Abstract: A composition includes a Euglena whole cell biomass and cellular components, including beta-1,3-glucan as at least about 90 percent linear, unbranched beta-1,3-glucan polysaccharide polymers having an average molecular weight of 1.2 to 580 kilodaltons (kDa) and beta-glucan polymer chains having a polymer length of about 7.0 to 3,400 glucose monomers. Residual media remains from a heterotrophic fermentation process that produced the Euglena biomass. The composition may be in different delivery forms and include added immune response inducing components.

Abstract: A composition includes a Euglena biomass lysate having an average particle size of about 2.0 to 500 micrometers and cellular components, including beta-1,3-glucan as at least about 90 percent linear, unbranched beta-1,3-glucan polysaccharide polymers having an average molecular weight of 1.2 to 580 kilodaltons (kDa) and beta-glucan polymer chains having a polymer length of about 7.0 to 3,400 glucose monomers. Residual media remains from a heterotrophic fermentation process that produced a Euglena biomass and the Euglena lysate. Vitamin C is added in an example, and the weight ratio of the beta-1,3-glucan to the added vitamin C is in the ratio of 1:10 to 1:1 and may be in different delivery forms. The composition may include other added immune response inducing components.

Abstract: An animal feed composition includes a feed component made from corn, soy, corn or soy derivatives or byproducts, or grains and an added whole cell Euglena biomass, including beta-1,3-glucan having at least about 90 percent linear, unbranched beta-1,3-glucan polysaccharide polymers with an average molecular weight of about 1.2 to 580 kilodaltons (kDa). Beta-glucan polymer chains have a polymer length of about 7.0 to 3,400 glucose monomers. The whole cell Euglena biomass has at least 30 percent beta-1,3-glucan and residual media remaining from a heterotrophic fermentation process and is about 0.0001 to 0.0124 percent of the composition. It is possible to add a Euglena lysate.

Abstract: A composition includes a Euglena lysate and cellular components and residual media remaining from a fermentation process that produced a Euglena biomass and the Euglena lysate. The cellular components may include one or more beta-glucan polymer chains having a molecular weight of 1.2 to 580 kilodaltons (kDa).

Abstract: A method for producing a purified beta-1,3-glucan includes growing a biomass from genus Euglena organism and dewatering the grown biomass. The biomass is lysed to form a lysed biomass, which is washed and dewatered to produce a beta-1,3-glucan. The beta-1,3-glucan is dried to produce the purified beta-1,3-glucan.

Abstract: A process to prepare propionic acid comprises preparing a fermentation broth of water; at least 30 weight percent hydrolyzed corn mash solids, hydrolyzed sugar cane mash solids, or a combination thereof, based on the combined weight of the fermentation broth as a whole; and propionibacteria; without including the typical, frequently very costly supplementation with vitamin and mineral packages. Surprisingly, these mash solids, which must often be disposed of following syrup production, are capable of supplying the nitrogen, micronutrients, vitamins and minerals known to be needed for propionibacteria fermentation, making their sole or significant use as fermentation mediums far more economical and therefore desirable than other fermentation mediums which require supplementation.

Abstract: A process for producing (R)-?-arylalanines is described. The process converts (S)-?-arylalanine to (R)-?-arylalanine using phenylalanine aminomutase and amino acid racemase. The (R)-?-arylalanine product can be used to form pharmaceutically useful drugs. Also disclosed are DNA sequences encloding phenylalanine aminomutase and amino acid racemase enzymes, sequences for PCR primers of the DNA sequences, and sequences for expressed aminomutase and amino acid racemase enzymes.
