Isolation and characterization of a Rhodococcus strain able to degrade 2-fluoro...

A pure bacterial culture able to utilize 2- fluorophenol (2-FP) as sole carbon and energy source was isolated by selective enrichment from sediments collected from a contaminated site in Northern Portugal. 16S rRNA gene analysis showed that the organism (strain FP1) belongs to the genus Rhodococcus. When grown aerobically on 2-FP, growth kinetics of strain FP1 followed the Luong model. An inhibitory effect of ...

Biodegradation of the fluorinated antibiotic moxifloxacin

2-Fluorophenol degradation by aerobic granular sludge in a sequencing batch rea...

Aerobic granular sludge is extremely promising for the treatment of effluents containing toxic compounds, and it can economically compete with conventional activated sludge systems. A laboratory scale granular sequencing batch reactor (SBR) was established and operated during 444 days for the treatment of an aqueous stream containing a toxic compound, 2-fluorophenol (2-FP), in successive phases. Initially durin...

Bioaugmentation of a rotating biological contactor for degradation of 2-fluorop...

The performance of a laboratory scale rotating biological contactor (RBC) towards shock loadings of 2-fluorophenol (2-FP) was investigated. During a period of ca. 2 months organic shock loadings of 25 mg L 1 of 2-FP were applied to the RBC. As no biodegradation of 2-FP was observed, bioaugmentation of the RBC with a 2-FP degrading strain was carried out and, along ca. 6 months, organic shock loadings within a r...

Studies on the biodegradation of fluoroanilines by a single microorganism

Aromatic amines are considered important environmental pollutants due to their toxic and recalcitrant properties. The widespread use of these compounds in the industry and agriculture has led to their release to soils and waters. Microbial degradation has been found to be the major mechanism to avoid the accumulation of these pollutants in the environment. Literature studies on the biodegradation of halogenate...

Genetic, phenotypic and functional variation within a Glomus geosporum isolate ...

Genetic, phenotypic and functional variation in a Glomus geosporum isolate obtained from a highly alkaline anthropogenic sediment was investigated. Two cultivation lineages of G. geosporum (BEG199 and BEG211) were created by sub-culturing with or without the stress of the sediment. Genetic variation was assessed on spores from both cultivation lineages in the large sub-unit rRNA gene D2 region using PCR-single ...

Degradation of fluoroanilines by the wild strain Labrys portucalensis

Aromatic amine compounds, many of them with halogenated substituents, constitute a major class of environmental pollutants that have been released into soil and water due to extensive use in industries and agriculture. Biodegradation has been found to be a major route for the removal of this kind of toxic and recalcitrant pollutants from the environment. Whereas the degradation of mono- and dichlorinated anilin...
