The present invention relates to yeast strains of the species Saccharomyces pastorianus with the useful characteristic of producing low levels of diacetyl during fermentation. Also provided are methods of producing a malt and/or cereal based beverage with these strains, as well as beverages produced by this method.

The present disclosure discloses a method for preparing natural delta-decalactone and delta-dodecalactone by bioreduction of Massoia Oil, which comprises (1) Strain activation, (2) Preparation of seed culture solution, (3) Fermentation and conversion, (4) Extraction, (5) Solvent recycle, and (6) Rectification.

A yeast cell for use in the treatment and/or alleviation of allergy and/or symptoms caused by allergy, wherein the yeast cell has been treated with electromagnetic waves in the range of 1 GHz to 300 GHz, or said yeast cell has been grown from a yeast cell treated with electromagnetic waves in the range of 1 GHz to 300 GHz, and composition comprising such a yeast cell.

Disclosed are microbial compositions having unique combinations of microbial species which are used in plant material recycling and retting. Also disclosed microbial inoculants which contains such a microbial composition, water, and an optional carbon source. The microbial compositions and microbial inoculants are particularly useful in recycling high lignin-content plant material. Methods of making and methods of using the microbial compositions and the microbial inoculants are also described.

A yeast cell for use in the treatment and/or alleviation of inflammation and/or symptoms caused by inflammation, wherein the yeast cell has been treated with electromagnetic waves in the range of 1 GHz to 300 GHz, or said yeast cell has been grown from a yeast cell treated with electromagnetic waves in the range of 1 GHz to 300 GHz, and composition comprising such a yeast cell.

A yeast cell for use in the treatment and/or alleviation of allergy and/or symptoms caused by allergy, wherein the yeast cell has been treated with electromagnetic waves in the range of 1 GHz to 300 GHz, or said yeast cell has been grown from a yeast cell treated with electromagnetic waves in the range of 1 GHz to 300 GHz, and composition comprising such a yeast cell.
