Abstract
The influence of six fungicides (benalaxyl, carbendazim, dichlofluanid, folpet, triadimefon and vinclozolin) on the fermentative activity of two lactic bacteria (Lactobacillus plantarum and Leuconostoc oenos) was studied. The possibility of their degradation by these bacteria was also investigated. Benalaxyl, carbendazim, triadimefon and vinclozolin did not show any interaction with the bacteria studied. Dichlofluanid reduced the fermentatwe activity of L. oenos, in proportion to its concentration, while it showed no influence on the fermentative activity of L. plantarum. Dichlofluanid was rapidly degraded by L. plantarum, while its degradation by L. oenos was lower.
