Elevated accumulation of lutein and zeaxanthin in a novel high-biomass yielding strain Dunaliella sp. ZP-1 obtained through EMS mutagenesis.

ABSTRACT:

Background

Dunaliella microalgae, such as Dunaliella salina riching in β-carotene and Dunaliella bardawil rich in lutein and α-carotene, have been used in aquaculture, supplements, cosmetics, and feed industries. The genus Dunaliella is diverse; therefore, characterization of novel strains and isolation of new varieties through mutagenesis technology will promote natural carotenoid bioproduction.

Results

Salt stress test demonstrated that the newly isolated microalgae strain ZP-1 was a halotolerant strain. Morphology observation and molecular phylogeny analysis indicated that the unicellular green microalga ZP-1 was a member of the genus Dunaliella. Biomass of ZP-1 in RAM medium was up to 2.45 g/L, showing the advantage over other common Dunaliella microalgae in terms of yie
