“…Studies conducted with bacteria revealed their great potential for hazardous contaminants biodegradation and/or removal. These microorganisms have the ability to adjust to environmental changes due to the selective character of their cellular membrane and to the release of bio-products that lower the surface tension and eventually reduce the concentration of toxic compounds present inside the cells by the use of efflux pumps [43]. The structural polymers present in the cell wall provide functional groups such as carboxyl, phosphoryl and amino groups responsible for the cell membrane reactivity and for the ability of bacteria to degrade, fix and/or entrap pollutants from aquatic environment [44].…”

This work addresses the treatment of a complex industrial effluent containing high concentrations of metals and spiked with two organic solvents (diethylketone -DEK, and methyl ethyl ketone -MEK) using an eco-friendly approach. The treatment system herein proposed consists of a bio-barrier that combines the adsorption capacity of sepiolite with the properties of a Streptococcus equisimilis biofilm with proven ability in the degradation and bioremoval of a wide range of pollutants.Results from the open-systems experiments conducted with raw sepiolite exposed to a binary mixture of DEK and MEK revealed the preference of the sorbent towards DEK. The results from the biodegradation experiments also revealed the preference of S. equisimilis to degrade/bioremove DEK over MEK independently of their initial concentration (100 mg/L to 3200 mg/L). Bioremoval percentages higher than 95% were reached for all the concentrations of DEK tested. The lab-scale experiments conducted in open-system with sepiolite and sepiolite covered with biofilm, and the pilot-scale experiment conducted in closed-loop, revealed similar performances on the rehabilitation of an industrial effluent containing heavy metals and additionally spiked with DEK and MEK. Regarding the selectivity towards the different pollutants, Cu was preferentially removed over Cr and Ni, and DEK over MEK. The presence of the biofilm allowed an improvement on the removal of heavy metals, particularly Cr, besides preventing the leaching of Al, Fe, and Mg from the sepiolite structure, an extremely important advantage in comparison to the system without biofilm. EDS analyses performed in sepiolite samples revealed the presence of several metals (Cr, Cu and Ni), proving thus the occurrence of sorption processes by sepiolite and by sepiolite covered by biofilm. The breakthrough data obtained in the open-systems were properly described by the Dose Response and the Yoon and Nelson mathematical models. More research work needs to be performed with complex industrial effluents aiming the optimization of the treatment systems to be applied in real context scenarios.

“…The examination of microbial activity was demonstrated the ability of the HAT compound to inhibit bacterial growth in kerosene facilities, especially in tanks that can corroded due to the high growth rate of certain types of bacteria in kerosene medium . The inhibition zone of antibacterial activity of HAT compound was determined using the disk diffusion method with different concentrations (100‐500 ppm) against four types of bacteria, which have the capability to degrading aromatic and aliphatic hydrocarbons such as gram‐positive bacteria ( Staphylococcus aureus and Streptococcus spp .)…”

A triazole inhibitor, 3,5-di(4-hydroxyphenyl)-4-amino-1,2,4-triazole (HAT), was investigated as an anticorrosion material for carbon steel in Iraqi kerosene tanks using Tafel polarization method at (303, 313, 323, and 333 K) and (100-500 ppm) in kerosene medium. The results showed that the highest inhibition efficiency was obtained at 86.74% in 100 ppm and 333 K. The studied thermodynamic parameters show that the adsorption isotherm of the HAT inhibitor on the steel surface was identical to Langmuir isotherm. The polarization behavior revealed that this inhibitor acts as a mixed-type inhibitor, the corrosion inhibition data have been measured and discussed in details to predict the performance of the inhibitor. The morphology of the inhibited surfaces was characterized using scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) and an atomic force microscope (AFM). Furthermore, the Fourier transform infrared (FT-IR) technique was used to show the interaction between HAT and the steel surface. Also, the antimicrobial activity of HAT inhibitor against some types of corrosive bacteria was examined. In addition, quantum chemical parameters were calculated by density functional theory to reveal the active centers of the inhibitor and clarify the correlation of molecular structure of the inhibitor and its efficiency of the inhibition.

Contamination of potentially toxic metals poses threats to living organisms due to prolonged existence in an ecosystem. The effects of toxic metals on soil microbes have broadly been reported but the study on interactions among soil micro‐ and macro‐organisms under metal stress needs to be elaborated. In current study, the immobilization of lead (Pb) is investigated by using five resistant microbial strains; (2) Bacillus cereus, (1) Bacillus subtilis, (1) Brevundimonas naejangsanensis, and (1) fungal strain Fusarium equiseti isolated from contaminated soil of Hattar, Pakistan. Bacterial and fungal strains and their consortia are tested in the presence/absence of nematodes for Pb immobilization in a medium containing 250 mg L−1 Pb. Single bacterial strains immobilize Pb up to 72%, while in the presence of nematodes, bacterial immobilization potential decreases. An increased Pb immobilization up to 185 mg L−1 is found when bacterial and fungal consortia are inoculated with nematodes. The maximum 80% Pb immobilization is found in bacterial–bacterial combinations with nematodes. This study, reveals that inoculation of bacterial–bacterial consortia in the presence of nematodes enhanced bacterial growth via feeding resulting in higher Pb immobilization. These resistant microbial strains can thus be used to treat contaminated sites for better ecosystem functioning.
