“…The lower ammoniacal nitrogen removal efficiency (3–14 %) was observed for the other isolated bacteria, this may be due to that they do not possess the abilities like B. panacihumi strain ZB1 has, where it is an aerobic bacteria that works well under aerobic condition. In addition, the strain belongs to Brevibacillus genus which is able to reduce nitrate (Li et al 2015). Therefore, this bacterial strain was chosen for further studies.…”

Sanitary landfilling is the most common way to dispose solid urban waste; however, improper landfill management may pose serious environmental threats through discharge of high strength polluted wastewater also known as leachate. The treatment of landfill leachate to fully reduce the negative impact on the environment, is nowadays a challenge. In this study, an aerobic sequencing batch reactor (ASBR) was proposed for the treatment of locally obtained real landfill leachate with initial ammoniacal nitrogen and chemical oxygen demand (COD) concentration of 1800 and 3200 mg/L, respectively. ASBR could remove 65 % of ammoniacal nitrogen and 30 % of COD during seven days of treatment time. Thereafter, an effective adsorbent, i.e., zeolite was used as a secondary treatment step for polishing the ammoniacal nitrogen and COD content that is present in leachate. The results obtained are promising where the adsorption of leachate by zeolite further enhanced the removal of ammoniacal nitrogen and COD up to 96 and 43 %, respectively. Furthermore, this combined biological–physical treatment system was able to remove heavy metals, i.e. aluminium, vanadium, chromium, magnesium, cuprum and plumbum significantly. These results demonstrate that combined ASBR and zeolite adsorption is a feasible technique for the treatment of landfill leachate, even considering this effluent’s high resistance to treatment.

“…These results may be due to the formation of more reactive species (such as HO · and O·) and electrons during the discharge process of the NTP reactor and the subsequent oxidation of more chlorobenzene molecules to CO and CO 2 . 34 They also indicate that CO 2 production was partially related to chlorobenzene degradation.…”

BACKGROUND Non‐thermal plasma (NTP) combined with a biotrickling filter (BTF) system is an alternative process to remove volatile organic compounds (VOCs). The removal performance of this system and the factors that influence it, namely, initial concentration, specific input energy, empty‐bed residence time, and inlet loading rate, were studied. RESULTS The coupled system exhibited better removal of chlorobenzene compared with the single‐BTF system. Analysis of CO2 production revealed that the coupled system affords higher production of CO2 and greater mineralization of chlorobenzene. A decrease in biomass accumulation and pressure drop in the coupled system greater than that in the single‐BTF reactor were observed. These results indicate that NTP pretreatment may be an efficient strategy for reducing bioreactor clogging without damaging the BTF performance. Analysis of the alpha diversity and microbial communities of the two BTFs by high‐throughput sequencing revealed that the biological diversity and biomass content of the single‐BTF system were higher than those of the coupled system. CONCLUSION Since the combined NTP–BTF system is highly efficient, it may be a promising system for VOCs degradation. © 2016 Society of Chemical Industry

The increasing public expectations for good air quality have necessitated the development of biodeodorization technology. In this study, a novel heterotrophic Pseudomonas strain was isolated from biogas slurry and its biodesulfurization ability was investigated. The optimization of culture conditions determined 30 ℃ and 200 rpm as the optimal temperature and shaking speed. Under such conditions, 50 mM thiosulfate was completely consumed. The whole genome sequencing and functional annotation identified the genes associated with sulfur metabolism and the RT-qPCR analysis quantified the expression level of corresponding genes. The results showed that this strain was able to convert thiosulfate to sulfane, which could be decomposed into elemental sulfur and therefore achieved desulfurization. However, this process was relatively weak as most thiosulfate was converted into soluble tetrationate catalyzed by gene tsdA. Further research would focus on the enhancement of sulflane production pathway through metabolic engineering tools.
