Microfungi Associated with Sun Dried Rastrineobola argentea Sold in Gucha South District in Kenya
Journal Title: Microbiology Research Journal International - Year 2017, Vol 19, Issue 3
Abstract
The mycoflora of sun dried Rastrineobola argentea are associated with deterioration of the fish during sun drying, handling and storage in Gucha South district. A total of six markets were studied from which five wholesalers and thirty retailers were sampled randomly and systematically. A sample of 50 g of Rastrineobola argentea was collected from each participant during the period between September and December 2012. Samples were cultured on dichloran 18% glycerol (DG 18) agar to identify the fungi growing on the dried Rastrineobola argentea. The results obtained showed that thirteen different fungal species were isolated. These were; Absidia spp. (4.05%), Aureobasidium spp. (1.36%), Alternaria spp. (1.36%), Cladosporium spp. (2.70%), Aspergillus niger (17.57%), Aspergillus flavus (9.46%), Aspergillus fumigatus (10.81%), Fusarium spp. (2.70%), Trichoderma spp. (2.70%), Rhizopus spp. (29.73%), Yeasts (5.40%), Penicillium spp. (6.76%) and Mucor spp. (5.40%). The data obtained from the study showed that 83.79% of all the isolates were toxin producing. The presence of mycotoxin producing species in the samples shows that the fish sold in Gucha South district could be a threat to the health of the consumers and therefore measures should be taken to improve their quality.
