Molybdenum disulfide nanoparticles concurrently stimulated biomass and β-carotene accumulation in Dunaliella salina.

Molybdenum disulfide nanoparticles (MoS NPs) hold tremendous properties in wide domain of applications. In this study, the impact of MoS NPs was investigated on algal physiological and metabolic properties and a two-stage strategy was acquired to enhance the commercial potential of Dunaliella salina. With 50 µg/L of MoS NPs exposure, cellular growth and biomass production were promoted by 1.

Physiological and molecular responses in halotolerant Dunaliella salina exposed to molybdenum disulfide nanoparticles.

Molybdenum disulfide nanoparticles (MoS NPs) has emerged as the promising nanomaterial with a wide array of applications in the biomedical, industrial and environmental field. However, the potential effect of MoS NPs on marine organisms has yet to be reported. In this study, the effect of MoS NPs on the physiological index, subcellular morphology, transcriptomic profiles of the marine microalgae Dunaliella salina was investigated for the first time.

Ethanol induced jasmonate pathway promotes astaxanthin hyperaccumulation in Haematococcus pluvialis.

Haematococcus pluvialis is a main biological resource for the antioxidant astaxanthin production, however, potential modulators and molecular mechanisms underpinning astaxanthin accumulation remain largely obscured. We discovered that provision of ethanol (0.4%) significantly triggered the cellular astaxanthin content up to 3.

Adaptive evolution of microalgal strains empowered by fulvic acid for enhanced polyunsaturated fatty acid production.

Microalgae have emerged as the potential source for value-added products such as polyunsaturated fatty acids (PUFAs). Metabolic engineering of multiple metabolic pathways has promoted eicosapentaenoic acid (EPA) production in microalgae, however, further improvement is warranted owing to the burgeoning demand. Here we improved the microalgal strains by adaptive evolution under hyposalinity treatment, which showed that 70% salinity potentiated the algae to enhance PUFAs.
