Bioaugmentation of anaerobic sludge with long-chain fatty acids (LCFA)-degrading bacteria can be a feasible strategy to enhance methane production from LCFA. This hypothesis was studied in batch assays with Syntrophomonas zehnderi as bioaugmenting strain. This bacterium is able to degrade a wide range of saturated and unsaturated LCFA, and its presence has been reported in several oleate-fed bi...

Worldwide, contamination of soil and ground water is a severe problem. The negative effects of pollutants on the environment and on human health are diverse and depend on the nature of the pollution. The search for alternative methods for excavation and incineration to clean polluted sites resulted in the application of bioremediation techniques. In this review, we describe some generally accep...

Fish are a rich source of proteins beneficial to heart and eyes. Being perishable, they are processed immediately after collection. Water consumption in fish-processing industry is very large and high strength wastewaters rich in salts, ammoniacal nitrogen (NH3-N), organic load are generated which cannot be discharged without any treatment. The present investigation describes development of bio...

Batch nitrification tests were conducted with sludge and wastewater streams obtained from field implementations to evaluate nitrification inhibition and efficiency of a nitrifiers bioaugmentation technology at full-scale municipal wastewater treatment plants (WWTPs). The results showed that the substrate organic carbon and pH of wastewater streams were inhibitory factors to nitrification and th...

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...

Nitrobenzene is highly toxic liquid aromatic compound which is readily absorbed through the skin. Although nitrobenzene is not currently known to be a carcinogen, prolonged exposure may cause serious damage to the central nervous system, impair vision, cause liver or kidney damage, anaemia and lung irritation. Natural attenuation, biostimulation and bioaugmentation of nitrobenzene contaminated ...

Floating treatment wetlands (FTWs) are cost-effective systems for the remediation of polluted water. In FTWs, metabolic activity microorganisms associated with plants is fundamental to efficiency. Bioaugmentation, addition pollutant-degrading capabilities, appears be a promising means enhance efficiency FTWs. Here, we quantified effect bioaugmentation four-membered bacterial consortium on water...

To evaluate atrazine behavior in an agricultural soil (adsorption–desorption, leaching) and the effects of bioaugmentation with Arthrobacter sp. strain AAC22, as a remediating strategy. An history application was used. Equilibrium batch experiments allowed investigation adsorption–desorption at different depths, while leaching potential assessed using disturbed columns. AAC22 selected for bioau...
