June 2025: Professor Nyerhovwo John Tonukari – African Male Researcher of the Month

Academic and Professional Background

Born in the vibrant Urhobo community of Otorho Agbon in Ethiope East Local Government Area of Delta State, Nigeria, Professor Tonukari is the first son in a family of ten children. He exemplifies academic excellence and resilience. He received his early education in Sapele and later earned a First Class Honours degree in Biochemistry from the University of Maiduguri (transferred from Industrial Chemistry) and the University of Ibadan (U.I.), where he also completed his MSc in Biochemistry in 1990.

In 2000, he was awarded a Ph.D. in biochemistry from Michigan State University, East Lansing, USA—a major milestone in a career characterized by global learning and international collaborations. His professional training includes

• Protein Analysis at the University di Napoli, Italy (1992)

• DNA Sequencing at Washington University, St. Louis, USA (1994)

He is a recipient of the Rockefeller Foundation Fellowship (1994) and the Thoman Fellowship (1999–2000), highlighting his global recognition and excellence in scientific research.

Scientific Contributions and Research Focus

Professor Tonukari’s research spans a wide array of topics critical to sustainable agriculture, food biotechnology, and public health. His work showcases an exceptional understanding of both theoretical biochemistry and applied biotechnology.

1. Cassava Biotechnology and Microbial Enzymes

A major part of his research focuses on cassava fermentation and detoxification using fungi, particularly Aspergillus and Rhizopus species. His team has:

• Isolated microbial α-amylases with applications in food, paper, textile, detergent, and pharmaceutical industries

• Developed solid-state fermentation techniques to detoxify cassava and increase its protein content, enabling it to replace maize in broiler starter feed—a transformative step for Nigeria’s livestock industry

• Highlighted cassava’s potential as a glucose source in sugar, alcohol, and feed industries

2. Medicinal Plant Genomics and Bioactivity

His current work on Vernonia amygdalina (bitter leaf) involves:

• Characterizing genetic diversity through Rubisco gene sequencing

• Determining antioxidant and antigenotoxic properties using Allium cepa assays
  This cutting-edge work blends molecular biology with traditional medicine, contributing to the formal validation of indigenous healing practices.

Academic Leadership and Administrative Excellence

Professor Tonukari has held multiple strategic roles at Delta State University (DELSU), Abraka, including

• Dean, Faculty of Science (2020–2022)

• Head, Department of Biochemistry

• Acting Director, ICT (2010) and Pre-Degree Programme (2007–2010)

He has been pivotal in shaping curricula, improving research infrastructure, and mentoring young scientists.

Internationally, he worked as

• Fungal Molecular Biologist (Strain improvement), James R. Randle Research Center, Archer Daniels Midland Co., USA

• Associate Scientist, East Coast Fever Vaccine Project, International Livestock Research Institute (ILRI), Nairobi, Kenya

• Research Associate, Biotechnology Unit, International Institute of Tropical Agriculture (IITA), Ibadan

Publishing Pioneer and Advocate for Open Access

In 2002, Professor Tonukari founded Academic Journals, one of the earliest African-owned open-access publishing platforms, offering free and unrestricted access to scientific research. As the editor of the African Journal of Biotechnology, he has

• Championed open access to bridge the knowledge divide between developed and developing countries

• Assisted several African journals in adopting the open-access model, increasing global visibility and citations for African researchers

Entrepreneurship and Industry Impact

As chairman of Tonukari Biotechnology Company, he has developed products with agricultural and industrial applications, including

• Livestock feed derived from biotechnologically enhanced cassava

• Collaboration with the DELSU piggery for feed supply

• Local ownership and management of Sapele Times Newspaper, enhancing community engagement and youth development

Public Service and National Development

In recognition of his academic distinction and societal leadership, Professor Tonukari was appointed Honourable Commissioner for Higher Education, Delta State, by Governor Rt. Hon. Sheriff Oborevwori. In this role, he continues to

• Reform tertiary education to meet global standards

• Enhance STEM education and research productivity

• Support technology-driven learning and quality assurance in academic institutions

Affiliations and Recognition
