Dr. Grace N Ijoma is a senior lecturer of Biotechnology at the Pearson Institute of Higher Education and a postdoctoral fellow at the University of South Africa. Her PhD focused on antagonistic interspecific interactions amongst fungi. Previous paper presentation of portions of this work was presented at 8th International Conference on Environmental Science and Technology. Houston Texas, USA in 2016 and was judged first place paper. She is eclectic in her research interests and has a keen interest in several areas including Bioprospecting of niche environments, Food Microbiology, Environmental and Industrial Microbiology and Biotechnology (particularly Fermentation technology and process optimization), Microbial enzymes and biodegradation of xenobiotic compounds including polyaromatic hydrocarbons, pesticides and synthetic dyes, Ground water quality research and Microbial treatment of industrial waste water, Solid waste management. She is currently supervising undergraduate and post graduate research projects designed towards industrially relevant applications


There is a renewed interest in finding sustainable energy sources with particular focus on agricultural waste residues. The justification for this perspective is that this eliminates the need to cultivate already scarce land mass and has the added advantage of utilizing agricultural residues that otherwise would have presented problems of waste management. However, the use of agricultural waste residue is significantly hindered by the difficulty in degradation of lignocellulose components of its structure. Ligninolytic fungi have the ability to degrade these agricultural waste residues but enzymes employed in the degradation process are produced in limited quantities and more often during the secondary metabolism by these organisms. Methodology & Theoretical Orientation: The objective of this study was to investigate a strategy that could improve the production of these enzymes and likely accelerate the organisms into secondary phase enzyme production mode. Dual culture combinations of 10 fungi that had previously demonstrated the ability to produce ligninolytic enzymes were cultivated on PDA to ascertain their interspecific interaction and also on three agricultural residues, corn cob, sugarcane bagasse and wheat straw. Spectrophotometric analysis of the enzyme activities of laccase (Lacc), manganese peroxidase (MnP) and lignin peroxidase (LiP) demonstrated that observed antagonistic invasions yielded an increased enzyme activity in dual cultures on all the substrates. Findings: The highest ligninolytic enzyme production was observed in invasion/replacement interactions that involved Trichoderma sp. KN10 with average mean value in MnP production was approximately 1.46 U/ml compared to all monocultures of 0.055 U/ml. Similarly, Lacc mean value was 0.10 U/ml compared to monocultures value of 0.05 U/ml. This study demonstrated and proved that antagonistic invasion by some fungi in co-culture, although dependent on substrate affinity, can increase production of one or more of the three enzymes laccase, lignin peroxidase and manganese peroxidase.

Muhammad Usman former Director General of Agricultural Research System, Government of Pakistan who retired from service after a spotless career of about 35 years with senior level experience on research and development of integrated agricultural production, industries, food and beverage, bioenergy on a sustainable way. He is basically an agricultural scientist with specialization of agricultural, food and biochemistry working on the yield and quality of various products and published several research papers. He is considered as the senior most scientist in the world, always participated in the international conferences as a keynote speech, renowned speaker, organizing committee member as well as moderator of the conferences around the world. He established Prominent Agro Based Industries, Agro Based Industries and Consultancy SDN BHD in Malaysia and Foundation for Rural Development in Pakistan with primary aim to work on integrated agricultural project for rural development through improvement in agriculture and consultancy services to the farmers at Malaysia.


The role of bioenergy on the poverty alleviation in the developing countries of the world like South Asia were studied and reported that bioenergy can be produced from plant, plant derived materials, renewable in nature, derived from biomass and used directly for heating known as biomass fuels. Biomass can also be used directly for heating or power known as biomass fuel. Biomass is a biological material derived from living organism including plants and animals, known as agricultural biomass. As per report in Pakistan, a single cow is sufficient to provide a whole family with their milk and energy needs as biogas generated from the dung of cow. This is not only the cheapest source of energy but also an important alternative to replace the costly item like furnace oil, coal, natural gas used for non-renewable energy. It means, bioenergy is the basic need of our life, main source of poverty and without energy life is almost impossible. In view of the importance of bioenergy, the developing counties are still facing energy crises due to dense population and highly dependent on non-renewable energy. Although, a great potential of bioenergy is available. As reported, due to lack of energy nearly one billion people go to bed hungry each night. Keeping in view the importance of bioenergy, it is necessary that the potential of bioenergy may be commercialized to increase the income, reduce the energy crises as well as poverty in the developing countries of the world. It is concluded that bioenergy is the powerful tool on the poverty reduction and hunger in the world.

Bor-Yann Chen has expertise in biomass energy and bioremediation for biotechnology. His serial studies focused on applications in wastewater decolorization, bioremediation engineering, environmental toxicology and biofuel cells. He has completed PhD from University of California, Irvine in 1995 and used to be NRC awarded Research Associate to work in NRMRL/US EPA, Cincinnati Ohio. He is a distinguished Professor in Department of Chemical and Materials Engineering, National I-Lan University, Taiwan. He has published 150+ SCI-peer reviewed articles in reputed journals and has many national awards (e.g., Professor Yen-Ping Shih Best Paper Awards of 2007, 2011, 2013 and 2016 from Taiwan Institute of Chemical Engineers). Recently his findings also deciphered chemical structures of electron shuttles and recalcitrant dyes which are crucial to simultaneous pollutant biodegradation and biomaterial/bioenergy recycling for sustainable green technology. Considering environmental friendliness, this study explored natural bioresources (e.g., medicinal herbs and edible flora) for bioenergy and high-value production generation. He provided different alternatives to re-evaluate indigenous biomaterials with electrochemical potentials for bioenergy extraction, biorefinery development and derived applications.



This serial study revealed the optimal strategy to supplement extracts of polyphenolics abundant medicinal herbs and Camellia tea as electron shuttles (ESs) for stimulating bioenergy generation in microbial fuel cells (MFCs). Apparently, Camellia sinensis (L.) Kuntze and Syzygium aromaticum were promising electroactive ESs. Moderate temperature (ca. 65°C) and slightly alkaline pHs (~10) were electrochemically feasible conditions for herbal extraction. Optimal contents of polyphenolics rich herbs and tea extracts with maximal electrochemical activities could be stably obtained. Power density of MFC supplemented with Camellia green tea extract could significantly increase ca. 176%, suggesting that unfermented green tea extract would be the most appropriate ESs. As correlation analysis indicated that total phenolic contents and electron shuttling capabilities were all electrochemically associated. In addition, chemical structure is strongly affected whether antioxidant activities of polyphenolics abundant herbal extracts could be reversibly switched to be electron shuttling capabilities (e.g., substitution patterns). Dihydroxyl substiutuents of ortho or para to each other were very likely promising for electron-shuttling, but not for meta substituents. Moreover, bioelectrochemical treatment upon medicinal herbal extracts (e.g., cyclic electron donating and withdrawing processes) might provide an electroactive alternative to attenuate herbal biotoxicity to fully express bioenergy-shuttling activities in applications (e.g., bioenergy extraction and herbal medication).
