Abstract EN
Black tea is consumed worldwide and is believed to play a role in cancer prevention.
Xerophilic aflatoxigenic fungi are highly hazardous contaminants of tea since they are associated with tea quality impairment and human health risk.
The present study reports isolation of such xerophilic and aflatoxigenic fungi associated with marketed tea.
Twenty different tea samples collected from the local markets of Tamilnadu, India were investigated for fungal contamination.
The results indicated contamination by 0.38 % Aspergillus flavus.
Other common contaminant fungi including Penicillium spp.
(0.30 %), Pacelomyces spp.
(0.14 %), and Mucor spp.
(0.19 %) were also isolated.
Amongst the fungi isolated Aspergillus niger ML01 and A.
flavus ML02 were found to be xerophilic aflatoxigenic mycoflora.
Phylogenetic analysis based on 28S rRNA revealed their close ancestry.
The chloroform and acetone extracts of spices Elettaria cardamomum and Syzygium aromaticum exhibited antifungal inhibitory activity on growth and toxin elaboration of both these xerophilic tea contaminants A.
niger ML01 and A.
flavus ML02.
The results advocate the use of these spices plant or their extracts as novel antimicrobials which may add preservation and flavour in marketed tea.
