Scientists continue to study photosynthetic organisms such as cyanobacteria for their potential as bioenergy sources.

More dust, less sunlight, colder oceans, but more dust means that more dust falls on the oceans, which means the more iron fertilization of photosynthetic organisms there is, the higher the level of photosynthesis, so the more CO2 is converted into biomass, so more organic carbon falls to the sea bed, so the more atmospheric carbon disappears into the ocean sink, and also the wider the oxic band at the oceans surface and so more methane is oxidized on the way to the surface.

When photosynthetic organisms first began to generate oxygen, it was the start of a transformation of our world.

Reinhard and Planavsky, together with an international team, have proposed that a scavenging of nutrients in an anoxic (nearly O2 - free) world stunted photosynthetic organisms that otherwise had been poised for at least two billion years to make stockpiles of oxygen.

The researchers imagine photosynthetic organisms might anchor themselves to the sides of cracks, to reach sunlight, while jellyfish - like creatures might ride up and down with the current.

The authors infer — from the way modern photosynthetic organisms react to changing marine arsenic concentrations — that this event was due to widespread ocean toxicity resulting from the release of toxic elements into the oceans when the ice melted.

Photosynthetic organisms typically have multiple different types of ferredoxins, although little is known about how their functions differ.

They probably also created them in the first place, helping to make the first soils and assisting photosynthetic organisms in colonising the land.

Although radiation from Jupiter's magnetosphere would be harmful to life on Europa's surface down to a depth of a few centimeters, sunlight could sustain photosynthetic organisms beneath the ice to a depth of several meters.

algae A large group of mostly photosynthetic organisms, meaning they use light and carbon dioxide to make sugar and oxygen.

And this could have converted CO2 to carbon and O2 long before photosynthetic organisms evolved.

Synthetic genomics may yield microorganisms with novel capabilities, photosynthetic organisms able to generate valuable products directly from CO2, biological systems that increase recovery rates of subsurface hydrocarbons, or advanced plant feedstocks.

Used as a fuel source, it's essentially carbon neutral because photosynthetic organisms survive by metabolizing CO2, a greenhouse gas.
