The present invention relates to a Candida tropicalis cell line, which comprises a mutant gene, having improved tolerance for cytotoxicity of stromal cells, and a method for producing dicarboxylic acid using the Candida tropicalis cell line. The Candida tropicalis cell line for producing dicarboxylic acid developed according to the present invention has improved tolerance for existing stromal toxicity as well as significantly improved efficiency for producing dicarboxylic acid compared to existing cell lines, thus can be used in biological production of dicarboxylic acid and is expected to have high industrial utility.

The technology relates in part to biological methods for modifying carbon flux in cells, engineered cells and organisms in which cellular carbon flux has been modified, and methods of using engineered cells and organisms for production of organic molecules.

Chimeric double peptide vaccines are disclosed, useful for inducing active immunity against Candida fungal infections. The chimeric peptide comprises an Fba peptide and an Met6 peptide, covalently linked to one another, with or without an intermediate linker. Fba and Met6 are cell surface components of Candida. When used as a vaccine, the chimeric double peptide vaccine induces stronger protective immunity against fungal infection than does the Fba peptide alone, or the Met6 peptide alone, or a mixture (not covalently linked) of the two peptides.

The invention includes a method of inhibiting Pho84 in a fungus comprising administering to the fungus an effective amount of a compound of formula 1.

A recombinant host capable of producing a steviol glycoside which overexpresses a polypeptide which mediates steviol glycoside transport and which polypeptide comprises the amino acid sequence set forth in SEQ ID NO: 29 or an amino acid sequence having at least about 50% sequence identity thereto. A recombinant host capable of producing a steviol glycoside which has been modified, preferably in its genome, to result in a deficiency in the production of a polypeptide which mediates steviol glycoside transport and which polypeptide comprises the amino acid sequence set forth in SEQ ID NO: 29 or an amino acid sequence having at least about 50% sequence identity thereto.

The invention is directed to non-natural yeast able to secrete significant amounts of glucoamylase into a fermentation media. The glucoamylase can promote degradation of starch material generating glucose for fermentation to a desired bioproduct, such as ethanol. The glucoamylase can be provided in the form of a glucoamylase fusion protein having secretion signal that is: derived from at least AA 1-19 of SEQ ID NO: 73, (ii) an amino acid sequence of at least AA 1-19 of SEQ ID NO: 74, (iii) SEQ ID NO: 77 (An C aa), (iv) SEQ ID NO: 75 (Sc IV), (v) SEQ ID NO: 76 (Gg LZ), or (vi) SEQ ID NO: 78(Hs SA).

This invention is in the field of micro-organism and algal cell processing. The invention relates to a method of maximizing migration of micro-organism and/or algal cells to a solvent fraction while simultaneously displacing water in a separate fraction and subsequent extraction of hydrophobic products from the organisms. The invention further relates to a method of sequestration of protein from an aqueous phase to an organic solvent.
