摘要

All strains tested are characterized by proteolytic (caseinolytic) activity, while elastase one was revealed only in two Gracilibacillus strains 6T2 and 7Tl. The activity was high enough (23.1 and 34.7 E/Ml, respectively). These values are at the level of bacterial producers which are described in literature: Bacillus mesentericus 316 M (6 E/Ml), Bacillus thuringiensis IMB B-7324 (50-55 E/Ml). The ability of two strains tested to synthesize enzyme, active against elastine, is important, so far as microbial enzyme may be perspective for using in medicine: elastases are able to dissociation of elastin fibres of connective tissues. These two strains display also fibrinolytic activity, however it was insignificant. Six of eight strains studied manifested alpha-amylase activity (0.01 - 1.173 E/Ml). It was shown that no strains, isolated from the Dead Sea costal ecosystems are able to manifest alpha-L-rhamnosidase activity.
