Expression of Trichoderma reesei cellulases in the fungus Ashbya gossypii

Construction of a flocculent Saccharomyces cerevisiae strain secreting high lev...

A flocculent Saccharomyces cerevisiae strain secreting Aspergillus niger β-galactosidase activity was constructed by transforming S. cerevisiae NCYC869-A3 strain with plasmid pVK1.1 harboring the A. niger β-galactosidase gene, lacA, under the control of the ADH1 promoter and terminator. Compared to other recombinant S. cerevisiae strains, this recombinant yeast has higher levels of extracellular β-galactosidase...

Expression of a fungal hydrophobin in the Saccharomyces cerevisiae cell wall : ...

The aim of this work was to modify the cell surface properties of Saccharomyces cerevisiae by expression of the HFBI hydrophobin of the filamentous fungus Trichoderma reesei on the yeast cell surface. The second aim was to study the immobilization capacity of the modified cells. Fusion to the Flo1p flocculin was used to target the HFBI moiety to the cell wall. Determination of cell surface characteristics with ...

Construction of a flocculent brewer's yeast strain secreting Aspergillus niger ...

One way of improving heterologous protein production is to use high cell density systems, one of the most attractive being the flocculating yeast production system. Also, lactose is available in large amounts as a waste product from cheese production processes. The construction of flocculent and non-flocculent brewer's yeast strains secreting β-galactosidase and growing on lactose is presented. A plasmid was co...
