TL;DR: The adverse long-term impact of the antibiotic tetracycline was quite variable for fermenting heterotrophic and methanogenic fractions of the microbial community based on changes inflicted on the composition of remaining/residual organic substrate.
179 citations
TL;DR: The hybrid UASB reactor could be a suitable alternative for the treatment of chemical synthesis-based pharmaceutical wastewater and the maximum loading capacity achievable before reactor failure was determined.
158 citations
TL;DR: Investigating the occurrence and variation in the ARGs found during the one-year operation of the anaerobic sequencing batch reactors used to treat pharmaceutical wastewater revealed that the effluent from the STE reactor had a higher number of ARGs than that from the ST reactor; this could be due to the synergistic effects of erythromycin.
145 citations
TL;DR: The investigation revealed that acetogens have a competitive advantage over Archaea in the presence of ETS and ST combinations, and the ETS batch reactor performed better than the ST batch reactor.

TL;DR: The relative abundance of dominant bacterial phyla during a biostimulation practice of petroleum contaminated soil has been evaluated through the Illumina sequencing method as discussed by the authors, and the results obtained from microcosm with the highest petroleum hydrocarbons removal rate, Proteobacteria, Firmicutes, and Bacteroidetes phyla, which composed about 50% of dominant organisms, proved to be the most influential on the biodegradation of soil.

TL;DR: In this article, a new method for metagenomic biomarker discovery by way of class comparison, tests of biological consistency and effect size estimation is described and validated, which addresses the challenge of finding organisms, genes, or pathways that consistently explain the differences between two or more microbial communities.
Abstract: This study describes and validates a new method for metagenomic biomarker discovery by way of class comparison, tests of biological consistency and effect size estimation. This addresses the challenge of finding organisms, genes, or pathways that consistently explain the differences between two or more microbial communities, which is a central problem to the study of metagenomics. We extensively validate our method on several microbiomes and a convenient online interface for the method is provided at http://huttenhower.sph.harvard.edu/lefse/.

TL;DR: In this paper, an L9(34) orthogonal table was adopted to design anaerobic digestion tests to evaluate the effect of ethanol, acetic acid, propionic acid, butyric acid and ethanol on methanogenic bacteria growth.
Abstract: Volatile fatty acids (VFAs) are important mid-products in the production of methane, and their concentrations affect the efficiency of fermentation. However, their effects on methane yield and methanogenic bacteria growth have been less extensively studied. To address these effects, acetic acid, propionic acid, butyric acid and ethanol were used as substrates and an L9(34) orthogonal table was adopted to design anaerobic digestion tests. When the highest concentrations of ethanol, acetic acid and butyric acid were 2400, 2400 and 1800 mg L−1, respectively, there was no significant inhibition of the activity of methanogenic bacteria. However, when the propionic acid concentration was increased to 900 mg L−1, significant inhibition appeared, the bacteria concentration decreased from 6 × 107 to 0.6–1 × 107 ml−1 and their activity would not reconvert. These effects resulted in the accumulation of ethanol and VFAs, and the total methane yield consequently became very low (<321 ml). The original propionic acid concentration had a significant inhibitory effect on methanogenic bacteria growth (P < 0.01). An optimization analysis showed that ethanol, acetic acid, propionic acid and butyric acid at concentrations of 1600, 1600, 300 and 1800 mg L−1, respectively, led to the maximum accumulative methane yield of 1620 ml and the maximum methanogenic bacteria concentration of 7.3 × 108 ml−1.
