PROCESS FOR OBTAINING COPPER NANOPARTICLES FROM A FUNGUS SELECTED BETWEEN HYPOCREA LIXII AND TRICHODERMA KONINGIOPSIS AND USE OF FUNGI SELECTED BETWEEN HYPOCREA LIXII AND TRICHODERMA KONINGIOPSIS IN BIOREMEDIATION OF WASTEWATER AND PRODUCTION OF COPPER NANOPARTICLES |
摘要 |
The present invention refers to a process for obtaining copper nanoparticles from a fungus selected between Hypocrea lixii and Trichoderma koningiopsis.;The present invention refers to the use of dead biomass of Hypocrea lixii or Trichoderma koningiopsis 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 fungus Hypocrea lixii or Trichoderma koningiopsis. |

1. PROCESS FOR OBTAINING COPPER NANOPARTICLES, from a fungus selected between Hypocrea lixii and Trichoderma koningiopsis comprising the following steps:
a. Isolation of a fungus selected from Hypocrea lixii and Trichoderma koningiopsis; 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 Sabouraud broth resulting in a live biomass; e. Subjecting the live biomass to autoclave resulting in a dead biomass; f. Drying live biomass resulting in a dried biomass; and g. Determination of copper nanoparticles retention in the live, dried and dead biomass. |
