Description :
Chromobacterium have been recognize as an important and untapped resourece for novel bioactive compounds. The present research work deals with the in-vitro study of antagonistic activity of Chromobacteria against human pathogenic bacteria. Six chromobacterial strains showed the a very broad range of antagonistic activity against many human pathogeniv bacteria. The Chromobacterial strain were isolated from various sources of Akola district. A total different 60 bacterial culture were isolated from 98 representative samples collected from Akola District. Out of which 76 samples were positive for Chromobacteria and identified as Isolate 1 Pseudomonas aeruginosa, Isolate 2 Acinetobacter indicus, Isolate 3 Serratia marcescens, Isolate 4 Kocuria turfensis, Isolate 5 Kocuria rosea and Isolate 6 Chromobacterium violaceinum. These six species were examined for their ability to antagonize against Staphylococcus aureus, Salmonella typhi, Proteus vulgaris, Klebsiela pnemonae,Pseudomonas aeruginosa and Esherchia coli. The antagonistic activity was interpreted by restricted growth zone of the bacterial pathogen. The diameter of the zone of inhibition respectively. Thisstudy suggest that isolates might be used as potential biological control against human pathogenic bacteria.
