Transport of EDTA into cells of the EDTA-degrading bacterial strain DSM 9103

Purification and characterization of EDTA monooxygenase from the EDTA-degrading bacterium BNC1.

The synthetic chelating agent EDTA can mobilize radionuclides and heavy metals in the environment. Biodegradation of EDTA should reduce this mobilization. Although several bacteria have been reported to mineralize EDTA, little is known about the biochemistry of EDTA degradation. Understanding the biochemistry will facilitate the removal of EDTA from the environment. EDTA-degrading activities we...

Modeling the transport of metals with rate-limited EDTA-promoted extraction and dissolution during EDTA-flushing of copper-contaminated soils.

EDTA-flushing of artificially contaminated soils enhanced Cu extraction but also induced mineral dissolution simultaneously. The mobilization and transport of these metal-EDTA complexes was investigated with column experiments. A quantitative transport model was proposed for simulating the experimental breakthrough curves of Cu, Fe, Al, and Ca. The rate-limited EDTA-promoted extraction and diss...

Effectiveness of EDTA and EDTA-T brushing on the removal of root surface smear layer.

The purpose of this study was to compare the removal of root surface smear layer following active application of EDTA gel and EDTA-T (texapon) gel in different concentrations (5%, 10%, 15%, 20% and 24%), using scanning electron microscopy. A total of 220 dentin blocks obtained from the root surfaces of extracted teeth were divided into 3 groups: Group I - (control) application of saline solutio...

First Insights into the Genome of the N-Methylhydantoin-Degrading Clostridium sp. Strain FS41 (DSM 6877)

Clostridium sp. strain FS41 (DSM 6877) is a strictly anaerobic and Gram-positive spindle-shaped rod. This spore-forming bacterium is able to degrade N-methylhydantoin, with N-carbamoylsarcosine and sarcosine as intermediates. The genome consists of one replicon (6.28 Mb) and harbors 5,735 predicted protein-coding genes.
