Effects of electron donors on the microbial reductive dechlorination of hexachlorocyclohexane and on the environment

Comparative Metagenomic Analysis of Soil Microbial Communities across Three Hexachlorocyclohexane Contamination Levels

“…While the results presented here can prove to be an invaluable supplement for the on-going efforts in the development of in-situ bioremediation technologies for HCH, this study also suggests good prospects for developing economically viable HCH bioremediation technology. The latter may involve the use of specific tailor- made nutrients(s) and chemicals like taxa specific minimal salt medium [10], and various electron donors [11]. In addition, this study also points out that bioaugmentation by using a consortium (cultivable representatives of the enriched genera) of both HCH degraders and non-degraders could improve the efficiency of remediation efforts that focus on the use of a single taxon.…”

“…Thus natural attenuation, a process in which microbial community contribute to the pollutant degradation is already in operation but needs to be monitored in detail over several other parameters (salinity, organic wastes and time). Second, for rapid degradation of HCH isomers at the dumpsite, the metagenomic data suggests that it may indeed be possible to effectively biostimulate the indigenous bacterial community by application of specific nutrients that would target the productivity of specific taxa [10]–[11] (taxa specific minimal salt medium and electron donors).…”

“…Owing to the global presence of the HCH open sinks, several primal efforts have focused on developing an efficient bioremediation technology [8]–[11]. As a first step the genetics, biochemistry and physiology of microbial degradation of HCH isomers especially of γ-HCH has been studied in detail in Sphingomonads.…”

Rules and benefits of Life Cycle Assessment in green chemical process and synthesis design: a tutorial review

“…The results of an LCA study can be used to highlight the attractiveness of a novel production pathway; they can help make decisions on which chemical compound to use or it can show optimisation potentials within an existing procedure. 41 The most beneficial way of employing LCA is to apply it in the early development of new compounds or procedures. In this stage, relevant weak points can not only be fixed by after care or so-called end-of-pipe solutions, but they can also be identified and avoided in advance.…”
