Abstract ：
The pharmaceutical industry is a significant emission source of water-soluble volatile organic compounds (VOCs). However, these VOCs are primarily treated through adsorption on activated carbon or combustion methods, leading to high the generation of hazardous solid waste or energy consumption. This study proposed an innovative approach to address these issues by integrating spray absorption with biological treatment in sequencing batch reactors (SBRs). The results indicated that after spray absorption, more than 90 % of ethanol could be removed in SBRs, while 1-6 % of ethanol was emitted into the atmosphere, depending on aeration intensity and ethanol concentration. Although the intermittent emissions of ethanol gas resulted in a high variation in loading into the activated sludge system, stable and efficient treatment of ethanol was achieved. Amaricoccus was predominated as the primary bacterium responsible for ethanol degradation, indicating a robust microbial community capable of adapting to fluctuating ethanol levels. This study provides an environment-friendly and efficient solution to treating water-soluble VOCs. The proposed method utilizes existing infrastructure such as spray towers and biological treatment facilities commonly found in pharmaceutical enterprises, making it a cost-effective and easily implementable technology. This study contributes to the advancement of understanding in the field of VOCs treatment.

Abstract ：
There is very limited research on the application of moderate halophiles for biotreatment of hypersaline wastewater widely generated from some industries. This study demonstrated the development of moderate halophiles inoculated from saltern sediments into aerobic granule sludge (AGS) to treat hypersaline wastewater with a salinity of 100 g/L. The granulation of moderate halophiles can occur without applying the settling ve-locity selective pressure. The saltern sediment initially aggregated into single small granules and finally devel-oped into 1200 +/- 50 mu m multiparticle granules. The halophiles affiliated in Halomonas was dominant in the granular bacterial community, with a relative abundance of 94.52%. Halomonas ventosae secreted sulfated polysaccharides. The sulfated polysaccharides content accounted for 63.95 +/- 2.10% in the polysaccharides (PS), having an adhesive role in connecting single granules. Multiparticle granules showed the clear stratified struc-ture, with alpha-D-glucopyranose polysaccharides in the inner bounders and beta-D-glucopyranose polysaccharides in the outer. The moderately granular sludge showed the stable chemical oxygen demand (COD) removal efficiency of >90% and the aerobic total inorganic nitrogen (TIN) removal efficiency (equal to ammonia removal) of 70 +/- 5.00%. This paper contributes new insight into the formation of moderately halophilic granular sludge and accelerates the application of moderately halophilic granular sludge to treat hypersaline wastewater.

Abstract ：
Nitrogen and phosphate removal from wastewater relies on different functional bacteria. In this study, a novel strain affiliated with Pseudomonas aeruginosa was isolated from activated sludge by gradient dilution and per-formed heterotrophic nitrification-aerobic denitrification and aerobic phosphate removal (HNADPR). The strain showed an ammonium removal efficiency of 87% and a phosphate removal efficiency of 97% under optimal conditions, such as C/N ratio of 10, P/N ratio of 0.1, temperature of 30C, and pH of 7.5-8.5. The modified Gompertz model could fit well the heterotrophic ammonium nitrification, aerobic nitrite/nitrate denitrification, and aerobic phosphate removal processes. Functional gene amplification indicated that ammonium removal followed the complete HN-AD pathway (NH4+ -> NH2OH -> NO2- -> NO3? -> NO2- -> NO -> N2O -> N-2). Phosphate removal only occurred under aerobic conditions and ceased under anaerobic conditions. In successive aerobic cycles, the strain persistently took up phosphate. In wastewater, phosphate was aerobically converted into cell membrane, intracellular and extracellular polymeric substrates (EPS). Phosphorus in the form of phosphate monoester was pooled in EPS. A hypothetic aerobic phosphate removal model for strain SNDPR-01 is proposed to improve our understanding of the novel bacterial function of HNADPR.

Abstract ：
BACKGROUND Contact stabilization (CS) can be used to capture organic matters from wastewater. However, CS is less efficient in capturing soluble organic matters (SOMs). Recovery of SOMs is required to minimize carbon emission and to maximize organic recovery from wastewater. RESULTS SOMs were recovered by applying a feast/famine (F/F) regime in a CS process. Sludge retention time (SRT) was found to regulate the recovery efficiency of SOMs. At a SRT of 4 d, 44.7% of the removed soluble chemical oxygen demand (SCOD) in wastewater was recovered and stored into intracellular polyhydroxyalkanoates (PHA), leading to 12.8% decrease of CO2 emission in comparison with the conventional activated sludge process. The storage of PHA in waste sludge harvested at a SRT of 4 d significantly increased the methane yield (187.3 +/- 5.9 mL (g VSS)(-1)). The dominant bacteria performing SOM recovery in CS belonged to the genera Tessaracoccus, norank_f__Caldilineaceacea, unclassified_f__Microbacteriaceae and Flavobacterium. CONCLUSIONS The study demonstrated that applying F/F regime in a CS process can recover SOMs via PHA storage. The regulation of SRT can enhance SCOD recovery. The study provides a solution to enhance SOM recovery from wastewater instead of being oxidized into CO2. (c) 2022 Society of Chemical Industry (SCI).

