The present application relates to a fructose-4-epimerase variant exhibiting tagatose conversion activity and a method for preparing tagatose using the same.

The invention relates to a Novosphingobium sp. SJB007 and an application thereof in removal of phosphorus from wastewater, belonging to the technical field of environmental microorganisms. One aspect of the invention provides a Novosphingobium sp. SJB007 with an access number of CGMCC (China General Microbiological Culture Collection Center) No. 21177. Another aspect of the invention provides an application of the Novosphingobium sp. SJB007 in removal of phosphorus from wastewater. The efficient phosphorus-accumulating strain Novosphingobium sp. SJB007 provided by the invention has a high removal rate of more than 97% when the concentration of phosphorus in the wastewater is 10-30 mg/L under an appropriate condition.

The present invention relates to a microorganism which can act as a biomarker of alcoholic fatty liver disease, and relates to a pharmaceutical composition for preventing or treating alcoholic fatty liver disease, a food composition for preventing or improving alcoholic fatty liver disease, or a probiotics composition for preventing or improving alcoholic fatty liver disease, comprising the strain as an active ingredient.

Endophytic microbial strains as biocatalysts isolated from fresh plant samples, their compositions, and methods of use thereof to enhance the growth and/or yield of a plant in the presence of reduced (synthetic or otherwise) nitrogen and phosphorus fertilizers are provided. The selected endophytic microbial strains serve as biocatalysts to solubilize organic (proteinaceous) nitrogen otherwise unavailable to plants for their nutritional needs. In addition, selected endophytic microbial strains serve as biocatalysts to solubilize mineral-P and mineralize organic-P otherwise unavailable to plants for their nutritional phosphate needs. Thus defined, biocatalysts will serve to replace or reduce the requirement of (synthetic or otherwise) nitrogen and phosphorus fertilizers. Also provided are materials and methods for inoculating plants with these biocatalysts at carefully selected inoculum densities to reliably reduce the amount of nitrogen and phosphorus fertilizers by 30-50% thus accomplishing optimal yields in a cost-effective manner.
