Coccolitophores, such as Gephyrocapsa huxleyi , can have multiple interesting biotechnological applications thanks to their ability to produce complex structures made of CaCO 3 , called coccolith, and a biomass rich in valuable molecules. Unfortunately, they usually reach low cellular density in standard conditions, hindering actual industrial applications. To enhance growth, CaCO 3 may be used instead of standard CaCl 2 . Her...

Microalgae are versatile microorganisms that produce bioactive compounds with antioxidant, anti-inflammatory, and antimicrobial properties. Neochloris oleoabundans stands out for its adaptability and promising potential in a wide range of biotechnological applications, including the synthesis of high-value metabolites. Among the bioactive molecules of interest, extracellular vesicles (EVs) are gaining increasing attention for...

Main conclusion A structural re-modeling of the thylakoid system, including granum size and regularity, occurs in chlorophyll-deficient wheat mutants affected by photosynthetic membrane over-reduction. Abstract In the chloroplast of land plants, the thylakoid system is defined by appressed grana stacks and unstacked stroma lamellae. This study focuses on the variations of the grana organization occurring in outdoor-grown wheat...

Within the ancient vascular plant lineage known as lycophytes, many Selaginella species contain only one giant chloroplast in the upper epidermal cells of the leaf. In deep-shade species, such as S. martensii , the chloroplast is cup-shaped and the thylakoid system differentiates into an upper lamellar region and a lower granal region (bizonoplast). In this report, we describe the ultrastructural changes occurring in the giant...

Microalgae are studied as innovative sources of a wide range of highly valuable products, including proteins for the food/feed sectors. However, protein content varies depending on algal species, culture conditions and harvesting period. The Phylum Chlorophyta includes most of the described species of green algae. Due to their remarkable peculiarities, four Chlorophyta species belonging to two distinct classes were selected fo...

The biotechnological potential of microalgae has gained considerable importance in many applied fields: biomass production for food and feed, cosmeceutical and pharmaceutical products, energy and phytoremediation. The driving force that inspires the progress in microalgae production is the need for new cultivation systems to obtain simultaneously the maximum yield, reduction of water and nutrients use, and production of econom...
