Researchers at Virginia Bioinformatics Institute have
assembled the draft genome of a marine algae sequence to aid scientists across
the U. S.
in a project that aims to discover the best algae species for producing
biodiesel fuel. The results have been published in Nature Communications.
The necessity of developing alternative, renewable fuel
sources to prevent a potential energy crisis and alleviate greenhouse gas production
has long been recognized. Various sources have been tried—corn for ethanol and
soybeans for biodiesel, for example. But to truly meet the world’s fuel needs,
researchers must come up with a way to produce as much biofuel as possible in
the smallest amount of space using the least amount of resources.
Enter algae. Unlike other crops like corn or soybeans,
algae can use various water sources ranging from wastewater to brackish water
and be grown in small, intensive plots on denuded land. While algae may still
produce some carbon dioxide when burned, it can sequester carbon during growth
in a way that fossil-fuel based energy sources obviously can’t.
Scientists in VBI’s Data Analysis Core (DAC), Robert
Settlage, PhD, and Hongseok Tae, PhD, assisted in the assembly of the genome of
Nannochloropis gaditana, a
marine algae that may be capable of producing the lipid yields necessary for a
viable fuel source.
“Getting the data is now the easy part. What we’re doing
in the DAC is enabling researchers to move beyond informatics issues of
assembly and analysis to regain their focus on the biological implications of
their research,” said Settlage.
Further analysis revealed that with fairly
straightforward genetic modification, N.
gaditana should be capable of producing biofuel on an industrial
scale, which may be the wave of the future in fuel research and production.
