In this paper, the effect of NaCl and Na2SO4 on the biodecolourization of reactive brilliant red K-2BP by a Halomonas sp. GYW (EF188281) was investigated in details. The decolourisation efficiency and the oxidation-reduction potential (ORP) change were explored during the decolourization process. The results from sequencing batch tests showed that Na2SO4 influenced the decolourization efficienc...

halophilic and halotolerant microorganisms are good candidates for decolorization of azo dyeswhich are routinely used in the dyeing process in textile industries. in this paper, theoptimization of biological decolorization of synthetic dye solutions containing remazol black bby the previously isolated halophilic bacterium halomonas sp. d2 is investigated. in a primaryinvestigation using a one-f...

This paper presents the characterization of the microbial community responsible for the in-situ bioremediation of hexachlorocyclohexane (HCH). Microbial community structure and function was analyzed using 16S rRNA amplicon and shotgun metagenomic sequencing methods for three sets of soil samples. The three samples were collected from a HCH-dumpsite (450 mg HCH/g soil) and comprised of a HCH/soi...

Light scattering and chemical cross-linking analyses of nucleoside diphosphate kinase (NDK) from moderate halophile, Halomonas sp. 593 (HaNDK), unambiguously demonstrated that this enzyme formed a dimeric structure, in contrast to the Pseudomonas NDK (PaNDK), a nonhalophilic counterpart, and other NDKs from Gram-negative bacteria, which all formed a tetrameric structure. Comparison of HaNDK and...

In the present work, ability of different sodium-based salts like Na2CO3, Na2HPO4, Na2SO4 and Na2SO3 to salt out aqueous solutions two biodegradable non-ionic surfactants (Tergitol 15S7 Tergitol 15S9) has been demonstrated. We have empirically characterized immiscibility regions models Merchuk Othmer-Tobias equations were employed for binodal tie-line data, respectively. The effect phase formin...
