Zymographic analysis showed that all subcellular fractions of the serogroups possessed different degree of lipolytical activity. Maximal hydrolysis in the radial enzyme-diffusion reaction in agarose gel was observed in Tween-20, Tween-80, Triton �-305 and Triton �- 405. Total hydrolase activity of urea extracts in Tween-20, Tween-80, Triton �- 405, Span-85 excelled those in the preparations of outer membranes. Maximal lipolytical activity in regard to the Tweens was shown by the preparations of urea extracts prepared from the nontoxigenic strains of O1 serogroups, while in relation to the Tritons � preparations of urea extracts from the toxigenic strains (p < 0,05).
