Field scale biodegradation of total petroleum hydrocarbons and soil restoration by Ecopiles: microbiological analysis of the process.

Ecopiling is a method for biodegradation of hydrocarbons in soils. It derives from Biopiles, but phytoremediation is added to biostimulation with nitrogen fertilization and bioaugmentation with local bacteria. We have constructed seven Ecopiles with soil heavily polluted with hydrocarbons in Carlow (Ireland).

[Overview of systematic reviews of Shufeng Jiedu Capsules].

At present, there have been many clinical trials and systematic reviews/Meta-analysis proving the good clinical efficacy of Shufeng Jiedu Capsules in the treatment of respiratory diseases, while comprehensive discussion is still required. This article overviews and analyzes the systematic reviews/Meta-analysis of Shufeng Jiedu Capsules to provide evidence support for clinical practice. The systematic reviews/Meta-analysis of Shufeng Jiedu Capsules were searched from CBM, Wanfang, CNKI, VIP, PubMed, EMbase and Cochrane Library.

Enzyme cocktail containing NADH regeneration system for efficient bioremediation of oil sludge contamination.

Oil sludge is one kind of toxic and persistent contamination to ecology system from petroleum industry. In order to recycle contaminated sands and reduce environmental impacts at a lower operating cost, enzyme cocktail 21/CbFDH including NADH regeneration system for oily sludge bioremediation was constructed for the first time. The intracellular enzymes of oil-degrading strain Acinetobacter calcoaceticus 21 were prepared and the formate dehydrogenase gene Cbfdh from Candida boidinii was cloned and functionally expressed in E.
