The principle aims of this study were to isolate dye degrading actinomycetes
from textile industry effluent, to characterize the obtained isolates and to
screen them for azo dye degradation. Experiments included collection of soil
samples; isolation of actinomycetes by serial dilution and spread plate
technique on ISP2 medium ; characterization for their microscopic,
physiological and biochemical properties; and screening for azo blue and
azo orange dye degradation. Soil samples collected from two locations around
textile dye industry at Palakkad, Kerala were used for isolation. Isolates obtained
were identified as Streptomyces spp. on the basis of their morphological,
physiological and biochemical properties. The two isolated Streptomyces spp.,
being indigenous in nature presented significant ability to degrade azo blue
and azo orange dyes. However precise identification requires further studies
including molecular characterization. Optimization of conditions to yield
better degradation and further studies with these organisms will provide
insights into metabolic pathways, responsible enzymes, and their role in
bioremediation of textile industry effluents.
