---|---|---|---|
1. | Aspergillus niger | Growth on PDA is rapid and fast. Powdery black colour almost covering the plates after 72 h | Non-septate conidiophores arising from thick-walled foot cells. Each conidiophores ends in a terminal enlarged spherical swellings. Conidia borne by phialides arising from a terminal swelling on the conidiophores |
2. | Aspergillus oryzae | Growth on PDA is rapid and fast. Powdery brown colour almost covering the plates after 72 h | Non-septate conidiophores arising from thick-walled foot cells. Each conidiophores ends in a terminal enlarged spherical swellings. Conidia borne by phialides arising from a terminal swelling on the conidiophores |
3. | Rhizopus stolonifera | Rapid and fast growth of about 36 mm after 24 h which soon spread and cover the plates. Growth appear as black pin-head, similar to cotton wool (white in colour) | Mycelium of non-septate hyphae of large diameter. The sporangiophore bears a terminal black spherical sporangium. The sporangiophores are erect and may be branched or unbranched each bearing a single globose sporangium |
