Sun, water, CO2 and algae: A recipe for biofuel?

Plant-based biofuels were initially hailed as the answer to all problems posed by traditional fossil fuels. Supply is unlimited and they are also neutral to emissions harmful to the environment also. But using plants has ...

Increasing efficiency of hydrogen production from green algae

New research results from Uppsala University, Sweden, instill hope of efficient hydrogen production with green algae being possible in the future, despite the prevailing scepticism based on previous research. The study, which ...

Algae to capture CO2

Global warming's effects can be seen worldwide, and many experts believe it's only going to get worse as CO2 emissions continue to rise. Global warming is caused by the emission of greenhouse gases. 72% of the totally emitted ...

Photobioreactor enables systems biology studies of cyanobacteria

A novel photobioreactor designed and developed at Pacific Northwest National Laboratory for cultivating photosynthetic bacteria and microalgae will be featured in the journal Bioresource Technology. PNNL researchers are using ...

Genome-scale model of cyanobacterium developed

(Phys.org) -- In an important step toward engineering bacteria to produce biofuel, scientists have developed one of the first global models for the nitrogen-fixing photosynthetic cyanobacterium Cyanothece sp. ATCC 51142 (see ...

Genome of marine organism reveals hidden secrets

An international team of researchers led by scientists at Scripps Institution of Oceanography at UC San Diego has deciphered the genome of a tropical marine organism known to produce substances potentially useful against ...

Hydrogen-making algae's 'Achilles' heel' discovered

(PhysOrg.com) -- Scientists have discovered how oxygen stops green algae from producing hydrogen. The findings could help those working towards 'solar H2-farms' in which microorganisms produce hydrogen fuel from sunlight ...
