The present invention discloses compositions and methodologies for the utilization of probiotic organisms in therapeutic compositions. More specifically, the present invention relates to the utilization of one or more species or strains of lactic acid-producing bacteria, preferably strains of Bacillus coagulans, for the control of gastrointestinal tract pathogens, including antibiotic-resistant gastrointestinal tract pathogens, and their associated diseases by both a reduction in the rate of colonization and the severity of the deleterious physiological effects of the colonization of the antibiotic-resistant pathogen. In addition, the present invention relates to the utilization of therapeutic compounds comprised of lactic acid-producing bacteria and anti-microbial agents such as antibiotics, anti-fungal compounds, anti-yeast compounds, or anti-viral compounds. The present invention also discloses methodologies for: (i) the selective breeding and isolation of probiotic, lactic acid-producing bacterial strains which possess resistance or markedly decreased sensitivity to anti-microbial agents (e.g., antibiotics, anti-fungal agents, anti-yeast agents, and anti-viral agents); and (ii) treating or preventing bacteria-mediated infections of the gastrointestinal tract by use of the aforementioned probiotic bacterial strains with or without the concomitant administration of antibiotics. While the primary focus is on the treatment of gastrointestinal tract infections, the therapeutic compositions of the present invention may also be administered to buccal, vaginal, optic, and like physiological locations.

The invention provides a bacillus subtilis for effectively degrading grease. The bacillus subtilis 6-loil is preserved at Guangdong Province Microbiological Culture Collection Center on December 22, 2016. The preservation number is GDMCC No. 60134. The bacillus subtilis 6-loil provided by the invention can utilize the grease as a growth carbon source, can normally grow under an environment of higher grease content and has a capacity of efficiently degrading grease. The bacillus subtilis 6-loil provided by the invention can be compounded with bacillus coagulans, brewer yeast and carrier ingredients so as to be prepared into a kitchen garbage disposal fungicide. The prepared kitchen garbage disposal fungicide can adapt to the condition of high grease content of the domestic kitchen garbage, so that the condition of failure in aerobic composting caused by the reduction of microbial activity resulted from the microorganism wrapped by the grease in aerobic composting can be effectively avoided and the bacillus subtilis can meet the requirement of the domestic kitchen garbage aerobic composting. The bacillus subtilis 6-loil also can be applied to the fields of soil oil stain treatment, biosurfactant production, biological detergent preparation, and the like.

The invention relates to anthropogenic lactobacilus fermentum grx07 with a protection role on chronic alcoholic liver damage and application thereof. The lactobacilus fermentum grx07 strain disclosed by the invention is a probiotic strain separated from intestinal tracts of people in a Rugao longevity village of Jiangsu, the strain is preserved in China General Microbiological Culture Collection Center, and the preservation number is CGMCC No.8874. The lactobacilus fermentum grx07 strain has significant in vitro antioxidant ability and pathogenic bacteria inhibition ability, the rat blood fat of chronic alcoholic liver damage and the toxin level in serum can be significantly reduced, expression of liver inflammatory cytokines is reduced, the inflammatory reaction of the liver is relieved, the expression quality of antioxidant specific protein Nrf2 of the liver is increased, and the liver cell apoptosis percentage is reduced. Therefore, the anthropogenic lactobacilus fermentum grx07 has a significant protective effect on the chronic alcoholic liver damage.

The present invention describes new and distinct strains of higher Basidiomycetes mushrooms grown in submerged cultures. Specifically, the new strain of species of the genus Tremella offer superior yields of one-cell biomass and exocellular heteropolysaccharide glucuronoxylomannan, niacin and essential amino acids.

The invention relates to a method for breeding a high-nucleic acid yeast from Saccharomyces cerevisiae, which comprises the following steps: culturing a large amount of preserved Saccharomyces cerevisiae strains in an appropriate yeast growth medium, breeding initial strains, carrying out secondary screening on the initial strains and selecting growth media to obtain high-nucleic acid yeast strains for industrial production. Virulence tests show that thalli and metabolites can not cause intoxicating reactions. The Saccharomyces cerevisiae used in the method is one firstly recommended by Ministry of Health P.R.China for health food among fungi strains. The high-nucleic acid yeast bred from the Saccharomyces cerevisiae is used for the industrial production of nucleic acid, the bred high-nucleic acid yeast proves to be Saccharomyces cerevisiae by another microbiological assay and belongs to the traditional strains for producing beer, and the nucleic acid content of the thalli can be up to 12-14%(W / W) in the optimal culture condition. The method can be widely used for large-scale industrial production, and the prepared nucleic acid can be trustingly used in fields of health food, medicaments, infant food and the like.

The invention relates to multi-bacterium microbial compound preparations for aquaculture and a preparation method thereof. The multi-bacterium microbial compound preparations are characterized by comprising the following steps of: preparing seed culture solution by performing single strain culture on rhodoplanes elegans, pichia fermentans lodder, bacillus natto swamura, bacillus subtills, lactococcus lactis and bifidobacterium sp respectively; inoculating the seed culture solution onto the same culture medium; and then culturing the seed culture solution by a fermentation tank, and naturally reducing a pH value of the seed culture solution to 3.0 to 3.5 to obtain the multi-bacterium microbial compound preparations, wherein the bacterial content of the pichia fermentans lodder in the preparations is more than or equal to 0.1*10<9>cfu / ml; the bacterial content of the other strains is more than or equal to 5.0*10<9>cfu / ml. The multi-bacterium microbial compound preparations for aquaculture can improve the ecological environment of aquatic animals, prevents and treats diseases, reduces the emergency condition of the animals, improves the quality of the aquatic animals, and shortens a listed period.

A fish-sourced aeromonas hydrophila disease antagonistic strain is screened out, cultivated and added into a feed or a medicine as probiotics. The antagonistic strain is a novel antagonistic strain which is high in biological activity stability and high in specificity, is safe for cultured fish and environment, can be used as the probiotics strain for preventing and treating aeromonas hydrophila caused explosive hemorrhagic disease in large freshwater fish farming, and can be used as the main strain to prepare a microbial preparation.

The invention discloses a detection method for drug resistant genes of Klebsiella pneumoniae against belta-lactamase, pertaining to the technical field of gene detection methods. The detection method comprises the following steps: 1. Klebsiella pneumoniae strains of inpatients are selected and sampling for backup is carried out after strain identification is carried out to all strains using bacteria identifying apparatus; 2. the sensitivity of antibacterials is determined by adopting the micro dilution method so as to judge the sensitivity of antibiotic; and 3. drug resistant genes are detected by adopting a PCR method and belta-lactamase drug resistant genes are checked and DNA positive strains are selected for carrying out sequencing analysis. The detection method finds the drug resistant genes resulting in the resistance of Klebsiella pneumoniae to belta lactam drugs by carrying out a systematical and complete research on the drug resistant mechanism of the Klebsiella pneumoniae, thus having important value for instructing the clinical and reasonable use of antibacterials, being capable of reducing the infection rate in a hospital, reducing mortality rate and saving social medical resources, and having good social and economic benefits.
