One of problems is to provide a feed composition having both immunostimulatory action and mold toxin adsorbing action. Another one of the problems is to provide a technique for minimizing decomposition of a feed composition made using yeast. Yet another one of the problems is to provide a method of inexpensively manufacturing the above-mentioned feed composition.

The feed composition is obtained by inclusion of nucleic acid having molecular weights ranging from 5,000 to 100,000, a yeast cell wall component/yeast cell wall components, and ligno sulfonic acid. A feed composition may be manufactured by supplying nucleic acid and a yeast cell wall component that are both derived from a raw material, yeast. To supply the nucleic acid and a yeast cell wall component/yeast cell wall components from the yeast, the yeast may be subjected to alkaline treatment to prepare the nucleic acid and enucleated yeast.

Methods and compositions are provided for reducing off-flavor in aquatic species or in aqueous systems. Microbial biomass or its derivatives is provided in the form of a feed composition or into the water in an aquaculture production system or other aqueous system, thereby modulating the level of one or more off-flavor producing compounds.

There is provided a novel Lactobacillus fermentum strain (Accession No. KCTC 14105BP) and a composition for preventing or treating a metabolic disease including the same. A Lactobacillus fermentum according to the present invention may inhibit fat accumulation in white adipose tissue and increase anti-inflammatory cells. The Lactobacillus fermentum strain may exhibit excellent blood glucose improvement effect, and in particular, may reduce a fasting blood glucose level. The Lactobacillus fermentum strain may effectively ameliorate insulin resistance by improving glucose tolerance and increasing insulin sensitivity. In addition, the Lactobacillus fermentum strain may regulate a concentration of metabolic hormones and adipokines in blood. Therefore, the Lactobacillus fermentum strain may be usefully used to prevent and treat a metabolic disease such as obesity.
