This work was aimed at evaluating the relative merits of bioaugmentation, biostimulation and surfactant-enhanced bioavailability of a desert soil contaminated by crude oil through biopile treatment. The results show that the desert soil required bioaugmentation and biostimulation for bioremediation of crude oil. The bioaugmented biopile system led to a total petroleum hydrocarbon (TPH) reductio...
Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of thes...
the aim of this research was to optimize bioremediation of seawater samples spiked with 1000 mg/l crude oil for removal of n-alkanes (c12h26 to c34h70). bioaugmentation experiments were performed at laboratory scale: each bioreactor contained 250 ml dispersed crude-oil-contaminated seawater, indigenous acclimatized microorganism and nitrogen and phosphorus at concentrations based on central com...
nickel (ni) is a heavy metal and soil pollutant but existence of small amount of it as a metallic part of urease enzyme in the plants is necessary. remediation of spots contaminated with heavy metals is particularly challenging. phytoremediation, the use of plants for environmental restoration, is a novel clean up technology. in this study, five levels of nickel [control (ni0), ni125, ni250, ni...
The contribution of emerging amphibian diseases to the sixth mass extinction is driving innovative wildlife management strategies, including the use of probiotics. Bioaugmentation of the skin mucosome, a dynamic environment including host and microbial components, may not provide a generalized solution. Multi-omics technologies and ecological context underlie effective implementation.
Bioaugmentation of bioreactors focuses on the removal of xenobiotics, with little attention typically paid to the recovery of disrupted reactor functions such as ammonium-nitrogen removal. Chloroanilines are widely used in industry as a precursor to a variety of products and are occasionally released into wastewater streams. This work evaluated the effects on activated-sludge reactor functions ...
The objective of this study was to improve the mineralization metronidazole, a recalcitrant antibiotic by development new combined process coupling electro-Fenton and biological process. For biotreatment, various strategies were considered bioaugmentation, bioacclimatation biostimulation alone or combined. So, novelty strategy is combine advanced oxidation with conventional biotreatment activat...
