The present disclosure concerns a method of obtaining a composition having yeast proteins derived from yeast protoplasts. The present disclosure also includes compositions comprising yeast proteins derived from yeast protoplasts, edible products derived from said composition as well as usages thereof.

The present disclosure provides a yeast composition enriched in at least one vitamin and/or in at least one sterol that can be used to provide antioxidant activity. The yeast composition can be used to prevent or limit the oxidation of an edible or a drinkable product. The yeast composition can be used to increase the robustness of a fermentative organism during a fermentation. The yeast composition can be used to provide a source of nutrition to a fermentative organism during a fermentation.

The present disclosure provides yeasts, which can be recombinant yeast host cells, exhibiting prolonged persistence when submitted to a plurality of fermentation cycles. The yeasts exhibit at least one of the following phenotypic trait: a fast settling phenotype, a rugose phenotype, an improved invertase activity, triploidy, increased signaling in a RAS/cAMP/PKA pathway or combinations thereof.

The present disclosure concerns recombinant yeast host cells having a first genetic modification for downregulating a first metabolic pathway that converts NADP + to NADPH, as well as a second genetic modification for upregulating a second metabolic pathway that converts NADP + to NADPH. The second genetic modification allows the expression of a glyceraldehyde-3-phosphate dehydrogenase lacking phosphorylating activity, which can, in some embodiments, be from enzyme commission 1.2.1.9 or 1.2.1.90. The second pathway is distinct from the first metabolic pathway. The present disclosure also concerns a process for making and improving the yield of a fermented product, such as ethanol, using the recombinant yeast host cell.

A spreading device, a powder-like mixture composition and a method tor spreading the composition for control or prevent forest pathogens on tree stumps are disclosed.

The present disclosure concerns a process for fermenting a biomass with a reduced dose of a purified exogenous enzyme (which can be, for example a purified exogenous glucoamylase). The process comprises contacting a biomass (which may comprise starch) with a recombinant yeast host cell. The recombinant yeast host cell has a genetic modification for expressing a heterologous polypeptide having starch or dextrin hydrolase activity (which may be, for example, from a glucoamylase). The nucleic acid molecule encoding the heterologous polypeptide having starch or dextrin hydrolase activity comprises allowing the secretion of the heterologous polypeptide.

The present disclosure relates to a seed of a plant, a seedling or a plant derived from the seed containing an increased internal concentration of glycine-betaine compared to untreated controls. The present disclosure further relates to a method to produce a seed of a plant, a seedling or a plant derived from said seed containing an increased internal concentration of glycine-betaine which will confer to the seed, seedling or plant derived from said seed an enhanced germination potential and/or increased tolerance against various environmental stresses compared to untreated controls. The present disclosure further relates to uses of glycine-betaine for enhancing the germination potential of a seed and/or for increasing the tolerance of a seed against environmental stress. The present disclosure also relates to seedlings and plants, or parts thereof, derived from a seed of the present invention having an increased international concentration of glycine-betaine. The present disclosure further relates to seedlings or plants, or parts thereof, obtainable by the methods of the present invention.

The present disclosure concerns a flavored porous material as well as a flavored beverage obtained from using such flavored porous material. The flavored porous material can be obtained from contacting a flavored solution (which can be obtained from fermentation) with the porous material. The flavored beverage can be obtained from contacting the flavored porous material with an untreated beverage.

The present disclosure concerns a process for fermenting a biomass with a reduced dose of a purified exogenous enzyme (which can be, for example a purified exogenous glucoamylase). The process comprises contacting a biomass (which may comprise starch) with a recombinant yeast host cell. The recombinant yeast host cell has a genetic modification for expressing a heterologous polypeptide having starch or dextrin hydrolase activity (which may be, for example, from a glucoamylase). The nucleic acid molecule encoding the heterologous polypeptide having starch or dextrin hydrolase activity comprises allowing the secretion of the heterologous polypeptide.

The present invention relates to host cells and their use wherein the host cells are capable of producing D-ribulose and incapable of or have a reduced capability of converting D-ribulose to a molecule other than ribitol, wherein the host cells comprise a heterologous nucleic acid sequence encoding a polypeptide capable of converting D-ribulose to ribitol with a cofactor preference for NADPH.
