Aerobic Bacterial degraders in effluent from Itoku textile industry, Abeokuta

Abstract

The local textile industry in Itokun village is one major textile industry in Abeokuta Ogun state, known for “adire” production whose processes are not maintained at regulatory standards. This study involves isolating and identifying aerobic microorganisms in waste water effluents from this textile Industry and screening for aerobic degraders among the isolates. Fifty milliliter (50 ml) of three dye effluents; purple, brown and green were collected into sterile bottles and designated (Ef₁), (Ef₂) and (Ef₃). Tap water was used as control (Cont). Isolation, identification and screening of isolates for percentage decolorization were done using standard method. Colony forming units showed the trend Ef3 > Ef2> Ef1. Bacterial isolates included Bacillus megaterium, Staphylococcus simulans, Micrococcus varians, Bacillus niacinni, Lysinibacillus sp. and Bacillus carbonificus. Aneurinbacillus aneurinilytus alone was isolated from the control sample. Bacillus megaterium and Lysinibacillus sp. were the most predominant species in the effluents. S. simulans degradation was the most efficient and its use could be exploited.
