Impact on nitrifiers of full-scale bioaugmentation [PDF]

Water Science and Technology, 2017
AbstractNitrifiers are the slowest growing bacteria used in conventional biological wastewater treatment. Furthermore, their growth rate is seriously hampered by low temperature. As a result, the volume needed for nitrification dominates the volume of the biological reactors at a wastewater treatment plant.

Augmentation of Granular Anaerobic Sludge with Algalytic Bacteria Enhances Methane Production from Microalgal Biomass

Fermentation, 2019
The efficiency of anaerobic digestion relies upon activity of the inoculum converting organic substrate into biogas. Often, metabolic capacity of the inoculum needs to be augmented with new capabilities to accommodate changes in the substrate feed ...

Systems‐Level Optimization of Hybrid Produced Water Treatment Systems for Sustainable Oil and Gas Production: A Review of Current Technologies

Global Challenges, Volume 10, Issue 2, February 2026.
ABSTRACT Produced water (PW) is the largest and most complex waste stream generated during oil and gas production, posing significant environmental, operational, and regulatory challenges due to its high salinity, dispersed hydrocarbons, toxic organics, heavy metals, and naturally occurring radioactive materials. Although numerous studies have reviewed

Effect of bioaugmentation on digestate metal concentrations in anaerobic digestion of sewage sludge.

PLoS ONE, 2020
This study examined the influence of bioaugmentation on metal concentrations (aluminum, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel and zinc) in anaerobically digested sewage sludge.

Bioaugmentation for Improved Recovery of Anaerobic Digesters After Toxicant Exposure [PDF]

, 2010
Bioaugmentation was investigated as a method to decrease the recovery period of anaerobic digesters exposed to a transient toxic event. Two sets of laboratory-scale digesters (SRT = 10 days, OLR = 2 g COD/L-day), started with inoculum from a digester ...

Methane production from oleate : assessing the bioaugmentation potential of Syntrophomonas zehnderi [PDF]

, 2010
The potential for improving long-chain fatty acids (LCFA) conversion to methane was evaluated by bioaugmenting a non-acclimated anaerobic granular sludge with Syntrophomonas zehnderi.

A combination of microbial electrolysis cells and bioaugmentation can effectively treat synthetic wastewater containing polycyclic aromatic hydrocarbon

Water Science and Technology
The anaerobic biodegradation of polycyclic aromatic hydrocarbons (PAHs) is challenging due to its toxic effect on the microbes. Microbial electrolysis cells (MECs), with their excellent characteristics of anodic and cathodic biofilms, can be a viable way

Trehalose promotes Rhodococcus sp. strain YYL colonization in activated sludge under tetrahydrofuran (THF) stress

Frontiers in Microbiology, 2015
Few studies have focused on the role of compatible solutes in changing the microbial community structure in bioaugmentation systems. In this study, we investigated the influence of trehalose as a biostimulant on the microbial community in THF-treated ...

Ecological Response in the Integrated Process of Biostimulation and Bioaugmentation of Diesel-Contaminated Soil

Applied Sciences, 2021
The study applied microbial molecular biological techniques to show that 2.5% to 3.0% (w/w) of diesel in the soil reduced the types and number of bacteria in the soil and destroyed the microbial communities responsible for the nitrogen cycle.

Bioremediation of PAHs-contaminated soil through composting : influence of bioaugmentation and biostimulation on the contaminants biodegradation [PDF]

, 2011
The degradation of several polycyclic aromatic hydrocarbons (PAHs) in soil through composting was investigated. The selected PAHs included: fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, and chrysene, with concentrations ...
