Se realizaron pruebas de toxicidad con elutriados sedimentos marinos provenientes las bahías Los Chimus, Tortugas y Casma, en Perú, empleando microalgas marinas Isochrysis galbana Nannochloropsis oceanica. Las muestras sedimento marino se colectaron los meses marzo agosto 2016. Estas siguiendo protocolos estandarizados, mediante estáticas a 96 h exposición. Previamente, determinó la sensibilida...
Background and Aims: This study was aimed to investigate the anti-cancer effect of Isochrysis galbana microalgae extract. Methods: In study, chemical composition extract analyzed, its cytotoxic against K562, HL60, U937, MOLT-4, Raji cancer cells investigated. ECV304 endothelial were used as a healthy cell line for understanding selective cytotoxicity. To determine effects extract, an MTT cytoto...
We have performed life table experiments to investigate the effects of different food types and concentrations on the larval development and survival up to adulthood of Acartia tonsa. The food species offered comprised a wide taxonomic spectrum: the pigmented flagellates Isochrysis galbana, Emiliania huxleyi, Rhodomonas sp., Prorocentrum minimum, the diatom Thalassiosira weissflogii, grown on m...
The understanding of algal phylogeny is being impeded by an unknown number of events of horizontal gene transfer (HGT), and primary and secondary/tertiary endosymbiosis. Through these events, previously heterotrophic eukaryotes developed photosynthesis and acquired new biochemical pathways. Acetyl-CoA carboxylase (ACCase) is a key enzyme in the fatty acid synthesis and elongation pathways in al...
The aim of this study was to assess the effect of dietary eicosapentaenoic acid (20:5n-3) on hemocyte parameters such as hemocyte concentration, phagocytosis, and non-stimulated reactive oxygen species (ROS) production in Pacific oysters Crassostrea gigas, as well on proximate biochemical and fatty acid compositions. One-year-old oysters (C. gigas) were fed T-Isochrysis aff. galbana (T-Iso), wh...
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...
Two Iranian strains of Brachionus rotifers were cultured under different food and salinity regimes. The rotifers were fed with five algal types (freshwater and marine Chlorella vulgaris, Nannochloropsis occulata, Isochrysis galbana and Scenedesmus obliquus) at three different salinities (5, 15 and 25 g/L) and their reproductive and growth parameters were assessed. The maximum number of ovigerou...
