PROCESS FOR OBTAINING COPPER NANOPARTICLES FROM RHODOTORULA MUCILAGINOSA AND USE OF RHODOTORULA MUCILAGINOSA IN BIOREMEDIATION OF WASTEWATER AND PRODUCTION OF COPPER NANOPARTICLES
The present invention refers to a process for obtaining copper nanoparticles from Rhodotorula mucilaginosa. The present invention refers to the use of dead biomass of Rhodotorula mucilaginosa to perform bioremediation of wastewater and for industrial scale production of copper nanoparticles. In the present invention, it is developed a synthetic strategy for the biosynthesis and removal of copper nanoparticles which is fast, low cost, environment friendly and easily scalable, using as a reduction agent the yeast Rhodotorula mucilaginosa.
1 . PROCESS FOR OBTAINING COPPER NANOPARTICLES from Rhodotorula mucilaginosa comprising the following steps:
a. Isolation of the yeast Rhodotorula mucilaginosa;
b. Determination of copper tolerance of the isolated fungus of step a;
c. Preparation of a copper stock solution;
d. Addition of said isolated fungus in the medium culture YEPD broth resulting in a live biomass;
e. Subjecting the live biomass to autoclave resulting in a dead biomass; and
f. Determination of copper nanoparticles retention in the live and dead biomass.
2 . USE OF A YEAST EXTRACT, selected from Rhodotorula mucilaginosa extract to perform bioremediation of wastewater.
3 . THE USE, according to claim 2 , wherein Rhodotorula mucilaginosa extract is dead mass of Rhodotorula mucilaginosa.
4 . THE USE, according to one of the claims 1 to 3 , wherein it is for the production of copper nanoparticles.
5 . COPPER NANOPARTICLE, produced from a yeast selected Rhodotorula mucilaginosa during a bioremediation of wastewater.
