Morphological credentials of Afla-toxigenic and non-toxigenic aspergillus using polyphasic taxonomy

The study was performed for development of macro and micro morphological characters of Aspergillus isolated from groundnut seeds, groundnut cake and soil using cultural and microscopoic methods. Fungus colonies was inoculated in different media like Potato Dextrose Agar (PDA) and Yeast Extract Sucrose (YES) Agar and compared with standard cultures. The Aspergillus isolates grown on both medium were identified using macroscopic characteristics such as colony color, colony reverse color, colony edge, mycelia color, conidation, shape of conidia, conidial wall, mycelium growth, mycelium growth rate and microscopic characteristics including vesicle diameter, conidiophore width, length of conidia head and ascospore diameter.
