Indole degradation in a model system and in poultry manure was studied using an enrichment culture of two Acinetobacter species; Acinetobacter toweneri NTA1-2A and read more Acinetobacter guillouiae TAT1-6A.Degradation of indole was quantified using reverse phase high performance liquid chromatography (HPLC).The two strains were capable of degrading initial concentrations of indole ranging from 58.

58–300 mg/L.The degradation efficiency was 66.36% (NTA1-2A), 94.

87% (TAT1-6A), and 96.00% (mix) in 6 days when the initial concentration <300 mg/L.The strains were tested for enzymatic activity using 120 mg/L indole.

The enzyme extracts of NTA1-2A and TAT1-6A from culture medium degraded indole completely, and no appreciable change of indole concentration was witnessed in the control group.The NTA1-2A, TAT1-6A, and the mix of strains were also used for in vivo poultry manure fermentation and removed 78.67%, 83.

28%, and 83.70% of sawgrass virtuoso sg500 complete sublijet sublimation printer kit indole, respectively in 8 d.The strains showed a statistically significant difference (p < 0.

05) in indole removal efficiency compared with the control, but no significant difference between the two strains and the mix in indole removal capacity.We concluded that A.toweneri NTA1-2A and A.

guillouiae TAT1-6A are promising strains to remove indole and its derivatives to control the notorious odor in poultry and other livestock industries.
