[Comparative estimation of biocides and crown-ethers effect on micromycete-destructors cultures]

Influence of catamine AB, catapine, macrocyclic polyethers (crown-ethers [15]C-5, B[15]C-5, [18]C-6, B[18]C-6, DCH[18]C-6, DA[18]C-6) and mixtures of catapine with crown-ethers on fungal test-cultures of Aspergillus sydowii (Bain. et Sart.) Thom et Church, Cladosporium cladosporioides (Fr.) de Vries and Penicillium tardum Thom. It is shown, that solutions of catamine AB show the inhibiting effect in concentrations which are one level lower than in catapine. Inhibition influence on the growth of fungal test-cultures is found to be higher for crown-ethers B[15]C-5 and B[18]C-6 in contrast to [15]C-5 and [18]C-6 (B[15]C-5 > [15]C-5; B[18]C-6 > [18]C-6). Synergism of inhibition influence of catapine-bactericide and crown-ethers in the mixture on fungal cultures is established in contrast to influence of separate components of the mentioned substances.
