摘　　要：The pigments are vital parts of photosynthetic machinery in algae and exhibit a myriad of applications as nutraceuticals,cosmetics,colorants,which find huge applications in many industires,including the paint industry and paper industry.The antimicrobial,antioxidative,anti-inflammatory,and anti-cancer potential of microalgal pigments contribute towards their varied industrial applications.In this study,pigments(Fucoxanthin,C-phycocyanin,and C-phycoerythrin),extracted from microalgae were investigated to check the antimicrobial efficacy using agar well diffusion and disc diffusion methods against pathogenic bacteria:Staphylococcus aureus and Escherichia coli.The fucoxanthin pigment isolated from diatom Thalassiosira sp.exhibited the highest antibacterial activity against Staphylococcus aureus(17±1.53 mm)and in contrast fucoxanthin pigment isolated from Chaetoceroes sp.exhibited the highest bactericidal activity against Escherichia coli(18±1).The pigment extract of Spirulina plantesis showed the highest antibacterial activity against E.coli(41±0.3)and S.elongatus also exhibited high antibacterial activity against E.coli(32±0.5)while Anabaena variabilis showed the highest antibacterial activity against Staphylococcus aureus(34±0.5).The potential of microalgal pigments is highly valuable and further extensive studies can elaborate the underlying mechanisms.
