“…1) with strain ZF31, constructed based on partial 16S rRNA sequences, showed that the strains were most similar to Pseudomonas sp. previously identified as aerobic denitrifiers able to degrade nitrate (Zhu et al, 2012;Guo et al, 2013). Strain ZF31 showed a high similarity (99.0%) to P. stutzeri, and therefore it was identified as P. stutzeri strain ZF31.…”

“…Traditional wastewater treatments are based on two essential procedures for nitrogen removal: firstly, autotrophic nitrification (oxidation of ammonium to nitrate by nitrifying bacteria under aerobic conditions); secondly, anoxic denitrification (which converts nitrate and nitrite to N 2 gas by denitrifying bacteria under anaerobic conditions) (Zhu et al, 2012).…”

A number of species of Haloferax genus (halophilic Archaea) are able to grow micro aerobically or even anaerobically using different alternative electron acceptors such as fumarate, nitrate, chlorate, dimethyl sulphoxide, sulphide and/or trimethylamine. This metabolic capability is also shown by other species of the Halobacteriaceae and Haloferacaceae families (Archaea domain) and it has been mainly tested by physiological studies where cells growth is observed under anaerobic conditions in the presence of the mentioned compounds. This work summarises the main reported features on anaerobic metabolism in the Haloferax, one of the better described haloarchaeal genus with significant potential uses in Biotechnology and Bioremediation. Special attention has been paid to denitrification, also called nitrate respiration. This pathway has been studied so far from KEY WORDSHaloarchaea, denitrification, anaerobic metabolism, Nox emissions, bioremediation.

“…Isolation technologies are generally designed to prevent off-site movement of heavy metal(loid)s and other contaminants by restricting them within a specified area (Zhu et al, 2012). Soil isolation technology is used to avoid further contamination of groundwater by heavy metal(-loid)s when other remediation methods are not economically or physically feasible.…”

, et al.. A comparison of technologies for remediation of heavy metal contaminated soils. Journal of Geochemical Exploration, Elsevier, 2016Elsevier, , 182, pp.247 -268. 10.1016Elsevier, /j.gexplo.2016 Any correspondence concerning this service should be sent to the repository administrator: staff-oatao@listes-diff.inp-toulouse.fr a b s t r a c tSoil contamination with persistent and potentially (eco)toxic heavy metal(loid)s is ubiquitous around the globe. Concentration of these heavy metal(loid)s in soil has increased drastically over the last three decades, thus posing risk to the environment and human health. Some technologies have long been in use to remediate the hazardous heavy metal(loid)s. Conventional remediation methods for heavy metal(loid)s are generally based on physical, chemical and biological approaches, which may be used in combination with one another to clean-up heavy metal(loid) contaminated soils to an acceptable and safe level. This review summarizes the soil contamination by heavy metal(loid)s at a global scale, accumulation of heavy metal(loid)s in vegetables to toxic levels and their regulatory guidelines in soil. In this review, we also elucidate and compare the pool of available technologies that are currently being applied for remediation of heavy metal(loid) contaminated soils, as well as the economic aspect of soil remediation for different techniques. This review article includes an assessment of the contemporary status of technology deployment and recommendations for future remediation research. Finally, the molecular and genetic basis of heavy metal(loid) (hyper)accumulation and tolerance in microbes and plants is also discussed. It is proposed that for effective and economic remediation of soil, a better understanding of remediation procedures and the various options available at the different stages of remediation is highly necessary.
