The development of Sorghum bran based bio-refinery process
Oyenike Makanjuola and Chenyu Du
University of Huddersfield, UK
The project aims to develop a sorghum waste biomass-based bio-refinery process to convert sorghum bran into value-added
products. Sorghum bran is a food waste rich in starch and cellulose, making it a suitable substrate for bio-refinery process
development. Solid state and submerge fungal fermentations were carried out first to culture A. awamori for the production
of glucoamylase and alpha-amylase. Then the enzyme solutions were used for the enzymatic hydrolysis of sorghum bran
for the production of a glucose-rich fermentation medium. The impact of pH, temperature, yeast extract, mineral content
and inoculation ratio on enzyme activities were investigated in both solid-state fermentation and submerged fermentation.
Response Surface Methodology (RSM) was used to further optimize the glucoamylase activity. The hydrolysis efficiency of
sorghum bran using the enzyme solution was evaluated and sorghum bran hydrolysate was used as the substrate for the
production of bio-ethanol and itaconic acid, demonstrating the feasibility of converting a sorghum waste biomass to value-
added products via a sustainable and environmentally friendly process.
Biography
Oyenike Makanjuola obtained her from Bowen University, Nigeria in 2011 and obtained her at the University of Huddersfield in 2014 with a Distinction.
As a result, she was awarded the Vice-chancellor Scholarship for her Ph.D. programme at the University of Huddersfield. Oyenike is currently a 3rd year Ph.D.
student in the School of Applied Sciences, the University Of Huddersfield. Her research area focuses on the conversion of sorghum waste biomass and wheat
straw into value-added products.
