Lignocellulosic biomass is a renewable, inexpensive and inedible carbon resource that can be used both as animal feed and as feedstock for production of biofuels/biochemicals. The biomass comprises mainly three structural polymers, namely cellulose, hemicelluloses and lignin. These polymers, collectively referred to as fibre, are highly interconnected in plant cell walls, forming a matrix resistant to enzymatic hydrolysis. My primary research interest is to harness the power of fibrolytic microorganisms to enhance utilization of lignocellulosic biomass in animal feeding and/or biorefineries. I do both basic and applied research to address this purpose. The methodologies I use include metagenomics, microbiology, laboratory-scale ensiling trials, etc. I have currently joint the group of professor Christina Divne at the KTH Royal Institute of Technology, Stockholm, Sweden to carry out biochemical/structural characterization of feruloyl esterase of Lactobacillus species. This class of enzyme has a great significance in improving utilization of lignocellulosic biomass.

Societal values of research
Production of food and energy in sustainable and environmentally friendly manners are some of the major concerns of our society. In this regard, lignocellulosic biomass is considered an important resource. However, the biomass has generally a low utilization efficiency. Currently, a number of energy intensive and/or unsustainable pre-treatments are used to improve biorefinery potential of lignocellulosic biomass. it appears that there is a need to evaluate pre-treatment strategies with lower environmental impacts. In addition, share of lignocellulosic biomass in animal feeding can significantly be improved. With my research, I aim to contribute to addressing these concerns.
My current four-year postdoctoral project, started from 2017, is financed by the Swedish Research Council Formas under the category of mobility grants for early-career researchers.
