Bioremediation of produced waters has been widely investigated in the last decades. More recently, microalgae-based treatments have developed to produce biomass. The objective this study was determine, at lab scale, remediation efficiency three origin microorganisms: a consortium halotolerant and halophilic microalgae their associated bacteria, bacteria from liquid digestate, aromatic-degrading...

Abstract An increasing amount of industrial chemicals are being released into wastewater collection systems and indigenous microbial communities in treatment plants not always effective for their removal. In this work, extracellular polymeric substances (EPS) recovered from aerobic granular sludge (AGS) were used as a natural carrier to immobilize specific strain, Rhodococcus sp. FP1, able degr...

In this study the biodegradation of oil by hydrocarbon degrading Pseudomonas putida in the presence of a biosurfactant-producing bacterium was investigated. The co-culture of test organisms exhibited improved degradation capacities, in a reproducible fashion, in aqueous and soil matrix in comparison to the individual bacterium culture. Results indicate that the in situ biosurfactant production ...

Quantitative PCR (qPCR) was coupled with reverse transcription (RT) to analyze both gene copy numbers and transcripts of the 16S rRNA gene and three reductive dehalogenase (RDase) genes (tceA, vcrA, and bvcA) as biomarkers of "Dehalococcoides" spp. in the groundwater of a trichloroethene-dense nonaqueous-phase liquid site at Fort Lewis, WA, that was sequentially subjected to biostimulation and ...
