  • Shewanella decolorationis sp. nov., a dye-decolorizing bacterium isolated from activated sludge of a Waste-Water Treatment plant
    International Journal of Systematic and Evolutionary Microbiology, 2005
    Co-Authors: Meiying Xu, Yinghua Cen, Xiaoyan Zhong, Wei Cao, Jun Guo, Guoping Sun
    Abstract:

    A highly efficient dye-decolorizing bacterium, strain S12T, was isolated from activated sludge of a textile-printing Waste-Water Treatment plant in Guangzhou, China. The cells were Gram-negative and motile by means of a single polar flagellum. The strain was capable of anaerobic growth either by fermentation of glucose or by anaerobic respiration and utilized a variety of electron acceptors, including nitrate, iron oxide and thiosulfate. The physiological properties, tested by using the Biolog GN2 system, were similar to those of the genus of Shewanella. Analysis of the nearly complete 16S rRNA gene sequence of strain S12T showed the highest similarity (98 and 97 %, respectively) to Shewanella baltica and Shewanella putrefaciens. However, the level of gyrB similarity between strain S12T and S. putrefaciens was 87 %. DNA from strain S12T showed 41.8 and 41.9 % DNA relatedness, respectively, to the DNA of S. baltica DSM 9439T and S. putrefaciens DSM 6067T. The DNA G+C content of strain S12T was 49.3 mol%. The predominant menaquinone was MK-7 and the predominant ubiquinones were Q-7 and Q-8. The dominant fatty acids were 15 : 0, 16 : 0, iso-15 : 0 and 16 : 1omega7c, similar to the profiles of other Shewanella species. On the basis of its physiological and molecular properties, strain S12T appears to represent a novel species of the genus Shewanella, for which the name Shewanella decolorationis sp. nov. is proposed. The type strain is S12T (=CCTCC M 203093T=IAM 15094T).

  • nitrogen removal performance in pilot scale solid phase denitrification systems using novel biodegradable blends for Treatment of Waste Water Treatment plants effluent
    Bioresource Technology, 2020
    Co-Authors: Zhongchen Yang, Haimeng Sun, Qi Zhou, Liu Zhao
    Abstract:

    Abstract In this study, three pilot-scale solid-phase denitrification (SPD) systems filled with poly-3-hydroxybutyrate-co-hyroxyvelate (PHBV), PHBV-Rice hulls (PHBV-RH) and PHBV-Sawdust (PHBV-S) were operated to treat effluent of Waste Water Treatment pangts (WWTPs). The fast start-up and intensified nitrogen removal performance were obtained in PHBV-RH and PHBV-S systems. Besides, the optimal total nitrogen (TN) removal efficiency was obtained in PHBV-S system (91.65 ± 4.12%) with less ammonia accumulation and dissolved organic carbon (DOC) release. The significant enrichment of amx 16S rRNA and nirS genes in PHBV-RH and PHBV-S systems indicated the possible coexistence of anammox and denitrification. Miseq sequencing analysis exhibited more complex community diversity, more abundant denitrifying and fermenting bacteria in PHBV-RH and PHBV-S systems. The co-existence of denitrification and anammox might contribute to better control of nitrogen and dissolved organic carbon in PHBV-S system. The outcomes provide an economical and eco-friendly alternative to improve nitrogen removal of WWTPs effluent.

  • simultaneous removal of nitrogen and pharmaceutical and personal care products from the effluent of Waste Water Treatment plants using aerated solid phase denitrification system
    Bioresource Technology, 2019
    Co-Authors: Ting Wang, Zhongchen Yang, Cecilia Yu, Weizhong Wu
    Abstract:

    Abstract Nowadays, Waste Water Treatment plants (WWTPs) are regarded as the pollution sources of nitrogen and pharmaceutical and personal care products (PPCPs). In the present study, the simultaneous removal of nitrogen and typical PPCPs, ibuprofen and triclosan, was evaluated in a poly-3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV) based solid-phase denitrification (SPD) system. Results after 602 days showed that simultaneous nitrification and denitrification (SND) process occurred with average 83.85 ± 13.09% NH4+-N and 93.88 ± 10.19% NO3−-N removals in the SPD system. Interestingly, the system achieved average 79.69 ± 6.35% and 65.96 ± 7.62% removals of ibuprofen and triclosan, respectively, under stable influent conditions of 50 μg L−1. Cometabolic activities of heterotrophic denitrifying bacteria and ammonia oxidizing bacteria (AOB) probably played a role in the biodegradation of the two PPCPs. Illumina MiSeq sequencing results revealed that microbial composition enhanced the simultaneous removal of nitrogen and PPCPs in the SPD system.
