摘要:
The present application provides genetically modified fungal organisms that produce enzyme mixtures exhibiting enhanced hydrolysis of cellulosic material to glucose, enzyme mixtures produced by the genetically modified fungal organisms, and processes for producing glucose from cellulose using such enzyme mixtures.
摘要:
This invention relates to a process of obtaining hybrid strains obtained by protoplast fusion of Saccharomyces cerevisiae and Torulaspora delbrueckii and their use in fully conducting alcoholic fermentations of red and white wine as well as their use as restarter strains in the rectification of stuck or sluggish fermentations. This new strains combine characteristics of both parental strains, namely the sugar consumption displayed by S. cerevisiae, intermediate ethanol resistance of the one displayed by parental strains and aromatic profile similar to T. delbrueckii. This invention further refers to the three strains obtained as well as to the consortium of the three.
摘要:
The present invention provides methods and compositions for producing and screening combinatorial libraries of multimeric proteins. The present invention relies on the use of filamentous fungal heterokaryons that are produced using two or more parent strains into which a population of DNA molecules encoding variants of a multimeric protein have been introduced.
摘要:
A gene has been isolated which encodes cytochrome b5 (CYTb5) protein of the omega-hydroxylase complex of C. tropicalids 20336. Vectors including this gene, and transformed host cells are provided. Methods of increasing the production of a CYTb5 protein are also provided which involve transforming a host cell with a gene encoding this protein and culturing the cells. Methods of increasing the production of a dicarboxylic acid are also provided which involve increasing in the host cell the number of genes encoding this protein.
摘要:
The invention relates to a heterokaryotic filamentous fungus host capable of producing a heterologous heterodimer comprising at least two subunits. The heterokaryon contains a first and second nucleus; each nucleus contains an expression system for one subunit of the heterodimer. The heterokaryon is prepared by culturing together a first fungus host strain and a second fungus host strain that is homozygous with the first fungus host strain with respect to all heterokaryon compatibility alleles, wherein the first and second fungus host strains are cultured together under conditions wherein neither the first nor the second fungus strain can survive unless the heterokaryotic host is formed.
摘要:
Insecticidal peptides comprising the amino acid sequence CX X X RECGSCX CNX WKGKCEX (SEQ ID NO 1), where X , X , X , X , X and X are any amino acid; or a fragment thereof, or a homologue or variant or derivative of any of these are described and claimed together with nucleotide sequences encoding these peptides. They may be applied as insecticidal compounds in the form of compositions, or expressed in host cells in particular plant cells. Transgenic plants which express peptides of the invention are described.
