“…There are a lot of reports which confirm that bacteria from genera Pseudomonas have also the ability to degrade efficiently the wide spectrum of others complex xenobiotics, for example, PAHs, pesticides, PCBs (Imam et al 2019;Ramadass et al 2018;Salimizadeh et al 2018;Tandlich et al 2001;Zheng et al 2018). Such properties make these bacteria the promising candidates for use at the various cleaning technologies.…”

Synthetic dyes, generally resistant, toxic and carcinogenic presents a substantial risk to the environment and health of human. The present study was aimed to decolourize a dye mixture (Evans blue and brilliant green) by selected bacterial strains cultivated at different growth conditions (e.g. unmodified, correction of pH value and supplementation with nutrients). The bacterial strains used as pure and mixed cultures include facultative anaerobes Aeromonas hydrophila (Abs37), Citrobacter sp. (Cbs50) and obligatory aerobe Pseudomonas putida (Pzr3). The efficiency of removal of all successive doses of dye mixture (4-5 doses, total load 170-200 mg/l) was tested in static conditions in fedbatch bioreactors. The modification of bacteria growth conditions influenced on decolourization efficiency: most advantageous was pH value correction combined with nutrient supplementation then pH correction alone and nutrient supplementation (final removal results 95.6-100%, 92.9-100% and 89.1-97.2%, respectively). The mixed bacterial cultures removed the total load of dyes with higher efficiency than pure strains (final removal 95.2-100% and 84.0-98.2%, respectively). The best results were obtained for the mixture of facultative anaerobe Citrobacter sp. and obligatory aerobe Pseudomonas putida which removed the highest load of dye mixture (200 mg/l introduced at five doses) in the shortest time (288 h), while the others pure and mixed cultures needed 425-529 h for removal four doses of dye mixture (total load 170 mg/l). The zoo-and phytotoxicity decreased after these processes (from V class of toxicity (extremely toxic) even to II class (low toxicity)). The main mechanisms of decolourization was biotransformation/biodegradation, supported by sorption.

“…ey are made up entirely of carbon and hydrogen atoms and serve as the foundation for crude oil, natural gas, and coal, providing a significant proportion of the world's energy. Hydrocarbons are classified as saturates (branched and straight-chained), aromatic (mono and polycyclic), resins (pyridines, quinolines, carbazoles, sulfoxides, and amides), and asphaltenes (phenols, fatty acids, ketones, esters, and porphyrins) [8,14,15]. Hydrocarbons and their derivatives were intentionally or accidentally discharged into the environment, mainly to the soil and oceans, and principally existed in three physical states, that is, solid, liquid, or gaseous [16].…”

“…us, the redox potentials show oxidizing or reducing conditions, provide an indication of the relative dominance of the electron acceptor (oxygen, nitrate, sulfate, iron (III), manganese, chlorate, perchlorates, etc.) [8,51,83], and require an energy source (electron donor) and nutrients for bioremediation processes. For aerobic conditions, oxygen does not only act as a final electron acceptor but is also important to enzymatic activation of aromatic hydrocarbon as mono or dioxygenases.…”

Studies specified that microbial bioremediation (the use of microorganisms: bacteria, fungi, and microalgae) is the most efficient to transform pollutants into less toxic and less mobile form or to mineralize hydrocarbon contaminants into H 2 O, CO 2 , and microbial biomass [8,9]. Among various microorganisms, bacteria are the most active and the primary hydrocarbon degraders [10].…”

The discharge of hydrocarbons and their derivatives to environments due to human and/or natural activities cause environmental pollution (soil, water, and air) and affect the natural functioning of an ecosystem. To minimize or eradicate environmental pollution by hydrocarbon contaminants, studies showed strategies including physical, chemical, and biological approaches. Among those strategies, the use of biological techniques (especially bacterial biodegradation) is critically important to remove hydrocarbon contaminants. The current review discusses the insights of major factors that enhance or hinder the bacterial bioremediation of hydrocarbon contaminants (aliphatic, aromatic, and polyaromatic hydrocarbons) in the soil. The key factors limiting the overall hydrocarbon biodegradation are generally categorized as biotic factors and abiotic factors. Among various environmental factors, temperature range from 30 to 40°C, pH range from 5 to 8, moisture availability range from 30 to 90%, carbon/nitrogen/phosphorous (C/N/P; 100:20:1) ratio, and 10–40% of oxygen for aerobic degradation are the key factors that show positive correlation for greatest hydrocarbon biodegradation rate by altering the activities of the microbial and degradative enzymes in soil. In addition, the formation of biofilm and production of biosurfactants in hydrocarbon-polluted soil environments increase microbial adaptation to low bioavailability of hydrophobic compounds, and genes that encode for hydrocarbon degradative enzymes are critical for the potential of microbes to bioremediate soils contaminated with hydrocarbon pollutants. Therefore, this review works on the identification of factors for effective hydrocarbon biodegradation, understanding, and optimization of those factors that are essential and critical.

The global use of crude oil for energy applications has increased during the last decades, leading to an extensive release of oil into the environment as well. Thus, contamination deriving from oil spills and industrial wastewater has been recognized as one of the major environmental issues, imposing a serious threat to both human and marine ecosystem health. Treatment of contamination and pollution caused by crude oil constitutes a quite challenging and elaborate process. Among the conventional technologies applied for oil-water separation, oil absorption process has been widely examined in recent years. Commercial sponges, such as melamine and polyurethane sponges, have attracted great attention in the field of crude oil removal both from seawater and industrial wastewater, due to their low cost, high porous three-dimensional (3D) structure, low density, excellent mechanical properties and remarkable reusability. However, the amphipathic nature of commercial sponges limits their application for oil absorption treatment processes. In order to improve their oil absorption performance, several modification methods have been utilized. In the current manuscript, an overview of various methods used for the superhydrophobic/Superoleophilicity modification of commercially available sponges for oil-water separation, is provided, in order to highlight the potential use of these sponges as a novel, highly efficient, low-cost, recyclable and environmental friendly absorbent for the recovery of spilled crude oil both from seawater and industrial wastewater.
