Carotenoids from tropical microalgae, Dunaliella sp. : determination of the effects of carotenoids on known pathogens

Abstract

The microalgae of interest on this project are Dunaliella sp. and the pigment of interest to be study on is the carotenoid pigments which happen to be present in this microalgae and other plant. The microalgae is a marine organisms which inhibiting the open ocean, so it is a big interest to study the possibility of the compound called carotenoid in this species either it have the suitable properties to use for human benefit. This compound is only one of three type of pigment that exists in plant. But instead of just a mere pigment it plays a big role to prevent the cell from damage due to stress, the present of this compound help in capturing light of lower wavelength for production of food for the need of the cell. The carotenoid is extracted from a volume of microalgae which is introduce to stress in order to check weather or not a stress can make an algae produces a lot more carotenoid. The extracted carotenoid will then be tested of a volume that is able give LC50 on cancer cell. This is important so that one will know the suitable amount of crude that should be used. The crude will then be tested its microbial activity against certain disease that been cause by Echerichia coli, Bacillus cereus, Pseudomonas aeruginosa, Salmonella, Klebsiella. By this study ones will know the propotion of extract that can be used to produce medicine and the microbial properties that it holds.
