Deciphering Bisphenol A degradation by Coelastrella sp. M60: Unravelling metabolic insights through metabolomics analysis
This study mainly investigated the BPA degradation by Coelastrella sp. M60 at various concentrations (10 to 50 mg/L) using GC-MS analysis. Further, the metabolic profiling of Coelastrella sp. M60 was performed via the MetaboAnalyst and results revealed that BPA exposure modulated the metabolites profile with the presence of intermediates like 4-hydroxybenzoic acid and benzene. Moreover, the highest lipid (54 %) and pigment content (40 %) at 10 mg/L of BPA exposure. Fatty acid methyl esters were quantified in Coelastrellasp. M60, with enhanced recovery facilitated by Cuprous oxide nanoparticle (Cu2O NPs) synthesized from Sp...

Enhancement of bio-promoters on hexavalent chromium inhibited sulfur-driven denitrification: repairing damage, accelerating electron transfer, and reshaping microbial collaboration
This study proposed an effective bio-promoter (mediator-promoter composed of L-cysteine, biotin, cytokinin, and anthraquinone-2,6-disulfonate) to recover Cr(VI) inhibited sulfur-driven denitrification, which effectively reduced the recovery time of NO3--N reduction (18-21 cycles) and NO2--N reduction (27-42 cycles) compared with self-recovery. The mediator-promoter repaired microbial damage by promoting intracellular chromium efflux. Moreover, the mediator-promoter reduced the accumulated reactive oxygen species by stimulating the secretion of antioxidant enzymes, reaching equilibrium in the oxidative-antioxidant system. T...

Enhanced biobased carbon materials made from softwood bark via a steam explosion preprocessing step for reactive orange 16 dye adsorption
This study investigates a novel preprocessing method for producing activated carbons from abundantly available softwood bark. The preprocessing involved a continuous steam explosion preconditioning step, chemical activation with ZnCl2, pyrolysis at 600 and 800 °C, and washing. The activated carbons were subsequently characterized by SEM, XPS, Raman and FTIR prior to evaluation for their effectiveness in adsorbing reactive orange 16 and two synthetic dyehouse effluents. Results showed that the steam-exploded carbon, pyrolyzed at 600 °C, obtained the highest BET specific surface area (1308 m2/g), the best Langmuir maximum ...

Online ahead of print.ABSTRACTTo improve nitrogen removal efficiency (NRE) and achieve homogenous distribution of anammox sludge and substrate, a new substrate equalization theory and a cumulative overload index was proposed for multifed upflow anaerobic sludge bed (MUASB) reactors with mature anammox granules. The performance and flow patterns of MUASB reactors were investigated under various influent conditions. The results showed that the nitrogen removal performance and stability of MUASB reactors could be optimized by minimizing the cumulative...
