The defined research program focuses on production of bio-based products, such as enzymes, biochemicals, and biofuels from agro-industrial residues and dedicated biomass crops. Several areas make up the program to address the diversity of renewable resources available and various processing methods that can be applied to generate products and enhance value: --Semi-solid fermentation technology, including solid substrate cultivation and liquid cultivations using solid carbon sources --Enzymatic conversion methods and fermentation for development of effective biomass conversion processes --Hybrid application of thermal and microbial conversion technologies for biofuel production from lignocellulosic biomass --Solvent extraction processes are also being investigated for biomass materials that contain natural colorants, nutraceuticals and other high value compounds. Integrated processing systems, linking crop production and storage practices to development of conversion technology, analytical methods and process model evaluation The projects and activities in these areas have evolved over time, yet the primary goal of establishing functional uses of renewable materials suited to NC for industrial bioproducts that promote sustainability and enhance rural development has remained the same. The biomass studied includes sugar, starch and lignocellulosic crops with divisions of the program developing strongly around sweet sorghum, industrial sweetpotatoes (ISP), perennial grasses, oil seeds, and single carbon gases derived from lignocellulosic materials. The research approach involves both basic and applied objectives, leading to development of processes at various scales, lab to industrial, that often integrate multiple operations within a given system. The program incorporates research direction for and scholarly contributions from research associates, post-docs, graduate students and undergraduate researchers. Education and outreach activities to disseminate advances in the research are also efforts integrated into the program.
