Summary: This study employed lignin blockers, including non-catalytic protein and surfactants, to enhance the enzymatic digestibility of pretreated poplars. Among them, Tween 80 showed the most significant improvement, increasing glucose yield and reducing the required enzyme loading. Quartz crystal microbalance analysis revealed that Tween 80 had a higher binding rate on lignin surfaces compared to enzymes and significantly reduced the enzyme-lignin binding capacity and rate. These findings contribute to understanding the mechanism of surfactant promotion in enzymatic hydrolysis.

Summary: This review article discusses the development and use of manganese oxide modified biochar (MnOBC) for the removal of organic and inorganic pollutants from water. The preparation and characterization of MnOBC, as well as its capacity for pollutant removal, are explored in relation to various factors. The review also examines the mechanisms of pollutant removal by MnOBC and the fate of sorbed pollutants. The impregnation of biochar with MnOx enhances its sorption capacity, making it an effective biosorbent for remediation of contaminated water environments.

Summary: This study aimed to produce low-cost activated carbon (AC) from corn stigmata (CS) through chemical activation at low temperatures using H3PO4, ZnCl2, and KOH. The results showed that activation with phosphoric acid resulted in an adsorbent with a larger specific surface area and high pore size. Increasing the activation temperature from 200 to 500 degrees C led to the development of surface functions, a mixture of meso and microporosity, and a significant increase in specific surface area. The physicochemical and textural properties of ACs were analyzed using various techniques, and the adsorption process of methylene blue (MB) was well described by mathematical models. The maximum adsorption capacity for MB was found to be high compared to previous literature.
