Preparation method of composite EM flora for aquaculture decontamination

The invention discloses a preparation method of a composite EM flora for aquaculture decontamination. The composite EM flora comprises lactobacillus acidophilus, bacillus subtilis and candida oviposition. According to the invention, through screening, culturing and optimizing local dominant strains, including spores, yeast, lactobacillus, photosynthetic bacteria and other strains having the pollution reducing effect on aquaculture water, and through carrier compounding, the active activity of the strains is ensured, and the synergistic effect of the strains is exerted at the same time. The various water body toxins can be effectively degraded, macromolecular organic matters are decomposed, and toxic and harmful pollution sources are degraded, so that the breeding of harmful bacteria is inhibited, and various water body harmful indexes are reduced. 本发明公开了一种用于水产养殖除污的复合EM菌群制备方法：复合EM菌群中包括嗜酸乳杆菌、枯草芽孢杆菌、产卵假丝酵母。本发明通过筛选、培养、优化本土优势菌种，包括于芽孢、酵母、乳杆菌、光合菌等在内的对养殖水体有降污效果的菌种，通过载体复配，确保各菌种的活性活力，同时发挥其协同作用。能有效降解各种水体毒素、分解大分子有机物、降级有毒
