Summary: Stochastic models have the potential to be important tools in describing the complex network of reactions involved in enzymatic hydrolysis of polysaccharides, but many current models lack biologically meaningful parameters. Only a few models utilize classical enzyme kinetics parameters, and recent research on stochastic models for cellulose hydrolysis provides valuable insights into the molecular-level phenomenon limiting hydrolysis rates. Further improvements are necessary for stochastic models of enzymatic polysaccharide hydrolysis to become widely used tools for guiding process development.

Summary: Conversion of lignocellulose to sugar relies on costly cellulase and xylanase, therefore, improving enzyme utilization is crucial. Enzymatic kinetics can guide researchers to efficient enzyme utilization, with models based on second-order reactions being superior to first-order ones. Enzyme activity and sugar yield have a linear relationship, while higher enzyme loading leads to reduced activity retention.

Summary: Increase in mixing intensity is not essential for efficient cellulose hydrolysis at higher solid loadings; a lower mixing intensity is actually needed for higher cellulose conversion. Mixing at the initial stage is crucial, while continuous mixing throughout the hydrolysis process is not necessary for improved efficiency.

Summary: Hydrolyzing lignocellulose and transforming it into chemicals and fuels is an essential aspect of biorefining. Previously, lignin was believed to inhibit the enzymatic hydrolysis of lignocellulosic substrates. However, recent research has shown that under specific conditions, lignin can actually increase the sugar yield and act as an activator/promoter of enzymatic hydrolysis. Furthermore, lignin-based carriers have been developed to reduce the load and cost of cellulases.

Summary: This paper used five different types of biosurfactants to enhance the saccharification efficiency in the enzymatic hydrolysis process. The addition of sophorolipid increased the enzymatic hydrolysis efficiency by 30.65%, while the combination of sophorolipid and tea saponin further increased the efficiency to 99.56%. These biosurfactants acted synergistically to inhibit enzymatic inactivation and non-productive adsorption of lignin. This study proposes an effective method to improve enzymatic hydrolysis efficiency and reduce enzyme dosage by utilizing biosurfactants.

Summary: Ammonia inhibition commonly occurs during anaerobic digestion of N-rich organic waste. This study investigated the effects of ammonia on microbial electron transfer activity and energy generation pathways. The results showed that high concentrations of ammonia led to a reduction in methane production and decreased efficiency in biogas generation. The microbial community composition and metabolic activities were also affected, resulting in decreased methane production efficiency. The supplementation of electrons via electro-fermentation emerged as a potential approach to mitigate ammonia inhibition and enhance process efficiency.

Summary: This study investigated the effects of enzyme loading, alcohol/acid ratio, and temperature on the yield of methyl levulinate through a kinetic model. The results showed that enzyme loading increases the rate constants of esterification/hydrolysis, while temperature elevation increases both the rate constants and the equilibrium constant. The application of binary regression analysis was successful in studying the enzymatic esterification kinetics.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
