The invention discloses a composite microbial deodorizer and a preparation method thereof. According to the invention,
thiobacillus ferrooxidans,
rhizobium sludge,
bacillus amyloliquefaciens,
rhodopseudomonas palustris,
pseudomonas stutzeri,
bacillus coagulans and
hansenula polymorpha are selected for use; liquid
fermentation is performed respectively, and then compounding is performed in proportion; then
linalool is added in proportion and the substances are fully mixed to prepare a composite microbial deodorizer capable of effectively expelling flies and insects, inhibiting growth and propagation of harmful
flora and reducing and removing foul gas in the environment. The
thiobacillus ferrooxidans (CFU / g) in the product is greater than or equal to 2.95*10<8>; the
rhizobium sludge (CFU / g)is greater than or equal to 1.05*10<8>; the
bacillus amyloliquefaciens (CFU / g) is greater than or equal to 1.73*10<8>; the
rhodopseudomonas palustris (CFU / g) is larger than or equal to 2.55*10<8>; thepseudomonas stutzeri (CFU / g) is larger than or equal to 1.15*10<8>; the
bacillus coagulans (CFU / g) is larger than or equal to 2.86*10<8>; the
hansenula anomala (CFU / g) is larger than or equal to 2.97*10<8>; and the total amount of organic acids is larger than or equal to 25.8 g / L. The product provided by the invention has an obvious deodorization effect, the NH3 removal rate is greater than or equal to 78.14%, the H2S removal rate is greater than or equal to 71.64%, the
odor concentration
elimination rate is greater than or equal to 84.95%, and the mosquito and fly expelling rate is greater than or equal to 74.16%.
