RESUME
Objectives: The prevalence of mycoflora associated with retail
kolanuts (C. nitida and C. acuminata) obtained randomly across
the North Central States of Nigeria was studied.
Methodology and results: Surface
sterilized tissues of the kolanuts samples were cultured on acidified Potato
Dextrose Agar (PDA) using standard laboratory methods. Twelve fungi isolates,
mostly toxigenic and belonging to nine genera (Aspergillus, Fusarium, Mucor, Lasiodiplodia, Paecilomyces,
Chlamydomyces, Rhizopus, Penicillium and Curvularia) were isolated from the kolanuts tissues. L. theobromae and F. pallidoroseum were the most predominant isolates and the
incidence of L. theobromae on C. nitida was significantly higher (p<0.05)
than other fungi isolates. However, the occurrence of F. pallidoroseum was more frequent than L. theobromae in C. acuminata,
but the difference was not significant.
Conclusion and application of results: Mycoflora
complexes especially of toxigenic potentials were found associated with retail C. nitida and C. acuminata in the north central states of Nigeria, raising
questions on the safe consumption of the crop.
Key words: Mycoflora, retail, C. nitida, C. acuminata, north central, Kolanuts.
