A soil contaminated by 10,000 ppm of gasoline (GAS), is a concentration higher than the limit 4,400 established Mexican standard NOM-138-SEMARNAT/SSA1-2003. In soil, it inhibits mineralization organic matter causing loss fertility. Therefore, aims this research a) biostimulation impacted GAS, and b) phytoremediation through Zea mays enhanced with Azotobacter vinelandii to decrease GAS value low...

In this study the ability of Acidithiobacillus ferrooxidans, with regard to the biorecovery of heavy metals inshake flask has been investigated. Adaptation experiments with the single metal ions Ni, Co, V, Mo, W anda mixture of the first four metal ions in the medium was developed through serial sub-culturing. Adaptationshowed that A. ferrooxidans could tolerate up to 2.3 g/l ...

Green nanotechnology with the goal of producing sustainable nanomaterials in an eco-friendly approach is becoming an increasing necessity for nanomanufacturing industries. In this regards, biosynthesis is well adopted as a viable method for producing benign nanoparticles for biomedical application. The present study aimed at optimization and study of the effects of external stimuli pH and gold ...
