Abstract
A chemotaxonomic method for classification of asymmetric penicillia by means of cross-partition in

aqueous two-phase systems combined with SIMCA pattern recognition analysis.



Conidia of three strains each of three closely related Penicillium species in the P.

oiridicatum group were subjected to cross-partition in aqueous polymer two-phase

systems. The cross-point values, the percentage of conidia in the upper phases at the

cross-point and at certain pH values, together with growth-rate measurements on

different culture media were determined and statistically treated using a multivariate

classification computer program (SIMCA). The results showed that the... (More)

Conidia of three strains each of three closely related Penicillium species in the P.

oiridicatum group were subjected to cross-partition in aqueous polymer two-phase

systems. The cross-point values, the percentage of conidia in the upper phases at the

cross-point and at certain pH values, together with growth-rate measurements on

different culture media were determined and statistically treated using a multivariate

classification computer program (SIMCA). The results showed that the different

species were well separated, corresponding with the characterization based on

mycotoxin production. Moreover, the various strains grouped well within the

species. The number of culture media, and thereby the number of variables used in

the analysis, could be reduced without changing the separation properties. (Less)
