摘要:
A dihydroxyphenyl cross-linked macromolecular network is provided that is useful in artificial tissue and tissue engineering applications, particularly to provide a synthetic macromolecular network for a wide variety of tissue types. In particular, artificial or synthetic cartilage, vocal cord material, vitreous material, soft tissue material and mitral valve material are described. In an embodiment, the network is composed of tyramine-substituted and cross-linked hyaluronan molecules, wherein cross-linking is achieved via peroxidase-mediated dityramine-linkages that can be performed in vivo. The dityramine bonds provide a stable, coherent hyaluronan-based hydrogel with desired physical properties.
摘要:
A method for inactivating spermatozoa, neutralizing or inactivating a virus, and neutralizing or inactivating HIV using sophorolipids having spermicidal and/or antiviral properties produced by synthesizing the sophorolipid by fermentation of Candida bombicola in a fermentation media to form a natural mixture of lactonic sophorolipids compounds and non-lactonic sophorolipids compounds and utilizing the natural mixture as a spermicidal and/or antiviral agent, and/or separating the lactonic sophorolipids from the natural mixture to form a lactonic fraction and mixing all remaining fractions to form a non-lactonic fraction and utilizing the lactonic fraction and/or the non-lactonic fraction as an spermicidal and/or antiviral agent, and sophorolipid compounds for use as spermicidal and/or antiviral agents.

摘要:
A synthetic nucleus pulposus is provided that is useful in treatment of degenerative disc disease, augmentation of a degenerate disc, and alleviation of back pain. In an embodiment the synthetic nucleus pulposus comprises hyaluronan macromolecules that have been cross-linked via dihydroxyphenyl linkages. The synthetic nucleus pulposus restores or improves the water-retention capability of the disc. A method of treating an intervertebral disc with the cross-linked hyaluronan macromolecules is also provided. A method of regenerative therapy to address loss of cells of nucleus pulposus of an intervertebral disc based on treatment with the cross-linked hyaluronan macromolecules and mesenchymal stem cells is also provided.
