Testing for the Environmental Fate and Safety of E-Waste using Nitrobacter and Mice Model
International Journal of Environment Agriculture and Biotechnology, 2020 The present study aimed to test for the environmental fate and safety of e-waste using Nitrobacter sp. and mice model assays. The Nitrobacter sp. toxicity test was designed in four treatments and control setups namely 6.25, 12.5, 25, 50 % and control ...

Eco-toxicological effects of pesticide residues on soil biological sentinels
Journal of Applied Sciences and Environmental Management, 2018 This research studied the eco-toxicological effects of pesticide residues on soil biological sentinels. Nitrobacter and Nitrosomonas sp. was isolated from Soil samples gotten from dumpsite in Benin City and cultured using Winogradsky medium.

Coexistence of nitrifying, anammox and denitrifying bacteria in a sequencing batch reactor
Frontiers in Microbiology, 2014 Elevated nitrogen removal efficiencies from ammonium-rich wastewaters have been demonstrated by several applications, that combine nitritation and anammox processes. Denitrification will occur simultaneously when organic carbon is also present.

Une réévaluation de la methode d'incorporation de H14C03- pour mesurer la nitrification autotrophe et son application pour estimer des biomasses de bactéries nitrifiantes [PDF]
, 1998 Le processus de nitrification joue un rôle essentiel dans le cycle de l'azote dans les milieux aquatiques naturels. La mesure de l'activité nitrifiante est une étape obligée pour bien comprendre et quantifier les flux d'azote dans ces milieux. Ce travail

Increased salinity improves the thermotolerance of mesophilic nitrification [PDF]
, 2014 Nitrification is a well-studied and established process to treat ammonia in wastewater. Although thermophilic nitrification could avoid cooling costs for the treatment of warm wastewaters, applications above 40 A degrees C remain a significant challenge.

Toxic Response of Nitrobacter to Orange II and Direct Blue 71
Journal of Applied Sciences and Environmental Management, 2004 Tolerance of Nitrobacter to Orange II (C.L. 15510) and Direct Blue 71 (C.I. 34140) dyes was determined by total viable count. There was decrease in percentage log survival with increase in concentration of the toxicants and increase in exposure time ...
