The present disclosure describes a microorganism support structure, including a gas-permeable layer comprising two opposing surfaces; a microorganism adhesive coats at least one surface of the gas-permeable layer; and a microorganism disposed on the microorganism adhesive-coated surface of the layer. The microorganism adhesive enhances the adhesion of the microorganism on the layer compared to a gas-permeable layer that does not have the microorganism adhesive.

Provided are a breast milk-derived Lactobacillus plantarum and use thereof. The breast milk-derived Lactobacillus plantarum, which was screened from healthy breast milk, is classified and named as Lactobacillus plantarum and has an accession number of CGMCC NO.19748. It has strong adhesion, has an inhibitory effect on 8 commonly known pathogenic bacteria, and is susceptible to 8 antibiotics, and also has strong acid resistance and bile salt resistance.

A method of preparing ammonium sulfate includes feeding biosulfur and ammonia produced during anaerobic fermentation into a sulfur-oxidizing microbial reactor to cause sulfur-oxidizing microorganisms to produce sulfuric acid through oxidation of the biosulfur and reacting the produced sulfuric acid with ammonia to produce the ammonium sulfate. A culture medium containing the produced ammonium sulfate and microorganisms can be used as fertilizers.

Compositions and methods are provided comprising acetolactate decarboxylase (ALDC) enzyme variants having higher specific activity. Composition and method are provided where the ALDC variants are used in combination with metal ions to further increase stability and/or activity.

The present invention discloses a method for preserving a probiotic composition, including: providing a bacterial cell suspension, which is one or more bacterial cell suspensions of a bacterium or Saccharomyces boulardii; mixing the bacterial cell suspension with a sodium alginate solution or an alginic acid solution; and adding the mixture to a calcium ion solution until the mixture is immobilized in a shape. The technology of the present invention has the effects of long-term preservation at room temperature and resistance to high temperature, and can be applied to ordinary bacterial strains, without being limited to a small number of bacterial species able to form endospore, and without requiring the strains to be frozen for preservation. The method of the present invention can be applied to the preparation of aquatic feeds, animal feeds, or probiotics that human beings need.
