S ynthetic detergents constitute a large part of anthropogenic waste that is regularly discharged to the soil environment in Benin City. Literature is very scanty on the fate of the discharged effluent and the microflora of the soil receiving it. Adequate information on this matter could help in devising strategies for environmental protection and sustainability. This study focuses on the bacterial flora of Ariel and Omo synthetic detergents effluents. Laundry effluents from Unique, Superkleen and Mega laundries located in Benin City, were collected and analyzed by culturing it in Nutrient agar for the recovery of viable bacteria, the total viable cells count was determined following the pour plate method. Some physio-chemical parameters of the detergent effluent such as temperature, pH, BOD, COD, DO, total hydrocarbon and ionic components were determined following methods outlined by APHA. The detergent degrading potentials of bacterial isolates from the effluent were evaluated using the shake- flask biodegradation method. Bacteria belonging to the genera Pseudomonas, Escherichia, Bacillus, Klebsiella, Enterobacter and Citrobacter were isolated. The mean total heterotrophic bacterial counts of the laundry effluents were 8.4 x 10 5 cfu / ml, 2.2 x 10 5 cfu / ml, and 4.1 x 105 cfu / ml for Unique laundry, Superkleen laundry and Mega laundry respectively. The biodegradation of Ariel and Omo detergents by the indigenous bacterial isolates was optimal in the pH range of 5.0 � 7.4 with Pseudomonas showing the highest utilization potential and Citrobacter the least
Isaiah Nnanna Ibeh became a qualified Medical Laboratory Scientist in 1980 and thereafter obtained a Masters and PhD degrees in Immunology & Immunochemistry and Food & Industrial Microbiology respectively in 1988 and 1992 all from the University of Benin, Nigeria. He received a commonwealth Technical Scholarship to study in University of London 1986. He was awarded a Postdoctoral Research Fellowship by the Third World Academy of Science (TWAS), Italy, in 1995. He was a Postdoctoral Research Fellow of the Council of Scientific an Industrial Research (CSIR) of India (1995-1996). He has produced over 30 Masters of Science (M.Sc.) degree and 10 Doctor of Philosophy (Ph.D) degree holders. He worked for a year as a Medical Laboratory Scientist in the University of Benin Teaching Hospital before relocating to Microbiology Department of University of Benin where he worked as a Laboratory Technologist for 10 years. He was appointed Lecturer 1 in 1993 and rose through the ranks to a full Professor of Microbiology in 2003. His areas of interests are environmental toxins (mycotoxins), immunomodulation, food toxicology and ethnomedicine. He has over 100 scholarly publications in reputable local and international journals. He is a member of several Boards and Committees of University of Benin
