Type of Meat | Morphological Description of Colonies | Microscopic Appearance | Suspected Organism |
Muscles | White cottony at first then grey as it grow older | Sporangiophores arise singly from mycelium at any point. All branches terminate in sporangia | Mucor |
Black dusty and spongy throughout the storage time | Sporangiophores arises from long arching stolons opposite rhizoids | Rhizopus stolonifer | |
Dark-brown to black pigmentation | Numerous mycelia conidiophores are black, spherical to oval, produced in long chain | Aspergillus niger | |
Colony appeared to be circular, white and creamy | Single cells, oval in shape with some cells showing budding | Saccharomycetes | |
Pinkish surface with white underneath | Conidiophores bear branched sterigmata, each with chain of conidiophores | Peniciliumspp | |
Yellow green surface with reddish brown underneath | The apex of the conidiophores is swollen into a vesicle from which arises bottle shaped cells, sterigmata which bear chains of secondary sterigma | Aspergillus flavus | |
Offal | Darkish-brown to black pigmentation | Numerous mycelia conidiophores are black, spherical to oval, produced in long chain | Aspergillus niger |
