Summary: This study identified a potential lignocellulolytic enzyme producer, Penicillium rubens, which overexpressed two genes (PrFaeA and PrFaeB) with feruloyl esterase (FAE) activity. Enzyme extracts from PrFaeB-enriched cultures showed optimal FAE activity at pH 5.0 and 50-55 degrees C, as confirmed by proteome analysis and mass spectrometry. The study also analyzed other lignocellulolytic activities, untargeted metabolites, and scaled up FAE production in stirred tank reactors. These findings highlight the potential of P. rubens as a promising lignocellulolytic enzyme producer.

Summary: This study demonstrated the antifungal activity of isolated Weissella cibaria BYL4.2 against Penicillium chrysogenum. The cell-free supernatant (CFS) produced by W. cibaria BYL4.2 showed pH-dependent and partly heat-sensitive antifungal activity, with lactic acid as the main component. D-tartaric acid, detected by non-targeted metabolomics analysis, was identified as the main antifungal substance of the CFS, which inhibited the growth of P. chrysogenum by down-regulating metabolites in the ABC transporters pathway.

Summary: The present study investigates the effects of fungi and bacteria metabolism on the crystallization patterns. The results demonstrate that Penicillium chrysogenum is capable of releasing both organic acids and extracellular polymer substance (EPS), which significantly impacts the pH of the culture liquid and the crystallization of carbonate and oxalate. The transition from oxalate crystallization to carbonate can occur with changes in microbial community composition and nutritional value medium. These findings contribute to the understanding of the role of fungi and bacteria in the oxalate-carbonate pathway.

Summary: In this study, a hybrid structure, MIL-53(Al)@MWCNT, was synthesized by combining MIL-53(Al) particles and -COOH functionalized multi-walled carbon nanotube (MWCNT). The hybrid structure was then embedded in a polyethersulfone (PES) polymer matrix to prepare a mixed matrix membrane (MMM) for CO2/CH4 and CO2/N2 separation. The addition of MWCNTs prevented MIL-53(Al) aggregation, improved membrane mechanical properties, and enhanced gas separation efficiency.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance. The reaction parameters and catalyst stability were also investigated.
