标 题:Variant of oleaginous yeast and its use for the production of lipids

摘要:The present invention relates to a variant of oleaginous yeast of the species Trichosporon oleaginosus characterized by mutations affecting cell wall synthesis that change the morphology thereof with respect to the wild-type strain of the same species. In particular, thanks to said mutations, cell aggregates are formed which, with respect to the wild-type strain of the same species, lower the viscosity of the culture broth, are more easily separable therefrom and thus make their recovery easier. Said variant of oleaginous yeast of the species Trichosporon oleaginosus is also characterized by yields of oleaginous cellular biomass and intracellular accumulation of lipids that are similar or even higher than those of the wild-type strain. Further, the present invention relates to a process for the production of lipids through said variant of oleaginous yeast of the species Trichosporon oleaginosus . The lipids thus obtained can be advantageously used as synthesis intermediates, particularly in the so-called “green chemistryâ€? sector, or in the production of biofuels such as, for example, “biodieselâ€? or “green dieselâ€?, which can be used as such, or mixed with other fuel for transportation.

摘要:Process for the production of sugars from biomass derived from guayule plants comprising: subjecting said biomass to a biological pretreatment in the presence of at least one ligninolytic fungus obtaining a liquid phase comprising sugars and a first solid residue: subjecting said first solid residue to hydrolysis in the presence of at least one diluted inorganic acid obtaining a first hydrolysate comprising sugars and a second solid residue; subjecting said second solid residue to enzymatic hydrolysis obtaining a second hydrolysate comprising sugars and a third solid residue. The sugars thus obtained can be advantageously used as sources of carbon in fermentation processes for producing alcohols (e.g., ethanol, butanol), lipids, diols (e.g., 1,3-propanediol, 1,3-butanediol, 1,4-butanediol, 2,3-butanediol), or in chemical synthesis processes for producing other intermediates or chemical products (e.g., furfural). Said alcohols and lipids can be advantageously used in turn in the production of biofuels (e.g., biodiesel or “green dieselâ€?), which can be used as such, or mixed with other fuels for transportation, while said diols can be used in the production of products such as bio-butadiene which can in turn be used for manufacturing rubbers (e.g., polybutadiene or copolymers thereof). Said uses are particularly important in the case of a biorefinery.

标题:Polynucleotides encoding an acetyl-CoA acetyltransferase from Hevea brasiliensis, related products, and methods

摘要:The instant invention relates to bioproduction of isopentenyl diphosphate within the latex of the rubber tree, Hevea brasiliensis . Isopentenyl diphosphate (IPP) synthesis from acetate is mediated by a set of enzymes, acetyl-coA acetyltransferase, HMG-coA synthase, HMG-coA reductase, mevalonate kinase, phosphomevalonate kinase and mevalonate diphosphate decarboxylase, encoded by six genes isolated as expressed sequence tag (EST) cDNAs from Hevea brasiliensis latex. In addition, a variant sequence of one of these enzymes, acetyl-coA acetyltransferase, has been found.
