Cyanobacterial taxonomy is facing a period of rapid changes thanks to the ease of 16S
rRNA gene sequencing and established workflows for description of new taxa. Since the last …

The classification of life forms into a hierarchical system (taxonomy) and the application of
names to this hierarchy (nomenclature) is at a turning point in microbiology. The …

Photosystem II is the water-oxidizing and O2-evolving enzyme of photosynthesis. How and
when this remarkable enzyme arose are fundamental questions in the history of life that …

Microalgae are a source of scientific curiosity and inspiration for their utilization as
'inoculants' in agriculture and the commercial production of high-value products. Their …

Gut microorganisms are comprised of thousands of species and play an important role in the
host's metabolism, overall health status, and risk of disease. Recently, the discovery of non …

Ancient microbes invented biochemical mechanisms and assembled core metabolic
pathways on an anoxic Earth. Molecular oxygen appeared far later, forcing microbes to …

The photorespiratory repair pathway (photorespiration in short) was set up from ancient
metabolic modules about three billion years ago in cyanobacteria, the later ancestors of …

It is generally accepted that photosynthetic marine planktonic bacteria were responsible for
the oxidation of dissolved ferrous iron (Fe (II)) and the subsequent deposition of iron …

Abstract To date (1 November 2023), the online database AlgaeBase has documented
50,589 species of living algae and 10,556 fossil species here referred to four kingdoms …

Cyanobacteria have played pivotal roles in Earth's geological history, especially during the
rise of atmospheric oxygen. However, our ability to infer the early transitions in …
