Abstract
number of 100 isolates were obtained from rhizospheres of
different crops. Isolates varied greatly in their tolerance to pesticides used depending upon the
applied concentration and tested isolates. Only nine isolates were able to utilize Sencor as a sole
nitrogen source in vitro. Active isolates were completely identified as Streptomyces
rectivioloceus, S. roseolus, S. albosporeus subsp Labilomycaticus, S. herbaricolor and S.
aureomonopodiales.
Results revealed that active Sencor-degrading Streptomyces species varied in the number of
degradation products produced both in vitro and in vivo. Moreover, fast disappearance of Sencor was
reached when soil was inoculated by either of tested species. This diserable effect was more
pronounced when mixture of strains was used. Herbicide-resistant gene (bar) to Basta herbicide was
isolated from some Streptomyces species.
