Abstract

Researchers have studied the possible microbes that could be associated with potato tubers. Most researchers reported microbes associated with decayed potato in storage but limited information exist on fungal species associated with non-deteriorated potato and on biochemical composition of specific varieties of potato grown and consumed in Jos, Nigeria. This study seeks to enquire if same or more microbial communities already established in previous studies will be found on identified non-deteriorating potato varieties and their biochemical composition. Identified varieties of Marabel, Caruso, Diamant and Nicola potato were obtained from Root Crop Research Institute, Vom, Plateau State. Fungal species were isolated at 25^oC, 37^oC and 45^oC on Czapek Dox and Potato Dextrose Agar using soil plate method. Biochemical composition was determined by standard protocol. The genera Aspergillus, Mucor, Penicillium, Rhizopus and Fusarium were dominant at 25°C and 37°C while A. Fumigatus grew at 45°C. Of all the fungal species, Aspergillus flavus was dominant while the least was Fusarium oxysporum. The biochemical composition showed that moisture ranged from 71.67 ± 0.15^d to 81.07 ± 0.11^a,Protein ranged from 2.65 ± 0.03^b to 4.13 ± 0.02^a, crude fiber ranged from 3.20 ± 0.10^d to 3.70 ± 0.20^a, lipid ranged from 0.13 ± 0.03^a to 0.33 ± 0.02^a, Ash ranged from of 0.77 ± 0.06^b to 1.16 ± 0.03^a, carbohydrate ranged from 10.48 ± 0.02^d to 19.64 ± 0.02^a, calcium ranged from 0.13 ± 0.01^a to 0.17 ± 0.01^a, phosphorus ranged from 0.03 ± 0.00^b to 0.28 ± 0.20^a and dry matter ranged from 18.67 ± 0.58^d to 28.30 ± 0.20^a across the varieties. Isolated fungi could be attributed to Poor handling of potato and storage conditions while the proximate composition may be based on result of varietal difference.
