specific Embodiment approach 1
[0033] Specific embodiment 1: In this embodiment, the compound microbial agent for degrading indole is prepared from three strains of indole-degrading microorganisms: Pseudomonas monteilii QM (pseudomonas monteilii QM), Bacillus L1 and Tolumonas G1 , the specific preparation method is as follows:
[0034] 1. Inoculate Pseudomonas monteilii QM (pseudomonas monteilii QM), Bacillus L1 and Tolumonas G1 on liquid medium for activation respectively;
[0035] 2. Pick three activated single colonies and inoculate them on the liquid medium respectively, and enrich them for 1-3 days under aerobic conditions with a temperature of 20°C and a shaking speed of 150r / min;
[0036] 3. Inoculate the three kinds of single bacteria after the enrichment culture into the liquid medium respectively, and cultivate until the number of bacteria is 10 9 ~10 10 Each / mL, and then Pseudomonas monteilii QM (pseudomonas monteilii QM), Bacillus L1 and Tolumonas G1 were mixed at a volume ratio of 1:2:1 to ob...
