Reactive oxygen species (ROS) are byproducts of aerobic metabolism and potent agents
that cause oxidative damage. In oxygenic photosynthetic organisms such as cyanobacteria …

Oxidative stress is common consequence of abiotic stress in plants as well as cyanobacteria
caused by generation of reactive oxygen species (ROS), an inevitable product of respiration …

Lignin-derived (eg phenolic) compounds can compromise the bioconversion of
lignocellulosic biomass to fuels and chemicals due to their toxicity and recalcitrance. The …

Approximately 40% of global photosynthesis is conducted by phytoplankton in aquatic
environments. Cyanobacteria, Gram-negative photoautotrophic prokaryotes, contribute …

Tetrapyrroles are involved in light harvesting and light perception, electron-transfer
reactions, and as co-factors for key enzymes and sensory proteins. Under conditions in …

Cyanobacteria are photoautotrophic microorganisms present in almost all ecologically
niches on Earth. They exist as single-cell or filamentous forms and the latter often contain …

Bacteria depend upon iron as a vital cofactor that enables a wide range of key metabolic
activities. Bacteria must therefore ensure a balanced supply of this essential metal. To do so …

Reactive oxygen species (ROS) are inevitably generated as by-products of respiratory/
photosynthetic electron transport in oxygenic photoautotrophs. Unless effectively …

Iron is an essential nutrient for most living organisms. Due to the low solubility of ferric iron at
physiological pH, the transition from an anaerobic atmosphere to the actual oxidant …

The aim of this study was to investigate how acclimation to medium-level, long-term, non-
lethal iron limitation changes the electron flux around the Photosystem II of the oceanic …
