Biological Activity of Actinomycetes
RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES
................
ABSTRACT:
The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA.
Our project aim is to evaluate some biological activities of Actinomycetes like: • Antimicrobial activity • Oil degradation capability • Enzymatic activity
In the present study, two Actinomycetes strains were isolated from the rhizosphere of Ervatamia divaricata (ornamental plant) and are identified by microscopic characteristics and biochemical tests. With the help of Bergeys manual of determinative bacteriology 7th edition it was established that one isolate belong to Nocardia family and the other one belong to Streptomyces species.
Our isolates not only shown good antimicrobial activity against the test organisms provided (E. coli, S. aureus, P. aerogenosa, B. amyloliquefaciens) but also able to degrade Castrol oil. Out of two isolates one was able to produce Amylase enzyme but lack in producing other enzymes like beta-Glycosidase, Chitinase.
Our work can be taken forward to study many more biological activities. Also each activity we study is a complete project in itself and our results promise for application of our isolates in Amylase production and also possible source of novel antibiotics.
Keywords: Antimicrobial activity, Heavy metal, oil degradation capability and enzymatic activity.
ACTINOMYCETES.
The name`actinomycetes’ was derived from greek `aktis’(a ray) and mykes(fungus) and given to these organisms form initial observation of their morphology.
