Summary: The study investigated the use of cheese whey and olive mill wastewater as feedstocks to produce bacterial cellulose using acetic acid bacteria strains. The composition of organic acids and phenolic compounds was analyzed, and various techniques were used to study the chemical and morphological changes in bacterial cellulose. Cheese whey was found to be the most efficient feedstock, while bacterial cellulose produced in olive mill wastewater had a more well-defined network and smaller fiber diameter. The study also analyzed the chemical structure of the bacterial cellulose and identified different chemical bonds. The high versatility in yield, morphology, and fiber diameters obtained from cheese whey and olive mill wastewater contribute to the development of customized bioprocesses for bacterial cellulose.

Summary: This study investigates the influence of alkali impurities and silica content in rice husk ash (RHA) on the alkali silica reaction (ASR) of mortar. Three types of RHAs with varying alkali content and amorphous silica were used. The study analyzes the effect of RHA type, particle size, and substitution proportion on mechanical properties and expansion level of mortar. It also examines the impact of RHA type on hydration products, hydrates pattern, and pore structure. The results indicate that RHA particle size and amorphous silica content are key factors affecting the compressive strength of mortar blended with RHA. An innovative finding suggests that RHA particles can act as reactive aggregates, reacting with potassium and alkali ions to create alkali silica gel. The mechanism for pozzolanic reaction and two ASRs in RHA is presented. Two ASRs were observed in GRHA particles, leading to significant expansion and cracks in mortar, while WRHA only reacted with alkali ions, resulting in slight expansion and no cracks in mortar. Overall, the importance of this paper is rated 8 out of 10.

Summary: The presence of protein, carbohydrate, and lipids in dairy wastewater reduces its biological treatment efficiency, but separating these compounds can improve treatment efficiency by using them for animal feed or enhancing existing wastewater treatment facilities. Pressure-driven membrane technologies like ultrafiltration UF, nanofiltration NF, and reverse osmosis RO can result in fouling due to the presence of protein and carbohydrate, but forward osmosis FO offers a less fouling solution for dairy wastewater treatment. An integrated treatment process with UF followed by FO has shown significant retention of carbohydrates and proteins in dairy wastewater treatment.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
