Changes of microbial composition during wastewater reclamation and distribution systems revealed by high-throughput

Yiwen LIN,Dan LI,Siyu ZENG,Miao HE

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 3,   Pages 539-547 doi: 10.1007/s11783-016-0830-5

Abstract: This study employed 454-pyrosequencing to investigate microbial and pathogenic communities in two wastewater reclamation and distribution systems. A total of 11972 effective 16S rRNA sequences were acquired from these two reclamation systems, and then designated to relevant taxonomic ranks by using RDP classifier. The Chao index and Shannon diversity index showed that the diversities of microbial communities decreased along wastewater reclamation processes. was the most dominant phylum in reclaimed water after disinfection, which accounted for 83% and 88% in two systems, respectively. Human opportunistic pathogens, including , , and , were selected and enriched by disinfection processes. The total chlorine and nutrients (TOC, NH -N and NO -N) significantly affected the microbial and pathogenic communities during reclaimed water storage and distribution processes. Our results indicated that the disinfectant-resistant pathogens should be controlled in reclaimed water, since the increases in relative abundances of pathogenic bacteria after disinfection implicate the potential public health associated with reclaimed water.

Process stability and microbial community composition in pig manure and food waste anaerobic co-digesters

Conor Dennehy, Peadar G. Lawlor, Gillian E. Gardiner, Yan Jiang, Paul Cormican, Matthew S. McCabe, Xinmin Zhan

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 3, doi: 10.1007/s11783-017-0923-9

Abstract: This study assessed the effects of reducing hydraulic retention times (HRTs) from 21 days to 10.5 days when anaerobically co-digesting pig manure and food waste. Continuously stirred tank reactors of 3.75 L working volume were operated in triplicate at 42°C. Digester HRT was progressively decreased from 21 to 15 days to 10.5 days, with an associated increase in organic loading rate (OLR) from 3.1 kg volatile solids (VS)·m ·day to 5.1 kg VS·m ·day to 7.25 kg VS·m ·day . Reducing HRT from 21 days to 15 days caused a decrease in specific methane yields and VS removal rates. Operation at a HRT of 10.5 days initially resulted in the accumulation of isobutyric acid in each reactor. High throughput 16S rRNA gene sequencing revealed that this increase coincided with a shift in acidogenic bacterial populations, which most likely resulted in the increased isobutyric acid concentrations. This may in turn have caused the increase in relative abundance of bacteria, which syntrophically degrade non-acetate volatile fatty acids (VFAs) into H and CO . This, along with the increase in abundance of other syntrophic VFA oxidizers, such as suggests that VFA oxidation plays a role in digester operation at low HRTs. Reducing the HRT to below 21 days compromised the ability of the anaerobic digestion system to reduce enteric indicator organism counts below regulatory limits.
