Abstract

Marine environment is the world of novel precious bio molecules exhibit wide applications mainly clinical significance. Abundant studies carried out to investigate these biologically active molecules from marine organisms bacteria, fungi and actinomycetes. The aim of the study is to isolate and characterize the bioactive pigment from Micrococcus sp from Arabian sea. Marine bacteria were isolated and screened for the biofilm production. The pigment was extracted using acetone and was subjected to antibacterial activity and anti fungal activity tests against some strains using well diffusion method. Pigment extract was characterized with Thin layer chromatography and UV -Vis spectrophotometry. The results found that, the extracted pigment having antibacterial activity and antifungal activity and having the ability to absorb UVA rays within the range of 350-500 nm. The isolated bioactive compound may used against bacterial & fungal infections and can a great future in medicine / cosmetics as a sun protecting agent.
