EVALUATION OF BIOLOGICAL ANTIMICROBIAL EFFECT OF ALOE VERA ON COLIFORM ISOLATES IN LEACHATE FROM A DUMPSITE

This study is to evaluate the biological disinfectant ability of Aloe vera (under different conditions and parameters) on coliform isolates from leachate that emanate a dumpsite.Leachate samplewas subjected presumptive test presence coliforms in them; positive samples were further confirmatory identify thermo-tolerant nature coliform. The Escherichia coli (FTE) Thermo-tolerant (non E. coli) (FTC) Disinfectant efficacies (with various condition evaluated isolated microorganisms samples, using disc diffusion method. showed concentration matters its efficacy with 5% storage showing high level zone inhibition microorganisms. Also was more effective at lower pH temperatures 0, 25 35oC.
