Abstract: A novel Lactobacillus plantarum and use thereof are disclosed, which fall within the technical field of microorganisms. The Lactobacillus plantarum tlj-2014 is deposited in China General Microbiological Culture Collection Center (CGMCC) under CGMCC Accession No. 9405. With the strain, the lactic acid production rate can be up to 35 g/L/d, and the concentration of lactic acid after 71 hrs of fermentation is up to 95 g/L. The Lactobacillus plantarum is acid tolerant, survives well at pH 1.80, can degrade the nitrite quickly with a decomposition capability of up to 9.8 mg/h/kg, and is tolerant to 1% bile salt. When the strain is used in production of pickles, the nitrite concentration is less than 5 mg/kg throughout the entire fermentation process, which is far below the content specified in the national standard GB2714-2003.
Abstract: The present invention discloses a yeast strain with high yield of glutathione, and belongs to the technical field of microorganisms. Saccharomyces cerevisiae tlj2016 provided in the present invention has been deposited in China General Microbiological Culture Collection Center of Microbe Preservation Management Committee, with a preservation number of CGMCC No. 12789. The strain can tolerate glucose with tolerance capability reaching 300 g/L, and has tolerance capability against L-cysteine that is far higher than that of the starting strain, contributing to the production of glutathione at conditions of high concentrations of glucose, with a final concentration of GSH produced through fermentation in a 5-L fermentation tank reaching 3308 mg/L.
Abstract: The present invention relates to a mutant strain of Trichodema reesei, namely, CCTCC No: M 2013540, that produces cellulase with high enzyme activity, and a method of producing thereof. The enzyme activity of the cellulase was as follows: Filter Paper Activity (FPA): 792 U/mL, Endo-1,4-?-D-glucanase (EG): 1389 U/mL, Exo-1,4-?-D-glucannase (CBH): 680 U/mL, ?-1,4-glucosidase (BG): 486 U/mL.
Abstract: The present invention relates to a Lactobacillus plantarum capsule and use thereof, and belongs to the technical field of microbe feed additives. The Lactobacillus plantarum capsule consists of a wall material, Lactobacillus plantarum, a cryoprotectant, stachyose, and Morchella esculenta zymolytic powders; wherein the wall material is composed of zymolytic soybean protein isolate, chitosan, xanthan gum, carrageenin, glycerin and trehalose, and when formulated into a mixed solution, the above substances have concentrations of 7 to 10% zymolytic soybean protein isolate, 1 to 2% chitosan, 1 to 3% xanthan gum, 0.1 to 0.5% carrageenin, 0.3 to 1% glycerin, and 0.5 to 2% trehalose. The Lactobacillus plantarum capsule of the present invention enhances resistance of the capsule to gastric acid, has very good enteric solubility, besides, it can effectively inhibit the growth of pathogenic germs to improve immunity, decrease incidence of diseases in livestock and poultry, and improve the breeding quality and benefit.
