ABSTRACT

The present study aims at enriching and isolating potential antioxidant producing microorganisms from marine soil obtained from coastline of North-West coastal region of India. A total of 156 bacterial isolates were obtained, which were screened for their potential to produce extracellular antioxidants. Several non-pigmented and pigmented isolates obtained which exhibited good antioxidant producing capabilities. Amongst the seven pigmented organisms exhibiting superior antioxidant activity, two isolates viz. 6-3 and 8-1 demonstrated a varied TLC banding pattern along with a significant DPPH scavenging activity. These isolates were identified morphologically, biochemically and with 16S rRNA identification studies as Janibacter melonis and Pseudomonas stutzeri respectively. The gene sequence of both the organisms was submitted to NCBI and the strains were named Janibacter sp. TKB-1 and Pseudomonas sp. KKB-1 respectively. Key words: Antioxidants, DPPH assay, TLC, Janibacter melonis, Pseudomonas stutzeri
