Strategies towards Reduction of Cellulases Consumption: Debottlenecking the Economics of Lignocellulosics Valorization Processes

Lignocellulosic residues have been receiving growing interest as a promising source of polysaccharides, which can be converted into variety compounds, ranging from biofuels to bioplastics. Most these replace equivalent products traditionally originated petroleum, hence representing an important environmental advantage. materials are theoretically unlimited, cheaper and may not compete with food crops. However, the conversion simpler sugars usually requires cellulolytic enzymes. Being still associated high cost production, cellulases commonly considered one main obstacles in economic valorization lignocellulosics. This work provides brief overview some most studied strategies that allow reduction consumption, improving economy lignocellulosics conversion. Cellulases recycling is initially discussed regarding processes recover active enzymes factors affect enzyme recyclability. Similarly, potential immobilization analyzed special focus on contributions elements process offer for prolonged times operation improved stability robustness. Finally, emergent concept consolidated bioprocessing (CBP) also described particular context consumption.
