| − | Nowadays, platinum ressources are an issue because they are going to disappear above 2064 and | + | Nowadays, platinum ressources are an issue because they are going to disappear above 2064 and not any alternative has been found so far. Our goal is to find an other source of platinum than mines. Accumulation of the metal on the road side has been frequently shown since the beggining of the 21th. Futhermore, alternatives methods to recycle precious metal are investigated. Here, we use the adsorption potentiel of bacterial natural componant (specifically flagellum and biopeptides) to make a process ables to extract or concentrate the platinum available on different compartiments like soil, plants, sewege sludge... |

Since a law from 1993, platinum is largely used in catalytic converter to avoid toxic gaz release <ref>J. de Aberasturi, et al., Minerals Engineering 24, 505 (2011)</ref>. . During the automobile fonctionnement, the precious metal is rejected and deposed on the road under a ionic form <ref>P.S Hooda & al. 2007, https://www.ncbi.nlm.nih.gov/pubmed/17604084</ref><ref>Liliane Michel Legret & al. http://link.springer.com/article/10.1007/s11368-012-0491-3.</ref> Platinum leaching makes an accumulation of this metal on the road side. By default, it has been prooved that plants are potentiel bioaccumulator of platinum, which is found concentrated on the roots, leaves.. Otherwise, the metal is also carried on the sewage sludge and is actually an issue regarding the recycling potential of these sludge. | Since a law from 1993, platinum is largely used in catalytic converter to avoid toxic gaz release <ref>J. de Aberasturi, et al., Minerals Engineering 24, 505 (2011)</ref>. .
