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 …

Eutrophication and deoxygenation possibly occur in coastal waters due to excessive
nutrients from agricultural and aquacultural activities, leading to sulfide accumulation …

The extent of oxygenated environments on the early Earth was much lower than today, and
cyanobacteria were critical players in Earth's shift from widespread anoxia to oxygenated …

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 …

Physiological and molecular phylogenetic approaches were used to investigate variation
among 12 cyanobacterial strains in their tolerance of sulfide, an inhibitor of oxygenic …

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 …

Although the biogeochemistry of the two environmentally hazardous compounds arsenic
and sulfide has been extensively investigated, the biological interference of these two toxic …

Understanding of sulfur metabolism has reached a new dimension with comprehension of
its molecular regulation; however, knowledge underlining the evolutionary perspective and …

Anoxygenic cyanobacteria that use sulfide as the electron donor for photosynthesis are a
potentially influential but poorly constrained force on Earth's biogeochemistry. Their versatile …
