Functional kleptoplasts intermediate incorporation of carbon and nitrogen in cells of the Sacoglossa sea slug Elysia viridis

Anders Meibom, Stéphane Laurent Escrig, Charlotte Madeleine Nicole Lekieffre, Michael Kühl

Some sacoglossan sea slugs incorporate intracellular functional algal chloroplasts, a process termed kleptoplasty. "Stolen" chloroplasts (kleptoplasts) can remain photosynthetically active up to several months, contributing to animal nutrition. Whether thi ...

Standardized short‐term acute heat stress assays resolve historical differences in coral thermotolerance across microhabitat reef sites

Nils Rädecker, Gabriela Hannah Holligan Perna

coral thermotolerance differences reflective of in situ reef temperature thresholds. Using a suite of physiological parameters (photosynthetic efficiency, coral whitening, chlorophyll a , host protein, algal symbiont counts, and algal type association), we ...

Bio-optical properties and radiative energy budgets in fed and unfed scleractinian corals (Pocillopora sp.) during thermal bleaching

Niclas Heidelberg Lyndby, Michael Kühl

Corals live in symbiosis with algal dinoflagellates, which can achieve outstanding photosynthetic energy efficiencies in hospite approaching theoretical limits. However, how such photosynthetic efficiency varies with environmental stress remains poorly kno ...

Spatial and temporal changes of primary production in a deep peri-alpine lake

Alfred Johny Wüest, Damien Bouffard, Tiit Kutser

Lake productivity is fundamental to biogeochemical budgets as well as estimating ecological state and predicting future development. Combining modelling with Earth Observation data facilitates a new perspective for studying lake primary production. In this ...

Structure of a PSI-LHCI-cyt b(6)f supercomplex in Chlamydomonas reinhardtii promoting cyclic electron flow under anaerobic conditions

Henning Paul-Julius Stahlberg

Photosynthetic linear electron flow (LEF) produces ATP and NADPH, while cyclic electron flow (CEF) exclusively drives photophosphorylation to supply extra ATP. The fine-tuning of linear and cyclic electron transport levels allows photosynthetic organisms t ...

Cellular pathways of carbon and nitrogen assimilation in kleptoplastic foraminiferal species

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Kleptoplasty is the process by which an organism sequesters algal chloroplasts while discarding or digesting other algal components. This ability is encountered in different organisms, including benthic foraminifera. Among kleptoplastic foraminiferal speci ...

Equilibrium concentration of singlet oxygen in photoreaction of reaction center/carbon nanotube bionanocomposites

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

The reaction center protein is the unit in the photosynthetic organisms in which the primary events of the photoelectric energy conversion take place during photosynthesis. When the photochemistry following the excitation of the reaction center by light is ...

Applications of Nanoparticles for Reactive Oxygen Species (ROS) Scavenging in Photosynthetic Systems

Ardemis Anoush Boghossian

Under aerobic conditions, excessive illumination results in the photogeneration of reactive oxygen species (ROS) responsible for protein damage and photo-inhibition during photosynthesis. We explore the effects of nanoceria (NC), a regenerative ROS scaveng ...

Multi-objective optimization of SNG production from microalgae through hydrothermal gasification

François Maréchal, Adriano Viana Ensinas, Alberto Mian

The conversion of microalgae biomass into biofuels is a quite well explored field of research. Due to high photosynthetic efficiency, microalgae are considered as a potential feedstock for next-generations biofuel conversion processes. This paper addresses ...
