Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Extreme environments as potential drivers of convergent evolution by exaptation: the Atacama Desert Coastal Range case.

Frontiers in Microbiology, 2012
We have recently discovered a variety of unrelated phototrophic microorganisms (two microalgae and one cyanobacteria) in specialized terrestrial habitats at The Coastal Range of the Atacama Desert.

Fog, Symbiosis, and Survival: The Ecological Architecture of the Grit Crust From the Atacama Desert Represents a Lichen Holobiome Rather Than a Soil Microbiome. [PDF]

Environ Microbiol
Multi‐marker metabarcoding (16S rRNA, 18S rRNA, ITS2) of the fog‐dependent grit crust in the Atacama Desert reveals a community structured by lichen symbioses rather than typical soil‐derived microbial assemblages. The green algal photobiont Trebouxia dominates the eukaryotic community, accompanied by lichenized Caliciales and lichen‐associated ...

The Selectivity of Milking of Dunaliella salina [PDF]

Marine Biotechnology, 2009
The process of the simultaneous production and extraction of carotenoids, milking, of Dunaliella salina was studied. We would like to know the selectivity of this process. Could all the carotenoids produced be extracted? And would it be possible to vary the profile of the produced carotenoids and, consequently, influence the type of carotenoids ...

Carotenoid fluorescence in Dunaliella salina [PDF]

Journal of Applied Phycology, 2010
Dunaliella salina is a halotolerant green alga that is well known for its carotenoid producing capacity. The produced carotenoids are mainly stored in lipid globules. For various research purposes, such as production and extraction kinetics, we would like to determine and/or localise the carotenoid globules in vivo.

Effect of Different LED Light Sources on Growth and Pigment Composition of Dunaliella salina Teodoresco (Chlorophyceae)

Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries, 2022
In this study, the effects of red, blue, and yellow LED lights on cell number, growth rate, pigment, and crude oil contents of the green algae, Dunaliella salina Teodoresco, isolated from Ayvalık (Balıkesir) saltworks, were investigated. The highest cell
