ABSTRACT Nitrite-dependent anaerobic oxidation of methane (n-damo) and ammonium (anammox) are two recently discovered processes in the nitrogen cycle that catalyzed by n-damo bacteria, including “ Candidatus Methylomirabilis oxyfera,” anammox respectively. The feasibility coculturing bacteria is important for implementation wastewater treatment systems contain substantial amounts both ammonium. Here we tested this possible coexistence experimentally. To obtain such a coculture, was fed to...
Anthropogenic nitrogen fixation is essential to sustain a global population of 7.7 billion. However, there has been long-standing desire find cheaper and more environmentally friendly alternatives the Haber–Bosch process. In this study, we developed new strategy by enriching free-living N2-fixing bacteria (NFB) in reactors fed with low wastewater, analogous those usually found certain industrial effluents such as paper mills. Our fixed appreciable quantities rate 11.8 mg N L–1 day–1. This...
Wastewater from the yeast production industry (WWY) is potentially harmful to surface water due its high nitrogen and organic matter content; it can be used produce compounds of higher commercial value, such as polyhydroxyalkanoates (PHA). PHA are polyester-type biopolymers synthesized by bacteria energy reservoirs that substitute petrochemical-derived plastics. In this exploratory work, effluent WWY was PHA, using a three-step setup mixed microbial cultures involving one anaerobic two...
Abstract Understanding the intricate ecological interactions within gut microbiome and unravelling its impact on human health is a challenging task. Bioreactors are valuable tools that have contributed to our understanding of microbial ecology. However, there lack studies describing comparing diversity cultivated in these models. This knowledge crucial for refining current models reflect gastrointestinal accurately. In this study, we analysed 1512 samples from 18 available public...
Background. The development of alternative processes to eliminate pathogenic agents in water is a matter growing interest. Current drinking disinfection procedures, such as chlorination and ozonation, can generate by-products with carcinogenic mutagenic potential are not readily applicable isolated rural communities less-favored countries. Solar particular interest treatment sunny regions the Earth. light may be used activate photocatalyst or photosensitizer that generates, presence...
Samples of natural groundwater (with low turbidity, neutral pH and 0.3 mg L-1 iron concentration) inoculated with Escherichia coli K-12 were exposed to simulated solar light both in the presence absence 10 H2 O2. Results demonstrated that viability E. (by DVC-FISH) was grounded zero after 360 min irradiation. This abatement could be caused by oxidative stress induced ·OH radicals or another photo-induced reactive oxygen species. Two 23 factorial experimental designs enabled evaluation...
is a pathogenic agent able to form biofilms on water storage tanks and pipe walls. This opportunistic pathogen can generate thick layer as one of its essential virulence factors, enabling the bacteria survive disinfection processes thus develop drug resistance.

Abstract Nitrogen‐fixing bacteria (NFB) can reduce nitrogen at ambient pressure and temperature. In this study, we treated effluent from a paper mill in sequencing batch reactors (SBRs) monitored the abundance activity of NFB with view to producing sludge that could work as biofertilizer. Four were inoculated activated enriched fed high C/N waste (100:0.5) mill. Though able organic load wastewater by up 89%, they did not have any nitrogen‐fixing showed decrease putative number (quantified...
In this work, TiO2 photocatalysis was used to disinfect domestic wastewaters previously treated by different biological treatment systems: Upward-flow Anaerobic Sludge Blanket (UASB), facultative pond, and duckweed pond. The microorganisms monitored were E. coli, total coliforms, Shigella species, Salmonella species. Photocatalytic experiments carried out using two light sources: a solar simulator (UV intensity: 68-70 W m-2) black-light lamps (BLL UV 17-20 m-2). Samples taken after each...
