Efficient hydrolysis of cellulose in agricultural waste (e.g., coconut fiber) is critical for biorefining processes such as second-generation bioethanol (2G ethanol) production. However, free cellulases suffer from low thermal stability and challenges recovery. To address this, we developed cross-linked enzyme aggregates (CLEAs) combined with magnetic nanoparticles (magnetic CLEAs, m-CLEAs) to enhance reusability. In this context, solutions ethanol, acetone, ammonium sulfate were used...
Enzyme immobilization is a useful tool to produce biocatalysts with improved performance, such as high activity, stability at operational conditions, and easy recovery reuse. In this context, the production of second-generation ethanol using immobilized enzymes was reviewed. Emphasis placed on pre-treatment and/or hydrolysis steps increase efficiency reduce cost process. addition, process design bioethanol critically enzymatic pre-treatment, laccases, manganese peroxidases, lignin lytic...
<title>Abstract</title> This study investigates the production and application of xylanases derived from fungus Penicillium sp. FSDE15, obtained via solid-state fermentation (SSF). Wheat bran served as substrate, either in its pure form or mixed with sisal fiber. underwent incubation SSF for 168 h, daily sampling to evaluate xylanase activity. Xylanase analyses were conducted under various temperature pH conditions optimize enzymatic activity, optimal determined 50°C 4.8. SDS-PAGE...
