Abstract

An indigenous fungal strain was isolated from Indian Kolar Gold Field mine soil. The isolate was heterothallic, branched septate, deeply floccose, fast-growing, dull green with white background conidial columnar mycelium from Aspergillus section Fumigati. Diverse metabolic patterns of the isolate exhibit high metal, thermal resistance which grews well from 28 ? 1^oCto 37^oC and pH concentration was significant on the growth of isolate. Phylogenetic analysis of 16srRNA β-Tubulin gene sequence established relationship among isolate and other taxa. Molecular identification and morphological features of fungal isolate were consistent with those of Neosartorya udagawae. Heterothallic N.udagawae FJ830683 strain was closely related to homothallic N. aureola EF661890. Fungal isolate extract synthesized narrow sized stable Gold nanoparticles (AuNPs).?
