303 results about "Yeast form" patented technology

Yeasts do not form a single taxonomic or phylogenetic grouping. The term "yeast" is often taken as a synonym for Saccharomyces cerevisiae, but the phylogenetic diversity of yeasts is shown by their placement in two separate phyla: the Ascomycota and the Basidiomycota.

Methods of synthesizing heteromultimeric polypeptides in yeast using a haploid mating strategy

ActiveUS20060270045A1Enhance full-length product generationIncrease secretionFungiMicrobiological testing/measurementBiotechnologyMating
Methods are provided for the synthesis and secretion of recombinant proteins preferably large mammalian proteins or hetero-multimeric proteins at high levels and for prolonged time in polyploid, preferably diploid yeast. These methods use various mating competent yeast, including Pichia. In a preferred embodiment, a first expression vector is transformed into a first haploid cell; and a second expression vector is transformed into a second haploid cell. The transformed haploid cells, each individually synthesizing a non-identical polypeptide, are identified and then genetically crossed or fused. The resulting diploid strains are utilized to produce and secrete fully assembled and biologically functional hetero-multimeric protein.

A method and system to produce biodiesel from a combination of corn (maize) and other agro feedstock may be simarouba, mahua, rice, pongamia etc. Germ is separated (either by wet process or dry process) from corn, crude corn oil extracted from germ and corn starch milk / slurry is heated and cooked in jet cooker to about 105 degree Celsius, enzymes added to convert starch into fermentable sugars in liquification and saccharification process and rapidly cooled down to about 30 degree Celsius. Simarouba fruits syrup, mahua syrup is mixed with corn starch milk (after saccharification). When yeast is added the fermentation takes place for about 72 hours. Thereafter the fermented wash is distilled to produce ethanol. Water consumed in dry process is very less compared to traditional wet process system. Corn oil and mixture of other oils is fed into transesterification (reaction) vessels where ethanol with catalyst, usually sodium hydroxide is added and reaction takes place for about a period of 2-8 hours. Crude biodiesel and crude glycerin as by-products is produced. Excess ethanol removed by distillation process. Crude biodiesel washed with warm water to remove residual soaps or unused catalyst, dried and biodiesel stored for commercial use. Oil extracted from spent bleach mud (used sodium bentonite), a waste product of edible oil refineries may also be utilized for economical production of biodiesel in combination of corn oil and ethanol.

Methylotroph producing mammalian type sugar chain

This invention is to provide a process for producing a glycoprotein comprising a mammalian type sugar chain, characterized in that the process comprises introducing an α-1,2-mannosidase gene into a methylotrophic yeast having a mutation of a sugar chain biosynthesizing enzyme gene, so that the α-1,2-mannosidase gene is expressed under the control of a potent promoter in the yeast; culturing in a medium the methylotrophic yeast cells with a heterologous gene transferred thereinto; and obtaining the glycoprotein comprising a mammalian type sugar chain from the culture. Using the newly created methylotrophic yeast having a sugar chain mutation, a neutral sugar chain identical with a high mannose type sugar chain produced by mammalian cells such as human cells, or a glycoprotein comprising such a neutral sugar chain, can be produced in a large amount at a high purity. By introducing a mammalian type sugar chain biosynthesizing gene into the above-described mutant, a mammalian type sugar chain, such as a hybrid or complex, or a protein comprising a mammalian type sugar chain can be efficiently produced.
