The Official Journal of the Mycological Society of Nigeria ( MYCOSON)

Welcome to Nigerian Journal of Mycology


Late Professor Benjamin Afolabi Oso was a widely travelled academician and a scientist of international repute. After obtaining his Bachelor of Science (Honours) degree in Botany with Second Class Upper from the University of Ibadan in 1965, he proceeded to Birkbeck College University of London, where he bagged his Ph.D degree in Botany(Mycology) in two and a half years in June 1968 (i.e. December 1965 - June 1968).

Prof Oso joined University of Ibadan as Lecturer II in the Department of Botany in June 1968 and was promoted Lecturer I in October 1972, Senior Lecturer in October 1974 and Professor in October, 1978. He was Head of the Department of Botany and Microbiology, University of Ibadan for two terms – (1983-1987 and 1992-1995), a member of the University Senate, member of Appointments and Promotions Committee, University of Ibadan from 1980-1982. Professor Oso is currently the Director of Research at Afe Babalola University, Ado-Ekiti, since 2010, having retired as Professor of Microbiology from the University of Ibadan in 2005 after thirty-seven (37) years of meritorious service. He is a currently member of the Management and the Governing Council as well as the Director of the Students Industrial Work Experience Scheme (SIWES) at Afe Babalola University Ado-Ekiti (ABUAD).

He was a Nigerian Federal Government success Scholarship Award winner for postgraduate studies (Ph.D.) at Birkbeck College, University of London (1965- 1968), a Ford Foundation Visiting Scholar Award at the University of Califonia, Berkeley (1973), an Alexander von Humboldt Foundation Visiting Scholar Award at the Justus Liebig University, Giessen, Germany (1980-1983).

Within and outside Nigeria, Professor Oso has served as Visiting Professor, External Examiner and assessor of the publications of candidates being considered for Readership and Professorial positions in a number of Universities. He was a member of the Governing Council of the University of Abuja from May 2000-May 2004. A member of various learned societies, he has authored many publications in scientific journals of international repute in Botany and Microbiology and a Laboratory Manual of Microbiology.

Some of the notable achievements of Professor Oso are as follow:

• He was the first scientist to identify the celebrated water hyacinth (Eichhornia crassipes) when the weed first invaded the Nigerian waters in Lagos in January 1985 and was appointed the Nigerian National Research Coordinator of the Water Hyacinth Project by the Federal Ministry of Science and Technology in 1986.

• Through intensive research he has produced from aquatic weeds a powdery material which he has heavily impregnated with special isolates of non-pathogenic microorganisms for fast biodegradation of organic matter. This substance, which he has patented as OBD-plus (i.e. Oso Biodegrader-Plus) is an excellent agent for pollution control and environmental management as it breaks down solid wastes (garbage) into nutrient-rich organic fertilizer within 4 weeks, removes odour and purifies sewage and industrial effluents into clean water and bio-remediates oil polluted environments, land and water as well as heavy metal contaminated soils. This is currently being used in a number of places in the country.

• He was awarded a certificate of Honour in November 1995 by the Delta State Chapter of the University of Ibadan Alumni Association for providing practical solutions to some of Nigerian pressing environmental problems.

• He was member of the National Committee on the Environmental Cleanup and Remediation of Oil Impacted Areas of the Niger Delta.

• He was the winner of the International Institute for Training, Research and Economic Development (IITRED) 2012 Research Prize for Technological Innovation in Oil & Gas.

• He was awarded the Fellowship of International Institute for Training, Research and Economic Development (IITRED) on 26th November, 2015.

• He was a recipient of an Award of honour and Life-Time Achievements from the Nigerian Society for Microbiology (South West Zone) in recognition of his immerse contributions to the field of Microbiology on 6th December, 2016.

• He has been serving meritoriously as the National President of Mycological Society of Nigeria (MYCOSON) since the inauguration of the Society in 2006 till October 2018.

• Sequel to his immense contributions to the development of Mycology in Nigeria, Professor Oso was installed as Fellow of Mycological Society of Nigeria (FMYCOSON) in 2017.

• He was a justice of the Peace of Oyo State of Nigeria.

• He was the Grand patron of the Nigerian Association of Microbiology Students.

• He has donated a trophy to the Association for Annual Inter-University Competition on topics of microbiological interest, and in addition awards prizes to winners.

In addition to the vast number of undergraduates and M.Sc. students he has taught and whose projects he has supervised in the University, many of whom are now professors and highly placed personalities holding very important positions in the country, including Vice-Chancellors, Deputy Vice-Chancellors, Deans of Faculties, Governors, Senators, Directors etc, Prof Oso has successfully designed and supervised the research projects of twenty-four (24) Ph.D. students, seventeen (17) of whom are now Professors. Remarkably, Professor Oso remained a dedicated, consummate, articulate and visionary servant leader and pragmatic administrator, always radiating and showing love and concern about the best form of service delivery, to his subordinates and any assignment he had undertaken over the decades of active involvement in University administration.


With a heavy heart, and as a rude shock, we received the news of the demise of my dear academic father, teacher and mentor, Professor Benjamin Afolabi Oso on Saturday 16th March, 2019. Baba Oso, during his life-time was an exceptional Biologist, a teacher per excellence, a leader of leaders, a team player and a caring father who was always there for everyone that came across him. Baba Oso co-founded the Mycological Society of Nigeria (MYCOSON) with late Prof R. O. Alabi, and then served meritoriously as the pioneer National President of the society from May 2006 to October 2018. He was also the pioneer chairman of Board of Trustees (BOT) of MYCOSON until his death. We will surely miss Baba Oso, knowing what he stood for in terms of commitment, dedication, forthrightness, faithfulness, selflessness and steadfastness in his service to God and humanity, most especially his love for the children. While commiserating with the family, we join others in praying for the repose of his soul and fortitude for the entire Oso family to bear this monumental loss.
