ABSTRACT

Micrococcus is a genus of bacteria in the Micrococcaceae family. Micrococcus roseus widely range of environments including water, dust and soil. Micrococci species are Gram positive cocci and size ranges from about 0.5-3 micrometres in diameter and appear in tetrads. Natural pigments are extracted not only from fruits, vegetables and roots. The synthetic colours are highly toxic and expensive. It is essential to produce Biocolors. Pigments are bio active secondary metabolite in microbes because of Carotenoids effect on UV radiation of sun and reactive oxygen species. Microorganisms are found in paper notes because of the rough surface which allows them to settles for long periods. The level of contamination depends on how long the note should been in circulation with one hand to another, The microorganisms has capacity to absorb moisture and its texture. Microorganisms present for a long time for production of molecules like antibiotics, enzymes, It is more stable and soluble. This study showed that crude acetone pigment extracts exhibited most potent antibacterial activity against Staphylococcus aureus isolate by performing well diffusion using different concentrations of crude pigment extract ranging from 500μl to 62.5 μl exhibiting inhibitory values of 19 mm and 15 mm at 500 μl and 250 μl . The isolate was found to be resistant to pigment extracts at concentration range of 125 μl and 62.5 μl.

Keywords: Muller Hinton agar, Carotenoids Pigment, Spectrophotometer.
