“…Decolorization of dyes by bacterial strains was initially performed by azoreductase catalyzed anaerobic reduction or breakage of the azo bonds followed by aerobic or anaerobic degradation of the resulting aromatic amines by a mixed bacterial community (Singh et al., ; Sponza &Işık, 2005). Following are other biological methods used to treat textile effluents: Aerobic treatment— Reports on the use of bacterial degradation of azo dyes are very few, although it has been found that some organisms are able to reduce the presence of dyes.…”

The word “textile” means to weave and was taken from the Latin word “texere.” Nowadays, textiles not only fulfill humankind's basic necessity for clothing, they also allow individuals to make fashion statements. As one of the oldest industries, the textile industry occupies a unique place in India. It is responsible for 14% of the total industrial manufacture in India. However, the textile industry is also considered to be one of the biggest threats to the environment. Pretreatment, dyeing, printing, and finishing operations are among the various stages of the industrial textile manufacturing process. These fabrication operations not only utilize huge quantities of power and water, they also generate considerable amounts of waste. The textile industry utilizes a number of dyes, chemicals, and other materials to impart the required qualities to the fabrics. These operations produce a significant amount of effluents. The quality of effluents is such that they cannot be put to other uses, and they can create environmental problems if they are disposed of without appropriate treatment. This review discusses different textile processing stages, pollution problems associated with these stages, and their eco‐friendly alternatives. Textile wet processing is described in detail, as it is the key process in the industry and it also generates the greatest amount of pollutants in textile processing. The environmental impact of textile effluents is discussed, as textile effluents not only impose negative effects on the quality of water and soil, they also imperil plant and animal health. In this paper, various methods for treating textile effluents are described. Discussion of physical, chemical, biological, and advanced treatment technologies of effluent treatment are included in this paper.

BACKGROUND: The petrochemical industry wastewater contains many organic compounds that are difficult to degrade. The activated sludge system reinforced by bioaugmentation technology represents a more effective alternative to treat industrial wastewater. In this study, bioaugmented activated sludge water demonstrated high efficiency in removing five tested hydrocarbons.RESULTS: Optimized degradation rates were obtained upon inoculation of a continuous bioreactor system with degradative bacteria (Acinetobacter sp., Aeromonas sp., Arthrobacter nicotianae, Burkholderia cepacia, Chryseobacterium sp., Pseudomonas fluorescens, Micrococcus luteus and Raoultella planticola). The addition of a hydrocarbon mixture (terephthalic acid, acenaphthene, fluorene, anthracene, and pyrene) into the bioaugmented sludge resulted in degradation rates equivalent to 97.90%, 99.87%, 98.89%, 97.28%, and 94.55% respectively after 24-48 h incubation. Molecular biomonitoring was performed with real-time quantitative polymerase chain reaction (qPCR). According to the obtained results, the numbers of copy DNA of the degradative bacteria increased by 0.36-1.13 log at the end of the degradation process. The presence of some oxygenase genes (Nah, NidA, Pah Rhd Gr(+), Pah Rhd Gr(−) and C23O), that catabolize aromatic hydrocarbons in activated sludge, were detected by specific primers. CONCLUSION: Bioaugmentation represents a potent and eco-friendly approach that can effectively remove the drastic increase in the concentrations of aromatic hydrocarbons in industrial wastewaters. Molecular biomonitoring during degradation can be considered a rapid and an effective in situ method that quantifies the active microbial population in wastewater. The method provides beneficial information about the composition of microbial community and sustainability of the degradation process. Figure 3. The graphics reveal the alterations in the copy number of DNA of bacterial isolates in bioaugmented sludge during the three stages (n = 3, ± standard deviation). (a-c) The numbers of bacteria at the first, second and third stages and the copy number of DNA in the first, second and third stages, respectively. The copy number of DNA of all bacterial isolates have increased as the concentration of hydrocarbon increased. J Chem Technol Biotechnol 2020; 95: 52-62

“…As discussed in section 2.2 that the morphology of rhamnolipid aggregates is closely related to rhamnolipids concentration, pH, ionic strength and DOM, and the bioavailability of hydrocarbons may be different under different aqueous phase conditions. Moreover, the concentration of rhamnolipid, DOM, temperature, pH and ionic strength of the aqueous phase have a significant influence on degradation activity and transport of bacteria in soils (Liu, Zhong, et al, ; Singh et al, ; Zhong et al, ), which are of importance for successful bioremediation.…”

The objective of this review is to provide a comprehensive overview of the advances in the applications of rhamnolipids biosurfactants in soil and ground water remediation for removal of petroleum hydrocarbon and heavy metal contaminants. The properties of rhamnolipids associated with the contaminant removal, that is, solubilization, emulsification, dispersion, foaming, wetting, complexation, and the ability to modify bacterial cell surface properties, were reviewed in the first place. Then current remediation technologies with integration of rhamnolipid were summarized, and the effects and mechanisms for rhamnolipid to facilitate contaminant removal for these technologies were discussed. Finally rhamnolipid-based methods for remediation of the sites co-contaminated by petroleum hydrocarbons and heavy metals were presented and discussed. The review is expected to enhance our understanding on environmental aspects of rhamnolipid and provide some important information to guide the extending use of this fascinating chemical in remediation applications.
