TLDR
The results of high-throughput 16S rDNA sequencing showed that ammonia stress increased the relative abundance of Firmicutes bacteria and hydrogenotrophic methanogens but decreased the abundance of acetotrophic meethanogens, which was proposed to be an in situ response strategy for ammonia stress adaptation.About:

Effects of microplastics on wastewater and sewage sludge treatment and their removal: A review
Zhiqi Zhang,Yinguang Chen +1 more
TL;DR: In this article, the effects of microplastics on wastewater and sludge treatment and the mechanisms were discussed, and the problems that need to be addressed in the future were pointed out and the key points for future investigation were proposed.

Biogas from anaerobic digestion processes: Research updates
TL;DR: Anaerobic digestion (AD) is a biological process that can convert organic substrates to biogas in the absence of oxygen as mentioned in this paper, however, it is still a research focus in contemporary literature.
Journal ArticleDOI
Biogas production through syntrophic acetate oxidation and deliberate operating strategies for improved digester performance
TL;DR: This review summarises current insight of syntrophic acetate oxidising microorganisms, their presence and the detection of novel species and relate these observations with operating conditions of the biogas processes in order to explore contributing factors for development of an ammonia-tolerant microbial community that efficiently degrades acetate through the syntrophic pathway.
Journal ArticleDOI
Anaerobic digestion of food waste: A review focusing on process stability.
TL;DR: Process monitoring and control as well as microbial management can be used to control instability and increase the energy conversion efficiency of anaerobic digesters and existing limitations to efficient AD are identified.

Standard methods for the examination of water and wastewater
TL;DR: The most widely read reference in the water industry, Water Industry Reference as discussed by the authors, is a comprehensive reference tool for water analysis methods that covers all aspects of USEPA-approved water analysis.
Journal ArticleDOI
Inhibition of anaerobic digestion process: A review
TL;DR: This review provides a detailed summary of the research conducted on the inhibition of anaerobic processes and indicates that co-digestion with other waste, adaptation of microorganisms to inhibitory substances, and incorporation of methods to remove or counteract toxicants before an aerobic digestion can significantly improve the waste treatment efficiency.

The roles of acetotrophic and hydrogenotrophic methanogens during anaerobic conversion of biomass to methane: a review
B. Demirel,Paul Scherer +1 more
TL;DR: The aim of this paper is primarily to review the recent literature about the occurrence of both acetotrophic and hydrogenotrophic methanogens during anaerobic conversion of particulate biomass to methane (not wastewater treatment), while this review does not cover the activity of the acetate oxidizing bacteria.

Ammonia inhibition in anaerobic digestion: A review
Orhan Yenigun,Burak Demirel +1 more
TL;DR: Ammonia inhibition in anaerobic digestion systems and the recovery efforts after inhibition are discussed and the impacts of ammonia inhibition on the microbial population available in an aerobic digesters, namely bacteria and Archaea are evaluated in detail.
