Profile

Dr Akujobi is currently a reader in the Department of Microbiology, Federal University of Technology, Owerri. He has B.Sc in Microbiology (1994) from Abia State University Uturu, M.Sc in Industrial Microbiology (2002) from Federal University of Technology, Owerri and also a PhD in Environmental Microbiology (2008) from Abi State University Uturu. He has taught different branches of Microbiology since joining FUTO in 2002. He has supervised a lot of undergraduate and postgraduate theses.

In recent years, bacterial resistance to beta-lactam antibiotics has risen dramatically. Contributing to this increase has been the spread of extended-spectrum beta-lactamases (ESBLs), enzymes that hydrolyze the expanded-spectrum cephalosporins, like ceftazidime and cefotaxime, and/or the monobactam and aztreonam. Dr Akujobi’s research is geared towards isolation of bacterial species with the inherent capability to produce these enzymes and elucidation of the different classes of these. Efforts are made to use phytochemicals isolated from local plants to combat the antibiotic resistance in these organisms.

In recent time in Nigeria, there has been an increase in the menace of environmental pollution caused by oil exploration and transportation. This has caused tremendous hardship on the host communities of exploration oil companies and has led to constant friction between the members of these communities and the oil companies. There is a need to find an environmentally friendly approach to remedy this situation. Dr Akujobi’s work has been able to discover that the oil polluted soil can be remediated within a very short time by the use of pollutant-adapted microorganisms with the help of different types of organic nutrient supplements. Due to constant soil nutrient depletion, desert encroachment and indiscriminate environmental pollution in Nigeria, plants especially crop plants are always under environmental stresses which affect their yields. Dr Akujobi and his team are trying to identify some plant growth promoting rhizobacteria that would be able to ameliorate these stresses and improve plant yield. Moreover, Dr Akujobi and his research team have recently been engaged in bioenergy research to be able to find an environmentally friendly sustainable approach to generate electricity and biofuels. They were able to achieve a 12V generation in a microbial fuel using nine 1litre pig wastewater microbial fuel cell. The research team is currently working on upgrading the fuel cell to achieve a 100 KVA electricity generation. Efforts are also being made by the research team to power a 30 KVA generator with biogas obtained solely from organic wastes feedstock.
