Diversity of Penicillium and Aspergillus species isolated from traditional meat products of different Croatian regions
Mycoflora which growth on the surface of traditional meat products (TMP) gives them specific texture, flavour and colour. Composition of mycoflora depends of clime conditions, the most on temperature and humidity. Clime in Croatia is very heterogeneous. Characteristic of Croatian clime is cold and moist winter and hot summer on continental part of Croatia ; moister and mild winter, and very hot and dry summer on the coast. The aim of our study was get an inside of moulds species diversity of mycoflora isolated from 130 samples of TMP from continental (n=68) and coast (n=62) part of Croatia. Isolated mould species were identified using combine classical and molecular methods by beta-tubulin and calmodulin loci sequencing. In the continental region 158 isolates were obtained, thereof 65 % Penicillium species, and 35% Aspergillus species, while in the coastal region where obtained 160 isolates, there of 52% Penicillium and 47% Aspergillus species. In total, 12 different Penicillium and 15 Aspergillus species, mostly teleomorphs, were determined. Among determinate species it has to be emphases that potential mycotoxigenic species, A. flavus (6%) as aflatoxin and cyclopiazonic acid producer, P. commune (47%) as cyclopiazonic acid producer ; P. citrinum (22%) as citrinin producer, and P. nordicum (9%) as ochratoxin producer, were isolated. It could be concluded that Penicillium species, as species which like more continental clime, were isolated more often in continental region then Aspergillus species, which prefer more hot and dry coast clime, and vice versa. Furthermore, isolated micotoxigenic species could represent potential issue for the public health.
