Abstract

Recent years have seen a tremendous demand in bioenergy. The technological advancements in the production of second-generation biofuels have opened a plethora of opportunities for the valorization of natural polymers. Lignin is one of the most abundant and recalcitrant materials available on earth. Advancements in genetic engineering, metabolic engineering and synthetic biology applications fueled tremendous interest in the valorization of lignin into fuels as well as platform and commodity chemicals. Though there is a growing continuum for biofuel advancements in recent years, at the same time, a rising upsurge has also been envisaged in the valorization of waste bioresources. Therefore, this chapter entails about various aspects and embodiments related to lignin bioconversion and their routes for obtaining various products. This chapter also highlights current biotechnological interventions for the improvement of the valorization process as well as the current challenges and future perspectives in this burgeoning area.

Keywords: Genetically encoded biosensors, Lignin valorization, Microbial fermentation, Metabolic engineering, Metagenomics, Synthetic biology, Value-added products.
