Abstract
The valorization of lignin, a currently underutilized component of lignocellulosic biomass, has attracted attention to promote a stable and circular bioeconomy. Successful approaches including thermochemical, biological, and catalytic lignin depolymerization have been demonstrated, enabling opportunities for lignino-refineries and lignocellulosic biorefineries. Although significant progress in lignin valorization has been made, this review describes unexplored opportunities in chemical and biological routes for lignin depolymerization and thereby contributes to economically and environmentally sustainable lignin-utilizing biorefineries. This review also highlights the integration of chemical and biological lignin depolymerization and identifies research gaps while also recommending future directions for scaling processes to establish a lignino-chemical industry.

Koh HG, Yook S, Oh H, Rao CV, Jin YS. Toward rapid and efficient utilization of nonconventional substrates by nonconventional yeast strains. Curr Opin Biotechnol 2024; 85:103059. [PMID: 38171048 DOI: 10.1016/j.copbio.2023.103059] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 12/05/2023] [Accepted: 12/06/2023] [Indexed: 01/05/2024]
Abstract
Economic and sustainable production of biofuels and chemicals necessitates utilizing abundant and inexpensive lignocellulosic biomass. Yet, Saccharomyces cerevisiae, a workhorse strain for industrial biotechnology based on starch and sugarcane-derived sugars, is not suitable for lignocellulosic bioconversion due to a lack of pentose metabolic pathways and severe inhibition by toxic inhibitors in cellulosic hydrolysates. This review underscores the potential of nonconventional yeast strains, specifically Yarrowia lipolytica and Rhodotorula toruloides, for converting underutilized carbon sources, such as xylose and acetate, into high-value products. Multi-omics studies with nonconventional yeast have elucidated the structure and regulation of metabolic pathways for efficient and rapid utilization of xylose and acetate. The review delves into the advantages of using xylose and acetate for producing biofuels and chemicals. Collectively, value-added biotransformation of nonconventional substrates by nonconventional yeast strains is a promising strategy to improve both economics and sustainability of bioproduction.
