“…Bacillus strains have previously been shown to be involved in the degradation of at least one of the DNT isomers [ 3 , 4 , 24 ] and to degrade other environmental pollutants. For example, the Bacillus consortium was successfully used for the biodegradation of phenol in wastewater [ 25 ], hydrocarbon in soil [ 26 ] and groundwater [ 27 ]. Weekly sampling starting prior to the incubation occurred over 6 weeks.…”

The dinitrotoluene isomers 2,4 and 2,6-dinitrotoluene (DNT) represent highly toxic, mutagenic, and carcinogenic compounds used in explosive manufacturing and in commercial production of polyurethane foam. Bioremediation, the use of microbes to degrade residual DNT in industry wastewaters, represents a promising, low cost and environmentally friendly alternative technology to landfilling. In the present study, the effect of different bioremediation strategies on the degradation of DNT in a microcosm-based study was evaluated. Biostimulation of the indigenous microbial community with sulphur phosphate (2.3 g/kg sludge) enhanced DNT transformation (82% transformation, from 300 g/L at Day 0 to 55 g/L in week 6) compared to natural attenuation over the same period at 25 °C. The indigenous microbial activity was found to be capable of transforming the contaminant, with around 70% transformation of DNT occurring over the microcosm study. 16S rDNA sequence analysis revealed that while the original bacterial community was dominated by Gammaproteobacteria (30%), the addition of sulphur phosphate significantly increased the abundance of Betaproteobacteria by the end of the biostimulation treatment, with the bacterial community dominated by Burkholderia (46%) followed by Rhodanobacter, Acidovorax and Pseudomonas. In summary, the results suggest biostimulation as a treatment choice for the remediation of dinitrotoluenes and explosives waste.

“…The effect of air-water backwashing effects was evaluated in a pilot-scale biological aerated filter (BAF) treating petrochemical wastewater . The total sludge produced in the backwashing effluent increased with the increase in water-backwashing intensity, while the total specific oxygen uptake rate ( Bioremediation of phenol-contaminated industrial wastewater using a bacterial consortium was investigated to establish a suitable methodology specifically for the translation of a laboratory-scale system to an industrial scale (Poi et al, 2017). The microbial consortia also reduced the toxicity of the wastewater while degrading the phenol and lowering the wastewater COD.…”

Petrochemical and oil & gas industries are crucial for global economy while great attention is needed for the related contamination and its impact on the environment. Papers reviewed herein represent the recent research and development on petrochemical wastewater and produced water from oil & gas industry, published in 2017 and beginning of 2018 globally. In the petrochemical wastewater, progresses were made in characterization, physicochemical treatment and biological treatment. In the oil & gas produced water, efforts were made on the characterization, the environmental impact and treatment options.

“…Phenol, however, being an inhibitory substrate at relatively low concentrations, poses a serious challenge for biochemical treatment processes (Christen et al 2012 ; Felföldi et al 2020 ). To overcome the challenge of phenol inhibition, bioprocesses aiming the degradation of phenol and phenolic compounds received much research attention in the last decades (Pradeep et al 2015 ; Poi et al 2017 ).…”

The objective of this study was to establish and to mathematically describe the phenol degrading properties of a new Acinetobacter towneri CFII-87 strain, isolated from a bioreactor treating landfill leachate. For this purpose, the biokinetic parameters of phenol biodegradation at various initial phenol concentrations of the A. towneri CFII-87 strain have been experimentally measured, and four different mathematical inhibition models (Haldane, Yano, Aiba and Edwards models) have been used to simulate the substrate-inhibited phenol degradation process. The results of the batch biodegradation experiments show that the new A. towneri CFII-87 strain grows on and metabolizes phenol up to 1000 mg/L concentration, manifests significant substrate inhibition and lag time only at concentrations above 800 mg/L phenol, and has a maximum growth rate at 300 mg/L initial phenol concentration. The comparison of the model predictions with the experimental phenol and biomass data revealed that the Haldane, Aiba and Edwards models can be used with success to describe the phenol biodegradation process by A. towneri CFII-87, while the Yano model, especially at higher initial phenol concentrations, fails to describe the process. The best performing inhibition model was the Edwards model, presenting correlation coefficients of R2 > 0.98 and modelling efficiency of ME > 0.94 for the prediction of biomass and phenol concentrations on the validation datasets. The calculated biokinetic model parameters place this new strain among the bacteria with the highest tolerance towards phenol. The results suggest that the A. towneri CFII-87 strain can potentially be used in the treatment of phenolic wastewaters.
