Microalgae are proposed to have powerful applications for human health in the pharmaceutical and food industries. Tetraselmis species (sp.), which green microalgae, were identified as a source of broad-spectrum health-promoting biological activities. However, bioactivity these has not been elucidated. We aimed confirm antioxidant, antiviral, anti-inflammatory effects sp. extract (TEE). TEE show...
A remarkable example of biological engineering is the capability of some marine animals to take advantage of photosynthesis by hosting symbiotic algae. This capacity, referred to as photosymbiosis, is based on structural and functional complexes that involve two distantly unrelated organisms. These stable photosymbiotic associations between metazoans and photosynthetic protists play fundamental...
The intracellular localization of calcium during contraction of striated flagellar roots of the green alga Tetraselmis subcordiformis was investigated using calcium pyroantimonate and calcium oxalate cytochemistry and energy-dispersive X-ray microanalysis. Vesicles (0.25 - 0.50 microns diameter) located in the anterior-most region of the cell are calcium-sequestering organelles. These vesicles ...
This study investigated the growth inhibition effects of three phenicol antibiotics on microalgae used in aquaculture. Different dose levels of chloramphenicol (CAP), florfenicol (FF), and thiamphenicol (TAP) were added to cultures of one freshwater green alga, Chlorella pyrenoidosa, and two marine algae, Isochrysis galbana and Tetraselmis chui. For the two marine algae, FF showed higher toxici...
The objective of this research was to establish a chloroplast transformation technique for Platymonas (Tetraselmis) subcordiformis. Employing the gfp gene as a reporter and the bar gene as a selectable marker, transformation vectors of P. subcordiformis chloroplast were constructed with endogenous fragments rrn16S-trnI (left) and trnA-rrn23S (right) as a recombination site of the chloroplast ge...
Green microalgae contain many active pigments such as carotenoids having antioxidant and protective activity on human cells. Here we investigate the biological activity of an ethanol/water extract of the marine green microalga Tetraselmis suecica containing high levels of carotenoids such as the xanthophylls lutein, violaxanthin, neoxanthin, antheraxanthin and loroxanthin esters. This extract h...
