ActiveCN102963985BIncrease dissolved oxygenRaise antibody levelsMicroorganismsBiological water/sewage treatmentNutritionBalance water
The invention discloses a biological preparation for balancing water quality for aquaculture. The biological preparation comprises the components of: sodium humate accounting for 49 percent, sodium thiosulfate accounting for 35 percent, biological flocculants accounting for 10 percent, bacillus subtilis accounting for 3 percent, streptococcus faecium accounting for 3 percent, wherein the bacillus subtilis is 3,000,000,000 / g and the streptococcus faecium is 3,000,000,000 / g. According to the biological preparation, the nutrition of a water body is balanced, the water quality is improved, the blue-green algae outburst is controlled, the growth of beneficial algae is activated, dissolved oxygen of the water body is increased, the content of beneficial microorganisms in the water body is increased, the occurrence of chronic nitrate and nitrous acid poison incidents of fishes can be prevented, the immune globulin and the antibody level of the fishes are improved, and the herd immunity of the fishes is improved; and by adding the streptococcus faecium, the true nutritive value of feed is improved, the concentration of ammoniacal nitrogen in excrements also can be reduced, and the pollution to the water quality is reduced.

Probiotic honey grapefruit tea and preparation method thereof
InactiveCN108887437AGuaranteed accumulationDoes not affect flavorTea substituesMethanosarcina barkeriStreptococcus fecalis
The invention provides a probiotic honey grapefruit tea and a preparation method thereof. In the technical scheme, lactobacillus casei and streptococcus faecium are taken as probiotic components and are blended with a conventional beverage, so that an intestinal tract probiotic effect is achieved. On such basis, the invention researches an approach for inhibiting growth of two probiotics, in orderto prevent the lactobacillus casei and streptococcus faecium from propagating in the beverage and influencing the flavor of the beverage. An experiment proves that an antagonism effect on propagationefficiency can be achieved when two probiotics are co-cultured with pyrococcus furiosus and methanosarcina barkeri; on such basis, an intergrowth environment and a nutritional condition of four microorganisms are researched; a treating method according to the invention can guarantee the biomass accumulation in early stage and can achieve the balance of flora scale of four microorganisms after mixed cultivation; the blending of the beverage and the mixed bacteria acquired according to the method is capable of keeping bacteria propagation basically stagnated under storage and transportation environments, so that the flavor of the beverage is prevented from being influenced.
