Comparative analysis of ZISO-mediated carotenoid biosynthesis in Dunaliella salina and Dunaliella bardawil

International Microbiology
Carotenoids are essential natural pigments, and ZISO plays a pivotal role in their biosynthesis. This study compares ZISO enzyme activity in Dunaliella salina and Dunaliella bardawil to evaluate their efficiency in synthesizing 9,9'-di-cis-ζ-carotene. Bacterial strains lacking ZISO (ΔDsZISO, ΔDbZISO) and ZDS (ΔDsZDS, ΔDbZDS) were constructed, and HPLC ...

Lipid composition of halotolerant algae, Dunaliella parva lerche and Dunaliella tertiolecta

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1982
Abstract The lipids of two halotolerant algae, Dunaliella parva Lerche and Dunaliella tertiolecta , contained predominantly the glycolipids monogalactosyldiacylglycerol (21.4 and 22.2 mol% for D. parva and D. tertiolecta , respectively), digalactosyldiacylglycerol (11.4 and 20.5 mol%), sulfoquinovosyldiacylglycerol (6.5 and 9.5 mol%) and two ...

Effects of titanium nanoparticles on the photosynthesis, respiration, and physiological parameters in Dunaliella salina and Dunaliella tertiolecta

Protoplasma, 2019
The development of nanotechnology and the upsurge of interest in titanium dioxide (TiO2) nanoparticles, especially the anatase and rutile crystalline phases, in consumer products such as paint and sunscreen, has polluted the aquatic environment and had adverse effects on living organisms, especially algae.

Localization of glycollate dehydrogenase in Dunaliella salina

Planta, 1987
Glycollate dehydrogenase of the halotolerant green alga Dunaliella salina, isolated from a brine pond, was found associated with the membrane fraction which exhibited complete photosynthetic activity. Highest enzyme activity was found in cells grown in the presence of 5% NaCl.

Comparison of flocculation methods for harvesting Dunaliella

Bioresource Technology, 2015
Low cell concentrations of Dunaliella salina in production scale cultivations require high energy input for biomass harvesting. Flocculation is a potential preconcentration method to lower the dewatering costs for the β-carotene production. In the present study, optimal flocculant dosages were determined for several metal salts, NaOH, Ca(OH)2 and Al ...

Sucrose biosynthesis in Dunaliella

Planta, 1978
The halotolerant phytoplankton alga Dunaliella tertiolecta was found to be able to synthesize considerable amounts of sucrose. Because this is in contradiction to the current literature, the physiologic conditions required for sucrose biosynthesis were investigated.

Investigation of Photomovement in Dunaliella

2010
To study photomovement in Dunaliella, a special experimental videomicrography system was developed. It allows the observation and measurement of the velocity and direction of movement of individual cells as modulated by light stimulus parameters. The system utilizes a microscope connected to a light source, monochromator and videosystem (Fig. 4.1).
