The invention belongs to the technical field of environmental
biology, and particularly relates to a key
gene for degrading
skatole by
enterococcus haiseri ID05 and application of the key
gene for degrading
skatole by
enterococcus haiseri ID05, and the test process of the key
gene for degrading
skatole by
enterococcus haiseri ID05 is as follows: selecting an enterococcus haiseri IDO5 strain, an LB culture medium, an inorganic salt culture medium and
reagent consumables and instruments required in the test process; the degradation rate of the enterococcus haiseri IDO5 on 100 mg / L of skatole in an inorganic salt culture medium reaches 67.01 + / -0.01%, and it is shown that the enterococcus haiseri IDO5 has the good degradation capacity on the skatole. Besides, the degradation rate of the IDO5 on skatole in sterilized pig
manure wastewater reaches up to 96.10%, the degradation rate of the IDO5 on skatole in unsterilized pig
manure wastewater is also 78.17%, and the enterococcus hirsuti IDO5 has good degradation capacity on skatole in pig
manure wastewater and has good application potential in pig manure wastewater, so that when the pig manure wastewater is discharged, the enterococcus hirsuti IDO5 can be used for degrading the skatole in the pig manure wastewater. After being treated by enterococcus hirsuti IDO5, the wastewater can be discharged, so that the
pollution to the environment is effectively reduced.
