Abstract EN
Pesticides are normally used to control specific pests and to increase the productivity in crops; as a result, soils are contaminated with mixtures of pesticides.
In this work, the ability of Streptomyces strains (either as pure or mixed cultures) to remove pentachlorophenol and chlorpyrifos was studied.
The antagonism among the strains and their tolerance to the toxic mixture was evaluated.
Results revealed that the strains did not have any antagonistic effects and showed tolerance against the pesticides mixture.
In fact, the growth of mixed cultures was significantly higher than in pure cultures.
Moreover, a pure culture (Streptomyces sp.
A5) and a quadruple culture had the highest pentachlorophenol removal percentages (10.6% and 10.1%, resp.), while Streptomyces sp.
M7 presented the best chlorpyrifos removal (99.2%).
Mixed culture of all Streptomyces spp.
when assayed either as free or immobilized cells showed chlorpyrifos removal percentages of 40.17% and 71.05%, respectively, and for pentachlorophenol 5.24% and 14.72%, respectively, suggesting better removal of both pesticides by using immobilized cells.
These results reveal that environments contaminated with mixtures of xenobiotics could be successfully cleaned up by using either free or immobilized cultures of Streptomyces, through in situ or ex situ remediation techniques.
