A Comparison of β-Carotene, Phytoene and Amino Acids Production in <i>Dunaliella salina</i> DF 15 (CCAP 19/41) and <i>Dunaliella salina</i> CCAP 19/30 Using Different Light Wavelengths

A Comparison of β-Carotene, Phytoene and Amino Acids Production in <i>Dunaliella salina</i> DF 15 (CCAP 19/41) and <i>Dunaliella salina</i> CCAP 19/30 Using Different Light Wavelengths

Strains of <i>Dunaliella salina</i> microalgae are of considerable research and industrial interest because they hyper-accumulate β-carotene as well as produce high-quality protein. To explore the co-production of valuable compounds in <i>D. salina</i>, this study compared th...
