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 are a Lactobacillus helveticus strain and a composition for preventing or treating inflammatory disease containing the same. The Lactobacillus helveticus strain (Accession No. KCTC 14110BP) according to the present invention alleviates symptoms of inflammatory bowel disease, such as weight loss and bowel length reduction, and it does not have side effects that have been seen with existing drug treatment. Therefore, the Lactobacillus helveticus strain can be effectively used for the treatment and prevention of inflammatory disease, particularly inflammatory bowel disease.

The disclosure provides novel microorganisms, such as Lactobacillus sp., Bifidobacterium sp., and Veillonella sp., and compositions thereof for improving athletic performance, enhancing exercise endurance, improving physical recovery from exercise, and reducing inflammation in a subject in need thereof.

An efficient multi-dimensional carbon source and a method for preparing the same are disclosed. The efficient multi-dimensional carbon source includes the following components by weight: 30%-50% of alcohols, 20%-30% of biomass digestive liquid, 1%-10% of carbohydrates, 0.5% of polymethyl methacrylate and balance of water. A method for preparing the efficient multi-dimensional carbon source is further disclosed.

Provided are a lactic acid bacteria culture medium comprising red ginseng-derived dietary fiber; and a method for culturing lactic acid bacteria by using same, wherein red ginseng-derived dietary fiber is used in a lactic acid bacteria culture medium so that the number of viable lactic acid bacteria can be increased and the culturing thereof can be improved, and the method uses the culture medium so as to improve culturing under the same conditions, and thus is advantageous in terms of cost.
