A sequential pretreatment method for hydrolyzing rigid hemicelluloses and cellulose content in the bamboo biomass was investigated in this study. The effects of different parameters, such as nature of biomass, type of acid, acid and biomass concentration, were studied. Under the optimum condition of 5% (v/v) HCl-treated biomass and biomass concentration (8%, w/v), the maximum yield of sugar (619 mg/g of biomass) was obtained. The enzymatic hydrolysis parameter conditions were further optimized by response surface methodology-based central composite method. According to the results, the highest yield of sugar (515 mg/g of biomass) was obtained at hydrolysis temperature 50 °C, biomass concentration 8.9%, w/v, enzyme concentration (199.8 mg/g of biomass) and time 60 h, respectively. The effects of untreated, pretreated and enzymatically hydrolyzed biomass structure and complexity were investigated by field emission scanning electron microscopy and X-ray diffraction techniques.

ConspectusFor chemical reactions with complex pathways, it is extremely difficult to adjust the catalytic performance. The previous strategies on this issue mainly focused on modifying the fine structures of the catalysts, including optimization of the geometric/electronic structure of the metal nanoparticles (NPs), regulation of the chemical composition/morphology of the supports, and/or adjustment of the metal-support interactions to modulate the reaction kinetics on the catalyst surface. Although significant advances have been achieved, the catalytic performance is still unsatisfactory.

Substantial amounts of oily wastewater are inevitably generated during petroleum extraction and petrochemical production, and the effective treatment of these O/W emulsions is crucial for environmental protection and resource recovery. The development of an environmentally friendly, cost-effective, and efficient demulsifier that operates effectively at low concentrations remains a significant challenge. This study introduces an eco-friendly ionic liquid demulsifier, Cotton Cellulose-Dodecylamine (CCDA), which demonstrates exceptional demulsification performance at low concentrations.

This study investigates the production of polyhydroxybutyrate (PHB) using the thermophilic bacterium Caldimonas thermodepolymerans in fed-batch fermentation. This research highlights the potential of thermophilic bacteria in biopolymer production due to their ability to operate at high temperatures, which reduces contamination risks and enhances energy efficiency. Optimal fermentation conditions were identified at a temperature of 50 °C, with the strain achieving a maximum specific growth rate (μ) of 0.

Boron (B) is essential for plant growth and helps mitigate metal toxicity in various crop plants. However, the potential role and underlying mechanisms of B in alleviating antimony (Sb) toxicity in rice remain unexplored. In this study, we investigated the effects of H₃BO₃ supplementation (30, 50, and 75 μM) on morphological growth, physiological and biochemical traits, Sb content, and the subcellular distribution of Sb in rice plants under 100 μM Sb stress during the seedling stage in a hydroponic system.
