New anodes consisting of zirconium-doped PbO2 coating, growth on titanium dioxide interlayer, were deposited on titanium substrates using spin coating method and have been tested for the removal of ampicillin, a β-lactam antibiotic, from water. Morphological, structural, and electrochemical properties of the prepared coatings were characterized by...
This study aimed to evaluate the impact of four biochar concentrations (0, 2, 5, and 8%) on single and interactive effects of salinity and drought stresses on the morphological, physiological, and photosynthetic parameters of faba bean plants. PCA analysis showed that plants displayed different behavior under non-stressed and stressed conditions. T...
In this study, lead removal from aqueous solutions using biochar derived from olive mill solid and liquid wastes has been investigated by applying batch experiments and geochemical modelling. The batch adsorption experiments included the assessment of several key parameters such as the contact time (kinetic), initial concentration (isotherm), pH, a...
During the last decade, biochars have been considered as attractive and eco-friendly materials with various applications including wastewater treatment, energy production and soil amendments. However, the important nitrogen losses during biochars production using the pyrolysis process have limited their potential use in agriculture as biofertilizer...
In this research work, an ecofriendly approach was adopted for the treatment of two abundant liquid and solid agricultural wastes generated by olive mill industry: olive mill wastewater (OMWW) and raw olive pomace (ROP). It consists, firstly of the impregnation of ROP by OMWW and the conversion of the resulting impregnated sample (IROP) into hydroc...
Protective bilayer composite coatings based on polyetherimide (PEI) containing ZnO or CuO particles were applied on mild steel (MS) by the sol-gel dip coating method and exposed to aggressive NaCl solutions. Scanning electron microscopy (SEM) analysis revealed the formation of homogenous coatings and X-ray diffraction (XRD) and energy dispersive sp...
Hybrid H3PMo12O40/polymer composites were proposed here for the simple photocatalytic decomposition of erythrosine B and rose Bengal because of their unwanted effect on the environmental microorganism. Interestingly, the composite exhibited efficient photocatalytic activity for the decomposition of dyes under both mild near UV irradiation and solar...
Olive mill wastes in the Mediterranean continue to be a management challenge due to the large volumes produced. Their recycling in agricultural systems may be improved, with multiple benefits for the environment and soil protection, while promoting the circular economy. Information on amounts and physicochemical properties of olive mill wastes will...
Characterization of the biofilm growing on stainless steel (SS) in untreated (UTUWW) and treated (TUWW) urban wastewaters was performed. In both media, the first phase of biofilm growth was aerobic, when the genera Caldimonas, Caulobacter, Terriglobus and Edaphobacter (iron oxidizing bacteria [IOB]) and the genera Bacillus, Sulfurimonas, Syntrophob...
The olive oil industry is an important economic sector in Mediterranean countries. However, oil production is unfortunately accompanied by the generation of huge amounts of olive mill solid wastes (OMSW) and olive mill wastewater (OMWW). In the present study, a strategy is proposed for converting these olive mill wastes into biochar through pyrolys...
Biochars produced from exhausted grape marc waste were considered a potential source for agriculture biofertilization. Results indicated that the biochar application did not show a significant effect on ryegrass fresh weight increase. The pyrolysis temperature influenced the fresh and dry matter yield since it interferes with phosphorus bioavailabi...
Olive mill wastes continue to be a management challenge due to the large volumes produced, particularly due to their toxicity and impacts on the environment. Thermal conversion through pyrolysis or hydrothermal carbonization techniques can detoxify wastes while conserving nutrient contents. In this work, we produced up-to-date data on olive mill wa...
Bacteria are able to construct biofilm adjacent to carbon steel surface and leading to the biocorrosion and metal deterioration. The impact of wasterwaters’ indigenious bacteria on biocorrosion of carbon steel was evaluated under different pH values (3,7 and 9), two chloride concentrations (0.5 g/L and 1.5 g/L), and for two wastewaters. In tannery...
Spain, Greece and Tunisia are among the largest worldwide producers of olive oil. Olive oil extraction technologies generally belong within three categories: the traditional extraction system, the three-phase extraction system, and the two-phase extraction system. The three-phase extraction system, while prohibited in Spain, represents about 70% an...
Microbiologically influenced corrosion (MIC) of bare and silane-TiO2 sol-gel coated stainless steel (SS) was studied in treated urban wastewater (TUWW). Combining the electrochemical impedance spectroscopy (EIS) and the scanning vibrating electrode technique (SVET) showed that SS surface colonization occurs, at earlier stages, by iron-oxidizing bac...
Olive mill wastes in the Mediterranean continue to be a management 17 challenge due to the large volumes produced. Their recycling in agricultural 18 systems may be improved, with multiple benefits for the environment, soil pro-19 tection, while promoting the circular economy. We obtained up-to-date data on 20 olive production and generation of was...
The biocorrosion mechanism of 304 L stainless steel (SS), in contact with untreated wastewater (UTWW) and treated wastewater (TWW) in terms of biofilm growth were monitored and evaluated using electrochemical experiments, scanning electron microscopy (SEM) examinations and microbiological analyses. Within UTWW, open circuit potential (E oc ) and ch...
Five isolates able to use dibenzothiophene (DBT) as a sole sulfur source with high rates were selected to investigate their potentialities as biocatalysts of biodesulfurization reactions. The desulfurizing activities of selected strains were investigated in growing and resting cell state. The biodegradation yields were considerably higher in restin...
Pentachlorophenol (PCP) is a toxic compound which is widely used as a wood preservative product and general biocide. It is persistent in the environment and has been classified as a persistent organic pollutant to be reclaimed in many countries. Fungal bioremediation is an emerging approach to rehabilitating areas fouled by recalcitrant xenobiotics...
We examined the biotransformation of benzothiazole derivatives (BTHs) by an axenic microbial culture. A Gram-negative bacterium, tentatively named as strain HKT554 and identified as Pseudomonas putida, was able to transform not only benzothiazole and 2-mercaptobenzothiazole but also 2-methylthiobenzothiazole, which was previously reported as the de...
Two lactic acid bacteria (LAB) were selected from 100 LAB isolated from various sea products to examine their use in Dicentrarchus labrax preservation. The isolates, tentatively named strain nr 3 and 7, were identified as Lactobacillus plantarum and L. pentosus, respectively. They showed antagonistic activity against psychrotroph, pathogenic, and c...
Microbial degradation of thiodiglycol (bis(2-hydroxyethyl)sulfide, TDG) with petroleum-desulfurizing soil bacteria was examined. Among the bacteria tested, several strains belonging to the genera Rhodococcus and Gordonia grew on TDG as the sole sulfur source. The selected strain Rhodococcus sp. strain T09, which was re-identified as R. jostii, show...