Abstract ：
Low polyhydroxyalkanoate (PHA) volumetric productivity from wastewater limits low-cost PHA production. To resolve this problem, an external magnetic field (MF) coupled with upshock salinity was applied to PHA production by Haloferax mediterranei (family Halobacteriaceae). Elevating the fermentation salinity over the optimal growth salinity (200 g/L) increased the PHA cell content while inhibiting cell proliferation, decreasing volumetric productivity. When a MF of 50 mT in 300 g/L salinity was applied, H. mediterranei proliferation and PHA cell content were promoted, leading to a 7.95% increase in PHA volumetric productivity in synthetic molasses wastewater and a 13.82% increase in glucose feeding compared with those in 200 g/L salinity. Under the MF, osmotic pressure regulation was activated by accumulating K1 and increasing betaine synthesis. The maximum betaine content increased by 74.33% in 300 g/L salinity with a 50-mT MF compared with that in 200 g/L salinity. When a 50-mT MF in 300 g/L salinity was applied, the malondialdehyde (MDA) content decreased by 32.66% and the activity of superoxide dismutase (SOD) increased by 46.89%, which reduced the oxidative damage. This study provides a new solution to enhance PHA volumetric productivity by MF and an insight into the magnetic effects of H. mediterranei. IMPORTANCE The obstacle to replacing petroplastics with PHA is its high production cost. To increase the fermentation economy, a novel strategy of coupling a MF with salinity upshock was applied, which enhanced the PHA volumetric productivity of H. mediterranei in fermenting molasses wastewater. The magnetic effect of H. mediterranei was found at a MF of 50 mT, which improved the salt tolerance of H. mediterranei and reduced the oxidative damage induced by the elevated salinity, thereby promoting proliferation and PHA cell content. This is the first time a technical method for enhancing PHA volumetric productivity by means of a MF has been proposed. Such a strategy can advance the utilization of H. mediterranei for the industrial production of PHA using organic wastewater. Copyright © 2022 American Society for Microbiology. All Rights Reserved.

Abstract ：
Heterotrophic nitrification-aerobic denitrification (HN-AD) is a novel alternative for nitrogen removal due to simultaneous nitrification and denitrification that occurs under aerobic conditions. Until now, ways in which to achieve aerobic nitrogen removal from wastewater via the HN-AD process have not been fully explored. In this study, autotrophic nitrification was converted into HN-AD in a halophilic aerobic granular sludge (HAGS) system when the wastewater salinity decreased from 30 to 20 g/L. Bacteria affiliated to the genus Paracoccus were dominant in the HAGS with a relative abundance of 56%, functioning with HN-AD. Accordingly, the indicative gene napA encoding for HN-AD was 5.1 x 10(9) copies/g HAGS. HAGS performing HN-AD exhibited a stable total inorganic nitrogen (TIN) removal efficiency performance in response to salinity variations of 10-40 g/L, owing to the stable HN-AD functional community. The significant inhibition of HN-AD was observed in both low salinity (& LE;5 g/L) and high salinity (& GE;50 g/L) conditions, accompanied by the disintegration of granules. Granular disintegration was triggered by the lower secretion of extracellular polymeric substances and alginate-like exopolysaccharides. HAGS performing HN-AD could simultaneously remove chemical oxygen demand and TIN from saline wastewater in a single aerobic tank, thus reducing the construction and operation costs.

Abstract ：
Sulfur-driven autotrophic denitrification (SADN) is a promising technology for nitrogen removal from wastewater. In this study, different-strength SMFs (0, 5, 20, 50, 70 mT) were evaluated to investigate the potential of external static magnetic field (SMF) for enriching sulfur-oxidizing autotrophic denitrifiers (SOAD). 50-mT and 70-mT SMFs were most suitable to accelerate the growth of SOAD and the elimination of non-SOAD. The relative abundance of Thiobacillus significantly increased (p < 0.01) from 6.26% in control reactor to 36.15% under 50 mT and 52.51% under 70 mT. Under 50 mT, Thiobacillus denitrificans accumulated most rapidly, with the largest population. Furthermore, functional gene forecast by high-throughput and metagenomic sequencing indicated that SMF changed the two-component system, the adenosine 5'-monophosphate-activated protein kinase (AMPK) signaling system, the phosphotransferase system (PTS), as well as N/S-related enzymes to regulate stress response and promote the growth of SOAD. The findings indicated that SMF accelerated the start-up of SADN.
