摘要：Fucoxanthin is an orange pigment found in brown sea algae,diatoms,and dinoflagellates.Fucoxanthin,known to have anticancer,antihypertensive,antipyretic,high antioxidant activity and antiobesity effects.Considering that brown algae rich in fucoxanthin are of great importance,the search for alternative sources of this carotenoid has been ongoing for a long time.The study was conducted to determine the effect of different salinity concentrations on the biomass productivity and fucoxanthin contents of Phaeodactylum tricornutum,Thalassiosira weiss-flogii and Nitzschia closterium forma minutissima biomass.While the highest biomass amounts of the three diatom species P.tricornutum and N.closterium f.minutissima were determined at 40%o salinity,T.weissflogii was determined at 30%o salinity.In terms of species,the highest amount of biomass was determined in N.closterium f.minutissima with 0.523gL-1.The lowest biomass content was detected in T.weissflogii.The highest fucoxanthin contents were determined in T.weissflogii and N.closterium f.minutissima in 30%o salinity,while the lowest value was determined in P.tricornutum with 30%o salinity.From the perspective of both biomass and fucoxanthin,N.closterium f.minutissima showed the best improvement in 30%o salinity.
