Paper Title
Isolation of Pigment-Producing Bacteria From Surface Water and Study Sun Protection Factor (SPF) of the Purified Pigments
Abstract
During the past two decades research on aquatic bacteria has highlighted because the tremendous potential of
these microorganisms as a source of new bioactive secondary metabolites and it is reported that most of the aquatic bacterial
pigments exhibited biological activity. In the present study, pigmented bacteria were isolated from surface water samples
collected from North West of Iran. The extracted pigments were included: orange pigment (extracted from Exiguobacterium
sp), red pigment (extracted from Serratia marcescens) and pink-red pigment (extracted from Serratia marcescens), SPF value
of the pigments were found to be 1.785,1.629 and 2.72 respectively The results revealed that bacterial pigments have the
ability to absorb UV radiation. Therefore, these agents atoptimum concentrations could produce several beneficial effects to
the skin apart from functioning as an uv filters.
