“…The aerobic bacterial consortium consisting with four bacterial strains Klebsiella pneumoniae (KU726953), Salmonella enterica (KU726954), Enterobacter aerogenes (KU726955), and Enterobacter cloacae (KU726957) isolated from distillery sludge sample in our laboratory to degrade synthetic Maillard reaction products (MRPs) was used in this study (Kumar and Chandra 2018). The seed culture was prepared for degradation by inoculating the pure bacterial colonies in broth medium and incubated for 24 h in continuous shaking condition (120 rpm) in 250 mL Erlenmeyer flask containing sterilized 100 mL mineral salt medium supplemented with K 2 HPO 4 (0.1%), MgSO 4 •7H 2 O (0.05), and molassesmelanoidins (1000 mg L −1 ) and incubated at 35 ± 1 °C and 130 rpm.…”

The extracted sugarcane molasses-melanoidins showed the presence of Mn (8.20), Cr (2.97), Zn (16.61), Cu (2.55), Fe (373.95), Pb (2.59), and Ni (4.18 mg L) along with mixture of other organic compounds which have endocrine-disrupting chemicals (EDCs) properties. A consortium of aerobic bacteria comprising (KU321273), (KU726954), (KU726955), and (KU726957) showed the optimum decolourisation of molasses-melanoidins up to 81% through co-metabolism in the presence of glucose (1.0%) and peptone (0.2%) as a carbon and nitrogen source, respectively. The absorption spectrum scanning by UV-visible spectrophotometer between 200 and 700 nm revealed reductions of absorption spectrum of organic compounds present in bacterial degraded sample of melanoidins in range of 200-450 nm compared to control. The degradation and decolourisation of melanoidins by bacterial consortium was noted by induction of manganese peroxidase and laccase activities in sample supernatant. Furthermore, the TLC and HPLC analysis of bacterial decolourised melanoidins also showed degradation and reduction of absorption peak at (295 nm), respectively. Furthermore, FT-IR and GC-MS analysis also showed the change of functional group and disappearance of ion peaks. This indicated the degradation and depolymerisation of melanoidins and cleavage of C=C, C=O and C≡N conjugated bonds which resulted in reduction of colour. The metabolic analysis also showed the disappearance of some organic compounds and generation of new metabolites. Furthermore, the seed germination test using L. showed toxicity reduction in decolourized effluent.

The function of ligninolytic enzymes was observed in decolorization and showed a high content of manganese peroxidase and laccase [ 64 ]. E. cancerogenus and E. ludwigii were isolated from petroleum-contaminated soil and animal manure samples in Turkey.…”

Wastewater released from textile and dye-based industries is one of the major concerns for human and aquatic beings. Biological decolorization using ligninolytic bacteria has been considered as an effective and alternative approach for the treatment of dyeing wastewater. This study aimed to assess the isolation, characterization and application of soil bacteria isolated from mangrove wetlands in Thailand. Four active bacteria were genetically identified and designated as Klebsiella pneumoniae strain RY10302, Enterobacter sp. strain RY10402, Enterobacter sp. strain RY11902 and Enterobacter sp. strain RY11903. They were observed for ligninolytic activity and decolorization of nine reactive dyes under experimental conditions. All bacteria exhibited strong decolorization efficiency within 72 h of incubation at 0.01% (w/v) of reactive dyes. The decolorization percentage varied from 20% (C.I. Reactive Red 195 decolorized by K. pneumoniae strain RY10302) to 92% (C.I. Reactive Blue 194 decolorized by Enterobacter sp. strain RY11902) in the case of bacterial monoculture, whereas the decolorization percentage for a mixed culture of four bacteria varied from 58% (C.I. Reactive Blue 19) to 94% (C.I. Reactive Black 1). These findings confer the possibility of using these bacteria for the biological decolorization of dyeing wastewater.

a b s t r a c tIllegal dumping of phenol-concentrated industrial wastewater in a residential area poses serious health risks to the community in Thailand. Thus, a low-cost and easily implementable treatment technique that the affected community can perform is greatly beneficial. Here, we evaluated the enhanced phenol-degradation kinetics using a rhizomicrobial-augmented mature vetiver root system on a floating platform (with and without aeration) in comparison to a previously published study of a young vetiver root system. The mature vetiver root was covered with a biofilm of phenol-degrading rhizomicrobes including bacteria (Enterobacter spp., Pseudomonas spp., Rhodococcus spp., and Acinetobacter spp.) and fungi (Candida spp., Rhizopus spp., Aspergillus spp., and Fusarium spp.). Phenol (500 mg L -1 ) was degraded to 1 mg L -1 in 249 h using rhizomicrobial-augmented mature vetiver with aeration. Using young vetiver plantlets with aeration, this occurred in 675 h, and using rhizomicrobial-augmented mature vetiver without aeration, this occurred in 766 h. The findings suggest that, in addition to augmented rhizomicrobes, vetiver maturity and aeration substantially contribute to the enhancement. The vetiver maturity increased the root biomass, which releases more peroxidase for accelerating phenol transformation, and enhanced the superoxide dismutase activity, which decreases the side effects of phenol detoxification. Aeration enhanced the peroxidase and superoxide dismutase activity in the vetiver and augmented rhizomicrobes to accelerate the phenol polymerization to non-toxic by-products.
