Genetically modified microorganisms useful in fermentation and methods of using such microorganisms are provided. Such microorganisms contain a [GAR+] prion or are modified to contain a [GAR+] prion. Exemplary microorganisms include yeast such as S. cerevisiae. The microorganisms can be further modified to convert xylose and/or arabinose. Methods of fermentation using such microorganisms exhibit improved fermentation efficiency and improved microorganism viability.

The current invention concerns a new B. licheniformis strain with strong inhibition of C. perfringens and its use as probiotic.

The present disclosure relates to using a source of one or more monosaccharides derived from a pulp or paper mill waste by-product for propagating microorganisms (e.g., yeast or bacteria). If desired, after propagation, the microorganisms can then be used to ferment one or more monosaccharides derived from a pulp or paper mill waste by-product into one or more biochemicals. Optionally, a stillage composition can be included in propagation medium to facilitate propagation and/or a stillage composition can be used to facilitate enzymatic hydrolysis of oligosaccharides and/or polysaccharides in a pulp or paper mill waste by-product to form monosaccharides.

In some embodiments, the invention provides a method for converting of a flue gas desulfurization (FGD) waste product to a gypsum-enriched product by fostering growth of sulfur oxidizing bacteria (SOB) in the FGD waste product. Also provided are isolated sulfur oxidizing bacteria cultures as well as kits comprising an isolated sulfur oxidizing bacteria culture and written instructions for fostering the growth of the isolated sulfur oxidizing bacteria culture in FGD waste product to product a gypsum-enriched product.
