Fungi of traditionally processed Nile fish in Sudan

Abstract

Yeast extract agar media, Potato dextrose agar media, Plate count agar, Plate count agar+, Mannitol salt agar and Eosin Methylene Blue agar were prepared, cultured, incubated and stored following standard methods. The fungal inoculations included 4 replicates, 19 samples, 46 agar media and 7 dilutions form. Aspergillus niger, Aspergillus flavus, Rhizopus stonloifara, Alternaria sp. and Pencillim sp. were detected. The highest fungal count was in wet salted Hydrocynus spp. with 49% moisture and 27% organic content, followed by Alestes spp. with 48% moisture and 32 % organic content. The least fungal count was in dry salted Oreochromis niloticus with 44% moisture and 30 % organic content. No consistent correlates were observed between moisture and organic content, and the fungal isolates or species or the processed fish species.
