Abstract
This study was aimed to isolation and characterization of indigenous fungi from paddy soil. Soil is a living habitat for wide arrays of biotic components. It is an excellent culture medium for the growth and development of various microorganisms including fungi. The soil samples were collected from two different locations of Dhubri District. The observed colonies varied in morphological and microscopic characteristics. A total six genera of fungi were characterized and identified. The isolated fungal strains were successfully identified as Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus, Mucor sp, Trichoderma sp, and Penicillium sp. Relative abundance of all isolated genera was estimated and found that Aspergillus niger showed highest relative abundance and Trichoderma sp showed lowest relative abundance. Aspergillus niger was found to be dominant in the selected paddy fields.
