Engineered algae spreads the
modify green algae to reduce the amount of sunlight each cell absorbs
and, counterintuitively, you can increase the amount of sunlight a
mass of algae absorbs. The method promises to boost biofuels production.
The algae cells were modified to have shorter chlorophyll
antenna molecules, which reduces the amount of sunlight a cell absorbs.
This lets sunlight reach more algae cells in a mass of algae, which
boosts the overall productivity of the algae mass.
The mutant algae produced 44 milliliters of oxygen per hour
compared to 23 milliliters for wild algae.
The technique could be applied to algae that produce biofuels
to increase their yields.
