“…Similar to the results of this study, the dominance of Betaproteobacteria (higher taxa) has been frequently observed in phenol degradation systems, including CWW (Manefield et al 2005;Zhu et al 2013Zhu et al , 2016Ma et al 2015a;Wang et al 2015b) petroleum refinery, pharmaceutical (Ibarbalz et al 2013), and municipal Wang et al 2012;Hai et al 2014;Shu et al 2015) wastewater treatment plants, as well as in different types of bioreactors (Wagner and Loy 2002). This highlights the rapid a c c l i m a t i z a t i o n a n d m e t a b o l i c s i g n i f i c a n c e o f Betaproteobacteria in the removal of a wide range of pollutants, including phenolic compounds from CWW.…”

“…Chemolithotrophic sulfur oxidizing bacteria Thiobacillus, Comamonas, and Diaphorobacter can also oxidize thiosulfate (Shoji et al 2014;Narayan et al 2010;Pham et al 2009), thereby contributing increased concentrations of sulfate in aerobic effluent. Ma et al (2015a) and Zhu et al (2016) also observed a higher abundance of Thiobacillus and Comamonas in aerobic activated sludge treating CWW. Additionally, certain species of detected bacteria, such as Comamonas and Ottowia, are floc-forming bacteria (Tago and Yokota 2004;Felföldi et al 2010) and might play significant roles in active sludge structure formation, and hence contribute to the stability of the aerobic system.…”

“…The absence of nitrifying bacteria in the aerobic sludge (Table S5) might be due to insufficient HRT (72 h) or an inhibitory effect of toxic compounds . Ma et al (2015a) also reported relatively low abundance (<1 %) of ammonia and nitrite oxidizing bacteria in activated sludge of CWW treatment plants. Increased HRT, a maintained C/N ratio, and recycling of sludge may improve ammonia removal (Chakraborty and Veeramani 2006;Lai et al 2008).…”

“…Since these microbial populations are associated with pollutant removal efficiency, understanding community structure in different stages during long-term operated CWW treatment is important. Previous studies have focused on bacterial diversity surveys in full-scale CWW treatment systems, revealing the distribution of potential degraders of phenols, SCN − , and CN − (Zhu et al , 2016Ma et al 2015a;Wang et al 2015b). However, to better understand the profiles of acclimatized bacterial, archaeal, and fungal communities associated with degradation of different pollutants, research on controlled sequential anaerobic and aerobic CWW treatment systems is desirable.…”

The combined anaerobic-aerobic biosystem is assumed to consume less energy for the treatment of high strength industrial wastewater. In this study, pollutant removal performance and microbial diversity were assessed in a longterm (over 300 days) bench-scale sequential anaerobicaerobic bioreactor treating coking wastewater. Anaerobic treatment removed one third of the chemical oxygen demand (COD) and more than half of the phenols with hydraulic retention time (HRT) of 42 h, while the combined system with total HRT of 114 h removed 81.8, 85.6, 99.9, 98.2, and 85.4 % of COD, total organic carbon (TOC), total phenols, thiocyanate, and cyanide, respectively. Two-dimensional gas chromatography with time-of-flight mass spectrometry showed complete removal of phenol derivatives and nitrogenous heterocyclic compounds (NHCs) via the combined system, with the anaerobic process alone contributing 58.4 and 58.6 % removal on average, respectively. Microbial activity in the bioreactors was examined by 454 pyrosequencing of the bacterial, archaeal, and fungal communities. Proteobacteria (61.2-93.4 %), particularly Betaproteobacteria (34.4-70.1 %), was the dominant bacterial group. Ottowia (14.1-46.7 %), Soehngenia (3.0-8.2 %), and Corynebacterium (0.9-12.0 %), which are comprised of phenol-degrading and hydrolytic bacteria, were the most abundant genera in the anaerobic sludge, whereas Thiobacillus (6.6-43.6 %), Diaphorobacter (5.1-13.0 %), and Comamonas (0.2-11.1 %) were the major degraders of phenol, thiocyanate, and NHCs in the aerobic sludge. Despite the low density of fungi, phenol degrading oleaginous yeast Trichosporon was abundant in the aerobic sludge. This study demonstrated the feasibility and optimization of less energy intensive treatment and the potential association between abundant bacterial groups and biodegradation of key pollutants in coking wastewater.

“…As revealed by high throughput 454 pyrosequencing of amplicons, Zoogloea was one of the dominant genera and existed in high abundance (1.38e11.1%) in most of the AS samples from the municipal sewage treatment plants of mainland China, Hong Kong, Singapore, Canada, and United States (Zhang et al, 2012;Wang et al, 2012). However, Zoogloea was not the predominant species in the industrial wastewater-treating activated sludge (Ibarbalz et al, 2013;Ma et al, 2015).…”
