“…Many studies have shown that the different species of Pseudomonas are able to degrade the synthetic dyes mainly azo dye in the liquid medium and have been used for the treatment of textile e uent [23]. Moreover, many sulphonated aromatic compounds are utilized by dye manufacturing industries as primary materials to produce dyes and many of them are released as byproducts in the e uents coming from textile industries [10]. Besides, the textile industry is widely using Na 2 SO 4 in dying process and sulphuric acid for maintaining the pH within the wastewater treatment plants.…”

“…The wastewater generated from the small scale industries contains the complex mixture of the manufacturing of textile dyes, paints, chemicals, solvents, and textile released wastewater [10]. Hence, the microbial community present in such ecosystem are exposed to diverse array of substrates and are responsible for the degradation capacity of these molecules in the target niche.…”

Background: Understanding microbial and functional diversity from different stages of common effluent treatment plant (CETP) plays an important role to enhance the treatment performs of wastewater systems. However, unraveling microbial interactions as well as utilization of substrate involved in complex microbial communities is a challenging task. Hence, we demonstrate an integrated approach of shotgun metagenomics and whole genome sequencing to identify the microbial diversity and genes involved in degradation of benzoate, 1,2-dichloroethane and phenylalanine metabolism and degradation pathways from CETP microbiome.Results: The taxonomy profile was annotated using the Ribosomal Database Project (RDP) database in the MG-RAST server. The results showed that, bacteria accounted for 98.46% was the most abundant domain, followed by Eukaryota (0.10%) and Archea 0.02%. At Phylum level, Proteobacteria (28.8%) were dominant, followed by Bacteroidetes (16.1%), Firmicutes (11.7%) and Fusobacteria (6.9%). The most dominated species were Klebsiella pneumoniae, Wolinella succinogenes, Pseudomonas stutzeri, Desulfovibris vulgaris, Clostridium sticklandii, and Escherichia coli. The Clusters of Orthologous Groups (COGs) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, revealed the presence of the genes responsible for the metabolism and degradation of aromatic compounds. This information was validated with the whole genome analysis of the bacteria isolated from the CETP.Conclusion: The two type of integrated meta omics analyses revealed that the metabolic and degradation capability at both community wide and individual bacterial levels. In addition, we demonstrated that microbial diversity changes with the treatment process in which inlet of CETP effluent shows higher dominancy of Proteobacteria whereas in textile industry outlet the high abundance of Firmicutes was observed. We foresee this approach would contribute in designing the bioremediation strategies for the industrial treatment process.

SummarySulphonated anthraquinones are resistant to biodegradation and are, therefore, not eliminated by traditional wastewater treatment plants; this leads to their accumulation in fresh water. To develop new technologies, e.g. phytoremediation, for treatment of such pollutants, a powerful technique is needed for their rapid and inexpensive detection and quantification in any kind of sample. For this purpose capillary electrophoresis seems to be a very promising technique.An efficient, rapid, and inexpensive method has been developed for analysis of five sulphonated anthraquinones, in the 50-950 IxM range, with a simple borate buffer. The procedure has been shown to be efficient for all the samples tested, i.e. pure standard solutions, hydroponic media in which plants, bacteria, and algae had grown for 6 weeks, and even plant extracts. This last result is consistent with the idea that phytoremediation could be used as an alternative means ofwastewater treatment for these recalcitrant compounds.

“…Synthetic surfactants have many applications and high consumption rates in different fields including household cleaning detergents, personal care products, textiles and pesticide formulations, etc. [3,[9][10][11]. Previous researches documented that the engineered surfactants were toxic to microorganisms, plants (e.g., Sorghm bicolour, Helianthuus annuus, Phaseolus aureus, etc.…”

Surface activity of humic acid (HA) and its six sub-fractions isolated from forest soil were characterized by surface tension measurements, dynamic light scattering, and laser doppler electrophoresis. The surface tension of HA sub-fractions decreased from 72.4 mN·m-1 to 36.8 mN·m-1 with the increasing concentration from 0 to 20000 mg·L-1. The critical micelle concentration (CMC) of HA and its sub-fractions ranged from 216 to 1024 mg·L-1 with the multiple linear regression equation of CMC = 18896–6.9×C–296×alkyl-C–331×aromatic-C–17019×H/C+4054×HB/HI (p &lt; 0.05). The Z-average particle size ranges from 108.2 nm to 186.9 nm. The maximum particle size was 5000 nm after filtered with a membrane of 0.45 μm, indicating HA and its sub-fractions progressed self-assembly during 2000 mg·L-1, pH = 6.86. The number-base particle size distribution of HA sub-fractions was identified as four peaks by Gaussian model, and the aggregate sizes were mainly in six clusters including 2 ± 1 nm, 5 ± 2 nm, 10 ± 3 nm, 21 ± 8 nm, 40 ± 10 nm, and &gt; 50 nm indicating multiple aggregations of different particle sizes in the HA fractions solution.
