Assessing the impact of lime on chromium migration in soil caused by basic chromium sulfate in tannery

Li-jie Song et al.

Summary: Column leaching tests were conducted to investigate the transport and transformation of chromium (Cr) from basic chromium sulfate (BCS) in soil, as well as the effects of lime. The results showed that BCS leached out mainly as Cr(VI) and the concentration of leached Cr decreased with increased thickness of BCS. The presence of lime reduced the migration and toxicity of BCS in soil. Analysis of soil bacterial community revealed an increase in the relative abundance of Proteobacteria, with Burkholderiaceae being the dominant family in BCS contaminated soil.

Membrane penetration of nitrogen and its effects on nitrogen removal in dual-chambered microbial fuel cells

Xiaojun Jin et al.

Summary: A novel method of nitrogen removal through membrane penetration was proposed in a dual-chamber microbial fuel cell with a proton exchange membrane (PEM). The study showed that NH4+-N migrated rapidly across the PEM, with 50% being oxidized to NO3 -N in the cathode chamber and the remaining being eliminated through short-cut nitrification/denitrification. Additionally, NO3 -N crossed the PEM again and was reduced via anodic denitrification. The functional microorganisms in the anode and cathode were found to have different compositions.

Spatial distribution and nitrogen metabolism behaviors of anammox biofilms in bioelectrochemical system regulated by continuous/intermittent weak electrical stimulation

Teng Cai et al.

Summary: A study was conducted on the effect of weak electrical stimulation on biofilms in a bioelectrochemical anammox system. Continuous stimulation was found to enhance the electron transfer system activity and nitrogen removal, while also facilitating the secretion of extracellular polymer substances and promoting the formation of compact biofilms. Microbial analysis showed an increase in specific microorganisms, indicating the importance of weak electrical stimulation in diversifying the microbial community and creating a robust nitrogen metabolic pathway.

The nitrification recovery capacity is the key to enhancing nitrogen removal in the AOA system at low temperatures

Xinjie Gao et al.

Summary: This study investigated the nitrogen removal performance of AOA process at low and room temperatures. The results showed that the nitrification capacity of AOA process was recovered at low temperature and the endogenous denitrification performance was enhanced by converting the partial aerobic zone into anoxic. The activity and abundance of ammonia-oxidizing bacteria (AOB) increased at low temperature, which was the key for nitrification capacity recovery. Overall, AOA system showed the possibility of advanced nitrogen removal at low temperatures.

Qingqing Pang et al.

Summary: This study used a two-stage tidal flow constructed wetland to treat low C/N ratio influent, investigating the impact of flooding-resting time and effluent recirculation on nitrogen removal and microbial community characteristics. The results showed that nitrogen removal efficiency and microbial community composition were influenced, with TFCW-B leading to nitrate nitrogen accumulation due to lack of a carbon source and longer resting time.

Comprehensive performance, bacterial community structure of single-chamber microbial fuel cell affected by COD/N ratio and physiological stratifications in cathode biofilm

Jianqi Yuan et al.

Summary: This study compared the effects and bacterial community structure of single-chamber microbial fuel cells (MFCs) in treating NH4+-containing wastewater with different COD/N ratios. Results showed that MFCs with low COD/N had better NH4+-N removal and electrochemical performance, while MFCs with high COD/N had better removal stability and COD removal effect. High-throughput sequencing revealed that the anode community structure was weakly affected by the COD/N ratio, with Geobacter dominating, but the cathode community was complex and susceptible to the COD/N ratio. pH profiling in the cathode biofilm and FISH were used to confirm the distribution trends of nitrifiers and denitrifiers.

Mini-metagenome analysis of psychrophilic electroactive biofilms based on single cell sorting

Yang Yang et al.

Summary: Understanding the metabolic function of psychrophilic electroactive bacteria is crucial for studying extracellular electron transfer mechanisms under low temperatures. Through Raman activated cell ejection coupled high throughput sequencing, it was found that psychrophilic bacteria in biofilm communities have a high abundance of membrane transport functional genes ftsEX, indicating adaptation to low temperatures and maintenance of the electron pool for EET process. The identification of iron (Ill) transport system genes in high abundance suggests active metabolic reaction for potential electron transfer process mediated by c-type cytochromes.
