Screening of skatole-degrading bacteria and control of human fecal odor by compound bacteria

Abstract Purpose The biodegradation of skatole was used as a starting point in this study, and existing strains degrading NH 3 H 2 S the laboratory were combined to create composite deodorant. deodorization effect deodorant on human feces investigated order provide foundation for fecal odor gas treatment. Methods Skatole-degrading bacteria identified, degradation conditions optimized, metabolites identified using liquid chromatography-mass spectrometry (LC-MS). skatole-degrading with make compound deodorizer, deodorizing deodorizer fresh old compared. Liquid chromatography, specific sensors, chromatography determine contents skatole, , S, volatile organic compounds, microbial diversity examined. Results Microbial agents Y capable utilizing screened out under aerobic facultative anaerobic conditions, respectively. Within 48 h, rate by agent 88.52%. Following condition optimization, optimum temperature 33 °C, pH 7. main functional Acinetobacter xiamenensis . determined (LC–MS), six possible found, including 3-aldehyde indole, 3-carboxyl 1H-indole-2,3-dione, 3-methyl indole pyruvate. Lactobacillus rhamnosus Saccharomyces cerevisiae then proportion form 5-day manure group 88.11%, while 47.56%. Conclusions developed study has solid effect, particularly control obsolete feces. use can efficiently degrade feces, providing theoretical remediation actual world. Graphical
