Abstract
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.
