Nitrogen removal intensification of aerobic granular sludge through bioaugmentation with "heterotrophic nitrification-aerobic denitrification" consortium during petroleum wastewater treatment.

Bioresource Technology, 2022
The bioaugmentation potential of aerobic granular sludge (AGS) was investigated using heterotrophic nitrification-aerobic denitrification (HN-AD) bacterial consortium to improve nitrogen removal during petroleum wastewater treatment.

Ecological study of a bioaugmentation failure

Environmental Microbiology, 2000
A nitrifying sequencing batch reactor was inoculated twice with the aerobic denitrifying bacterium Microvirgula aerodenitrificans and fed with acetate. No improvement was obtained on nitrogen removal. The second more massive inoculation was even followed by a nitrification breakdown, while at

Bioaugmentation of Methanosarcina thermophila grown on biochar particles during semi-continuous thermophilic food waste anaerobic digestion under two different bioaugmentation regimes.

Bioresource Technology, 2022
This study presents the effect of bioaugmentation of thermophilic anaerobic digestion of food waste with Methanosarcina thermophila grown on a wood-derived biochar. Two different supplementation regimes were tested, namely a single bioaugmentation (SBABC)

Actinobacteria bioaugmentation and substrate evaluation for biobeds useful for the treatment of atrazine residues in agricultural fields.

Journal of Environmental Management, 2022
Biopurification systems (BPS) or biobeds are bioprophylaxis systems to prevent pesticide point-source contamination, whose efficiency relies mostly on the pesticide removal capacity of the biomixture, the majority component of a BPS.

Bioaugmentation for enhancing biological wastewater treatment

Biotechnology Advances, 1992
The literature on bioaugmentation products has been reviewed. Their manufacture and method of use is explained. The various applications are listed and the independent investigations, as opposed to manufacturers accounts, at laboratory and full scale are reviewed. The economics and kinetic modelling are also discussed.

Bioaugmentation of oil-contaminated soils

АгроЭкоИнфо, 2023
In a field experiment, the high efficiency of the in situ bioaugmentation method was demonstrated using three biological products (Putidoil, Arkoil and Multibak Asset) to clean up the territory in the Volgograd region 6 years after an emergency oil spill.

Bioaugmentation of Azo Dyes

2010
Biodegradation is a cost-effective method to remove the residues of azo dyes prior to their discharge in wastewater streams from dye product industries. The efficacy of this treatment method is highly dependent on establishing an effective degrader community and maintaining environmental conditions that support the growth and activity of the degrader ...

Bioaugmentation for Groundwater Remediation

2010
Abstract : The application of bioaugmentation technology has the potential to reduce both the time and cost associated with remediating groundwater contaminated with chlorinated volatile organic compounds (CVOCs), and it has become widely used as an in situ treatment alternative. The primary goals of this field demonstration were to evaluate the amount

Effect of compost amendment and bioaugmentation on PAH degradation and microbial community shifting in petroleum-contaminated soil.

Chemosphere, 2020
Efficient degradation of polycyclic aromatic hydrocarbons (PAHs) in a petroleum-contaminated soil was challenging which requires ample PAH-degrading flora and nutrients.

Bioaugmentation for nitrification at cold temperatures

Water Research, 2004
Bioaugmentation of nitrifying bacteria for short solids retention time (short-SRT) nitrification is an attractive alternative for wastewater treatment plants in cold climates or for those in the process of upgrading to include nitrification. One possible source of ammonia for the production of nitrifying bacteria is the liquor generated during the ...
