Synergistic systems for biodegradations of lignocellulose in microorganisms: a review / 生物工程学报

ABSTRACT

Lignocellulose is the most abundant natural biomass. Bioconversion of lignocelluloses becomes a bottleneck for biorefinery, because of its complex structures and heterogeneous composition. Besides screening or engineering approach for single free enzymes with improved properties, an alternative approach is to study synergistic pattern with hydrolysis systems or mimic natural cellulosome for better performance in cellulolytic substrate degradation. Besides, bacterial co-cultures provide another synergistic cellulolytic system. Engineered strains with modified metabolic network could facilitate consolidated bioprocess by increasing yields as well as reducing costs.
