for the fungistatic effect, we used Penicillium chrysogenum and Aspergillus niger strains, also present in the collections of previously cited laboratory; the tests were conducted in Laboratory of Microbiology from Biological Research Institute, Iasi, by using the method described by SCHADLER et al., 2006, consisting in fungi cultivation on Sabouraud media; the colonies were measured at 5 and 10 days, moment when the colonies of control cultures reached
the edges of the Petri dish; for the oval colonies, more diameters were measured, finally the average value of the measurements being considered; the comparative inhibition of growth was calculated using a specific formula by which the growth inhibition is determined, in % face to control
