The invention discloses a microbial fertilizer with growth-promoting and yield-increasing effects and a preparation method thereof. The microbial fertilizer is prepared by mixing a hydrogel fertilizer and a microbial agent, the hydrogel fertilizer is formed by taking chitosan as a base material and carrying out cross-linking reaction with 2, 2-dimethyl-5-hexenoic acid, N-(N-butoxymethyl) acrylamide and urea, and the microbial agent is prepared by loading bacteria N9 separated from farmland soil on biochar. The microbial fertilizer has good water retention performance and nutrient slow release effect, the contained microorganisms can effectively promote growth, tests show that the soil water retention rate can be remarkably increased, growth of pakchoi and other crops is promoted, the biological safety is high, and the microbial fertilizer is suitable for achieving crop growth promotion and yield increase in agricultural production.

The present invention relates to bacterial probiotics useful in aquaculture. Specifically, it discloses a selection of non-hemolytic, proteolytic, stress-tolerant bacterial strains with enhanced quorum- quenching capabilities. Moreover, the method allows detection of novel species of bacteria whose probiotic attributes could be massive for aquaculture. From the isolated bacteria, selected species were tested for their probiotic efficacy in Nile tilapia (Oreochromis niloticus), a key fish species in global finfish aquaculture. The species demonstrated significant efficacy in improving the health and growth performance of Nile tilapia juveniles. Specific growth rates and weight gain, and improved feed conversion ratios without adverse effects on fish health were observed. The gut microbiome was positively influenced by promoting beneficial bacteria while reducing harmful (opportunistic) species, leading to improved immune modulation. Survival rates were significantly boosted during a pathogenic challenge, and key immune genes were upregulated, indicating stronger local immune defenses. These findings show that the selected probiotic species offer substantial benefits for growth, feed efficiency, and disease resistance, emphasizing their potential for widespread application as probiotics in aquaculture.
