“…Furthermore, peaks were generated at 2933 and 2853 cm −1 corresponding to aliphatic CH stretching. Similar observations for FTIR characterization are mentioned by Mate and Pathade while carrying out biodegradation of RR 195‐A with the Enterococcus faecalis strain YZ66 to analyze metabolites. They achieved nearly complete decolorization in 90 min at pH 5 under static anoxic condition.…”

The most widely used dyes for coloration of cotton textiles are from reactive class. However, the large amount of unfixed dye causes color in the wastewater, which is environmentally unacceptable. Decolorization of various commercially important reactive dyes in aqueous solutions was attempted by microbial treatment using the bacteria Proteus vulgaris and Proteus mirabilis, individually as well as in a consortium. Different parameters such as treatment temperature, pH, dye solution concentration, and the seed age of the bacteria were optimized to achieve maximum decolorization. Although both bacteria displayed good growth in a shake culture, the color removal was better in an anoxic static culture. The selected dyes were based on azo and anthraquinone chromophores and complete decolorization under optimized conditions could be achieved at a concentration of 30 mg/L. Good results were obtained also at dye concentrations of 60 and 90 mg/L.

“…[11,20,21], and RR 198 decolorized after 7 d with P. simplicissimum [7]. Waste material containing RR 195 showed 99.5% decolorization within 90 min using Enterococcus faecalis strain YZ66 [22]. In our own research with Aspergillus flavus, rapid degradation of over 90% occurred during the first 4 h, with color removal continuing for 24 h and ultimately reaching around 99%.…”

A B S T R A C TAmong all environmental contaminants, industrial dye is one of the major pollutants of soil, water, and air. There are different chemical, physical, and biological methods for removal of all types of synthetic media from the environment. One common method is to utilize microorganisms like yeast, fungi, or bacteria. In this study, we identified a soil-derived microorganism and evaluated its efficacy for removal of industrial dye from wastewater. First, a strain of fungus isolated from various samples of soil was defined via colonial identification and DNA sequencing. Second, the bioremoval activity of the defined fungus (Rhizopus oryzae) in treating the water-soluble monoazo dye, Reactive Red 198, in synthetic media was evaluated using high-performance liquid chromatography. The effects of varying factors in processing, including dye concentration, fungal volume, time, and pH were determined. Under optimal conditions, a dye removal rate of 96% was obtained.

“…Enterococcus sp. can grow on hexane, xylene, and degrade azodyes released through textile industry effluent (Mate and Pathade 2012). However, to use the bacterial isolates, we need to test the synergism of them with the plants, so both can coexist together.…”

Oil spillage sites primarily contain various types of hydrocarbons, such as linear chain, polycyclic, and aromatic compounds, posing several detrimental effects on plants. Results from our previous study showed an alteration of various metabolomic parameters, indirectly resulting in an observable decline of growth in the mung seedlings upon incubation with phenol, toluene, xylene, and hexane. This study evaluates the role of these compounds upon plant growth and focusses to mitigate the effect of the same, using some isolated plant synergistic bacteria. We isolated Proteus sp., Streptococcus sp., and Enterococcus sp., and tested the synergism of them in mung seedlings (Vigna radiata) by hydroponics. Treatment with the above-mentioned compounds significantly reduced the root and shoot length of the seedlings when compared to the control. The bacterial treatment helped in reducing the adversity due to the xenobiotic insult, by improving the root shoot length of the treated seedlings. Proteus sp. was found to be the most promising among other isolates. In another experiment, plasmid profiling of the bacterial isolates was done, yielding a band of 4.5 kb common for all, serving as a clue to be the most probable plasmid responsible for the degradation of the compounds. Results from this study clearly indicate that Proteus sp. can be explored further for its plant synergism and xenobiotic degradative capability to exploit its potential in oil spillage land reclamation and establishing vegetation.
