Control of Sulfide Production in High Salinity Bakken Shale Oil Reservoirs by Halophilic Bacteria Reducing Nitrate to Nitrite

open access: yesFrontiers in Microbiology, 2017
Microbial communities in shale oil fields are still poorly known. We obtained samples of injection, produced and facility waters from a Bakken shale oil field in Saskatchewan, Canada with a resident temperature of 60°C.

A two-compartment upflow pilot scale bioreactor system for microbial sulfate reduction control studies

open access: yesMethodsX, 2019
Souring in oil fields occurs mainly due to the activity of sulfate reducing bacteria (SRB). Most of the studies on SRB are performed using upflow packed-bed reactors that have a limitation to describe the region close to the injection wells in oil fields,

Mitigating Sulfidogenesis With Simultaneous Perchlorate and Nitrate Treatments

open access: yesFrontiers in Microbiology, 2018
Sulfide biogenesis (souring) in oil reservoirs is an extensive and costly problem. Nitrate is currently used as a souring inhibitor but often requires high concentrations and yields inconsistent results.

Mitigation potential of global ammonia emissions and related health impacts in the trade network

open access: yesNature Communications, 2021
Ammonia emissions from agricultural sources can cause severe health impacts. Here, the authors show that about 25% of global agricultural ammonia emissions in 2012 were related to international exported goods and caused 61 thousand PM2.5 related ...

Designing sour taste signal micro-controller simulator

open access: yesJournal of Fundamental and Applied Sciences, 2016
In this paper, empirical studies on taste cells and the results of potential changes related to sour taste are used, and by studying the messages transmitted by the nervous system and equivalent sample signal of this taste, mathematical equations related to these changes are obtained, and by designing a microcontroller circuit capable of creating ...

Efeito da aplicação de nitrato na redução biogênica de sulfeto sob diferentes concentrações iniciais de bactérias redutoras de nitrato e sulfato Effect of nitrate application on reduction of biogenic sulphide under different initial concentrations of nitrate and sulphate-reducing bacteria

open access: yesQuímica Nova, 2010
The effect of sodium nitrate application in the reduction of biogenic sulphide was evaluated through a 2k complete factorial design, using as variable response the production of sulfide at intervals of incubation of 7, 14 and 28 days.

Investigating the Etiology of Sour Knuckles in Postchilled Beef Carcasses

open access: yesMeat and Muscle Biology, 2020
Development of sourness in beef round muscle cuts, such as knuckles, has been a long-standing issue in the beef industry with little characterization.

Biotechnological Applications of Microbial (Per)chlorate Reduction

open access: yesMicroorganisms, 2017
While the microbial degradation of a chloroxyanion-based herbicide was first observed nearly ninety years ago, only recently have researchers elucidated the underlying mechanisms of perchlorate and chlorate [collectively, (per)chlorate] respiration ...

Neuromorphic Devices and Computing for Sensing, Memory, and Control

open access: yesAdvanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.
