An active polysaccharide compound nutrient for boosting immunity and relieving fatigue, including 10-12 parts by weight of lentinan, 8-10 parts by weight of laminarin, 5-8 parts by weight of Lycium barbarum, 10-15 parts by weight of Mytilus edulis extract, 10-15 parts by weight of organic selenium protein powder, 8-10 parts by weight of walnut kernel, 3-5 parts by weight of black soybean powder, 2-3 parts by weight of Panax quinquefolius extract, 1-2 parts by weight of Schisandra chinensis, 1-2 parts by weight of Ophiopogon japonicus, 1-2 parts by weight of nutritional yeast, 5-10 parts by weight of L-arabinose, 5-8 parts by weight of xylitol and 0.2-0.3 part by weight of pancreatin. The active polysaccharide compound nutrient is prepared by subjecting raw materials to crushing, mixing, stirring, dissolving with deionized water, concentrating and drying under reduced pressure.

The invention discloses a yeast and lactic acid bacteria combination, comprising saccharomyces and lactic acid bacteria; wherein the saccharomyces comprises Candida ethanolica B-JJ1, and the lactic acid bacteria comprise at least one of Lentilactobacillus buchneri B-JR1, Lactobacillus paracasei B-JR2, Lactobacillus zeae B-JR4, Lactobacillus plantarum B-JR5 and Lactobacillus chiayiensis B-JR6. The yeast and lactic acid bacteria combination is obtained by the processes of inoculum extraction, strain inoculation, combined bacteria optimization and combined bacteria domestication. The fermentation of the yeast and lactic acid bacteria combination provided by the invention can be adopted to prepare bio-enzyme preparation. And the prepared bio-enzyme preparation can be adopted to prepare natural, green, additive-free preservatives with strong antioxidant properties that maintain the activity of plant and animal cells.

Provided herein are recombinant nucleic acid molecules, nucleic acid constructs, fusion enzymes, transformed host cells, and methods for making aroma compounds alpha-ionone or beta-ionone.

Provided herein is a non-naturally occurring microbial organism having a methanol metabolic pathway that can enhance the availability of reducing equivalents in the presence of methanol. Such reducing equivalents can be used to increase the product yield of organic compounds produced by the microbial organism, such as 1,2-propanediol, n-propanol, 1,3-propanediol or glycerol. Also provided herein are methods for using such an organism to produce 1,2-propanediol, n-propanol, 1,3-propanediol or glycerol.
