The subject invention provides materials and methods for reducing deleterious atmospheric gases, such as greenhouse gases (GHGs) by enhancing utilization and storage of carbon in plants, as well as increasing the sequestration of carbon in plant and soil matter in the form of degradation-resistant organic polymers.

The present invention relates to an oleaginous yeast Yarrowia lipolytica sur2 mutant strain and a method for producing and secreting, onto cell surfaces, sphingoid-based precursors, sphingosine and sphingolipids by using same. It has been identified that when a ceramidase gene is additionally introduced into a Ylsur2 deficient mutant strain, the secretion and production of dihydrosphingosine and sphingosine are increased and, further, it is has been identified that when a Ylsld1sur2 double mutant strain in which a SLD1 gene is additionally deficient in a Ylsur2 deficient mutant strain is prepared, growth recovery and sphingosine and human-type glucosylceramide secretion and production are increased.

The present invention relates to the unexpected discovery of a new strain of yeast, dubbed GY7B, which is related to, but genetically and phenotypically distinct from, Lachancea thermotolerans. The invention provides methods of brewing sour beer using GY7B, wherein the methods do not require use of lactic acid or lactic acid producing bacteria.

This application describes consortium between fungi and algae, where the algae are incorporated within hyphae of the fungi. The fungi, the algae, or both can be modified to express heterologous lipid synthesizing enzymes. Incorporation of algae into fungi facilitates harvesting of the algae and products produced by the consortia. Such consortia are robust. For example, the fungi and algae can symbiotically provide nutrients to each other and are tolerant of environmental stresses.

The present invention relates to a method for processing a composition comprising fructan and sucrose, comprising the step of incubating a composition comprising fructan and sucrose, preferably inulin and sucrose, with at least one yeast selected from the group consisting of Saccharomyces, and Kluyveromyces. Incubation with these yeasts results in the breakdown of free sugars such that purified fructan compositions are obtained.

A physiologically acceptable composition comprising (i) at least one component selected from the group consisting of inactivated S. boulardii yeasts, S. boulardii lysates, S. boulardii cell wall components, and S. boulardii extracts, further comprising (ii) at least one component selected from the group of inactivated S. cerevisiae yeasts, S. cerevisiae lysates, S. cerevisiae cell wall components and S. cerevisiae extracts and further comprising (iii) at least one component selected from the group consisting of inactivated K. marxianus yeasts, K. marxianus lysates, K. marxianus cell wall components and K. marxianus extracts. The invention further relates to the composition for use as a medicament, as a food additive or functional ingredient for nutraceuticals, food for special medical purposes, cosmeceuticals and functional foods, and as a feed additive of functional ingredient in animal nutrition, as ingredient for topical application.

The present invention is directed to compositions comprising hydrolase-secreting bacteria and fermenting microorganisms and use thereof, such as for fermentative production of ethanol.

Methods of and system for growing and maintaining an optimized/ideal active yeast solution in the yeast tank and fermenter tank during the fermentation filling cycle are provided. A new yeast stage tank is used between the yeast tank and the fermenter tank allowing yeast to rapidly produce a huge amount of active young yeast cells for a fermenter during the filling period. A measurable and useful controlling factor, % DT/% Yeast by weight ratio (or food to yeast ratio), is used (e.g., % DT=glucose), which offers information on the health status of the yeast. The controlling factor is used to control the status of the yeast throughout the entire process.

A physiologically acceptable composition comprising (i) at least one component selected from the group consisting of S. boulardii yeasts, S. boulardii lysates, S. boulardii cell wall components, and S. boulardii extracts, further comprising (ii) at least one component selected from the group of S. cerevisiae yeasts, S. cerevisiae lysates, S. cerevisiae cell wall components and S. cerevisiae extracts and further comprising (iii) at least one component selected from the group consisting of K. marxianus yeasts, K. marxianus lysates, K. marxianus cell wall components and K. marxianus extracts. The invention further relates to the composition for use as a medicament, as a food additive or functional ingredient for nutraceuticals, food for special medical purposes, cosmeceuticals and functional foods, and as a feed additive of functional ingredient in animal nutrition, as ingredient for topical application.

The present invention relates to a yeast strain likely to be obtained by hybridizing a strain S1 with a strain S2, said yeast strain presenting, according to test A, the following characteristics: fermentation kinetics from 15 to 22 days at a temperature of 24? C.; and resistance with an alcoholic strength of more than or equal to 15% v/v; and a nitrogen requirement of less than or equal to 200 ppm,
to the method of producing this strain and to its use.
