We used microsensors to study the regulation of anoxygenic and oxygenic photosynthesis
(AP and OP, respectively) by light and sulfide in a cyanobacterium dominating microbial …

Before the Earth's complete oxygenation (0.58 to 0.55 billion years [Ga] ago), the photic
zone of the Proterozoic oceans was probably redox stratified, with a slightly aerobic, nutrient …

We used microsensors to investigate the combinatory effect of hydrogen sulfide (H 2 S) and
light on oxygenic photosynthesis in biofilms formed by a cyanobacterium from sulfidic …

Sulfide inhibits oxygenic photosynthesis by blocking electron transfer between H2O and the
oxygen-evolving complex in the D1 protein of Photosystem II. The ability of cyanobacteria to …

Cyanobacterial mats were hotspots of biogeochemical cycling during the Precambrian.
However, mechanisms that controlled O2 release by these ecosystems are poorly …

The diel pattern of vertical migratory movements and photosynthetic activity of Oscillatoria cf.
boryana was monitored periodically in microbial mats of a shallow tepid pond fed by …

We studied the interaction between phototrophic and chemolithoautotrophic sulphide-
oxidizing microorganisms in natural microbial mats forming in sulphidic streams. The …

Seasonal changes in light and physicochemical conditions have strong impacts on
cyanobacteria, but how they affect community structure, metabolism, and biogeochemistry of …

We report the isolation of a pinnacle-forming cyanobacterium isolated from a microbial mat
covering the sediment surface at Little Salt Spring—a flooded sinkhole in Florida with a …

We used a novel amperometric microsensor for measuring hydrogen gas production and
consumption at high spatio-temporal resolution in cyanobacterial biofilms and mats …
