Safety evaluation of blue galdieria extract as a food additive
EFSA Journal, Volume 24, Issue 3, March 2026.Abstract The EFSA Panel on Food Additive and Flavourings (FAF Panel) provides a scientific opinion on the safety of blue galdieria extract as a food additive. Blue galdieria extract is an enzymatically treated C‐phycocyanin extract derived from the lysed biomass of the microalgae Galdieria sulphuraria.

Diversity of microcystin-producing genotypes in Brazilian strains of Microcystis (Cyanobacteria)
Brazilian Journal of BiologyMicrocystis Kützing ex Lemmermann is among the genera of cyanobacteria often associated to toxic blooms with the release of microcystins. A gene cluster codes for microcystin synthetases, which are involved in the biosynthesis of this toxin.

Impacts of microcystin, a cyanobacterial toxin, on laboratory rodents in vivo
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008 Cyanobacterial water blooms became a global problem/issue because beside a dramatic deterioration of water quality parameters they also produce cyanobacterial toxins being harmful for animals and humans.

Cellular transport of microcystin-LR in rainbow trout (Oncorhynchus mykiss) across the intestinal wall: possible involvement of multidrug resistance-associated proteins [PDF]
, 2014 We studied Abcc mediated-transport in middle and posterior intestine of the rainbow trout, Oncorhynchus mykiss. Luminal and serosal transport were evaluated in everted and non-everted intestinal sacs, respectively, incubated with 1-chloro-2,4 ...
