To understand the relationship between elevation and bacterial communities in wastewater treatment plants (WWTPs), bacterial communities in 21 municipal WWTPs across China, located 9 to 3,660 m above sea level (masl), were investigated by 454 pyrosequencing. A threshold for the association of elevation with bacterial community richness and evenness was observed at approximately 1,200 masl. At lower elevations, both richness and evenness were not significantly associated with elevation. At higher elevations, significant declines with increased elevations were observed for community richness and evenness. The declining evenness trend at the phylum level was reflected by distinct trends in relative abundance for individual bacterial phyla. Betaproteobacteria, Bacteroidetes, and Firmicutes displayed significant increases, while most other phyla showed declines. Spearman correlation analysis indicated that the community richness and evenness at high elevations were more correlated with elevation than with any other single environmental variable. Redundancy analysis indicated that the contribution of elevation to community composition variances increased from 3% at lower elevations to 11% at higher elevations whereas the community composition variance at higher elevations remained much more explained by operational variables (39.2%) than by elevation. The influent total phosphorus concentration, food/microorganism ratio, and treatment process were the three shared dominant contributors to the community composition variance across the whole elevation gradient, followed by effluent ammonia nitrogen and temperature at higher elevations. W astewater treatment plants (WWTPs) are broadly applied for the efficient removal of contaminants from wastewater before its discharge into the natural environment. A complex microbial community is the most dominant contributor to the removal of contaminants in WWTPs. A better understanding of the microbial community structure and its relationship to influential variables could provide important guidance for the improvement of wastewater treatment efficiency (1). Multiple studies have investigated the significant associations between WWTP microbial community structures and operational parameters or wastewater characteristics, such as dissolved oxygen concentration (2), temperature (3), treatment process (4), influent ammonia nitrogen concentration (5), biological oxygen demand (6), and total phosphorus (TP) concentration (7). However, regardless of the weakly neutral assembly of bacterial communities (8), there is still a large part of the bacterial community variance that cannot be explained by these well-known variables. Thus, it is presumed that there are still other environmental variables that potentially influence the variance of WWTP microbial communities.In recent years, a few studies were performed to explore the relationship between microbial communities and geographical locations of WWTPs. Zhang et al. (9) found significant geographical differences in bacterial communities amo...

“…The rate of petrol degradation was maximum (31.9%) at the end of 15 days interval period by Achromobacter. Recently, Achromobacter sp has been reported to utilize polycyclic aromatic hydrocarbons [46][47][48][49][50]. PAH degradation by Pseudomonas strains is well characterized [51].…”

Polycyclic aromatic hydrocarbons (PAHs) are common environmental pollutants and biodegradation using microorganisms is the preferred and major route of PAH removal from contaminated environments. This study investigated the bacterial degradation of petrol and diesel in liquid media that were isolated from oil contaminated soils by enrichment technique. The isolates could use petrol and diesel as their sole carbon and energy source in Bushnell Hass Mineral Salts (BHMS) medium at 2% (v/v) concentration. A total of eight isolates were selected and characterized by using a variety of phenotypic and morphologic properties. Two isolates each showed highest growth in petrol and diesel containing media during screening were selected and characterized using 16S RNA sequencing. Molecular identification of the isolates assigned them to Achromobacter sp. and Pseudomonas aeruginosa. The selected isolates degraded petrol and diesel up to 31.9% and 34.4% respectively. This study indicates that the contaminated soil samples contain a diverse population of PAH-degrading bacteria and the use of Achromobacter sp. and Pseduomonas aeruginosa has the potential for bioremediation of PAH contaminated sites.

Crude oil is a major pollutant of marine and coastal ecosystems, and it causes environmental problems more seriously. It is believed ultimate and complete degradation is accomplished mainly by microorganisms. In this study, we aim to search out for bacterial strains with high ability in degrading crude oil. From sediments contaminated by the petroleum spilled in 2007, an accident in Taean, South Korea, we isolated thirty‐one bacterial strains in total with potential application in crude oil contamination remediation. In terms of removal percentage after 7 days, one of the strains, Co17, showed the highest removal efficiency with 84.2% of crude oil in Bushnell‐Haas media. The Co17 strain even exhibited outstanding ability removing crude oil at a high salt concentration. Through the whole genome sequencing annotation results, many genes related with n ‐alkane degradation in the genome of Gordonia sp. Co17, revealed alkane‐1‐monooxygenase, alcohol dehydrogenase, and Baeyer–Villiger monooxygenase. Specially, for confirmation of gene‐level, alk B gene encoding alkane hydroxylase (alkane‐1‐monooxygenase) was found in the strain Co17. The expression of alk B upregulated 125‐fold after 18 hr accompany with the removal of n ‐alkanes of 48.9%. We therefore propose the strain Gordonia iterans Co17, isolated from crude oil‐contaminated marine sediment, could be used to offer a new strategy for bioremediation with high efficiency.
