Algae Producing Fuel Through Photosynthesis With the Help of Engineering

Mila Luleva — Tue, 08 Jan 2013 20:12:44 +0000

New species of blue-green algae was engineered by chemists at University of California, Davis. The aim of the team, led by assistant professor Shota Atsumi, was to find a replacement of petroleum and natural gas to produce chemical feedstock. The findings were published in the latest Proceedings of the Academy of Sciences. The unique study looked […]

Photosynthetic Cyanobacteria Produces Sugar for Biofuel

Mila Luleva — Mon, 17 Dec 2012 18:59:20 +0000

Sugar is one of the key elements involved in the production of ethanol and determining the cost of biofuels. A new initiative called Proterro, intends to produce ultra-cheap sugar by using photosynthetic microorganisms. Proterro raised $3.5 million in a financing round in addition to the previous $5 million. The photosynthetic cyanobacteria has been engineered to […]

Biological Switch Helps Optimize Algae Biofuel Production

Maria Reyes — Mon, 23 Jul 2012 16:02:55 +0000

Researchers have discovered a biological switch in blue-green algae that reacts to light, thereby altering the movement of electrons inside the cell. The new findings could help optimize biofuel production by algae. Algae are prime targets for biofuel production. They are non-feedstock and will not compete with arable land for their growth and production. They […]

Global Warming Prevents Water Turnover in Lake Zurich

Maria Reyes — Tue, 17 Jul 2012 20:44:21 +0000

The University of Zurich reports that there is insufficient water turnover in Lake Zurich because of global warming. This phenomenon favors the growth and proliferation of the harmful Burgundy blood algae in the lake. Water turnover usually occurs during the winter when the entire lake cools down. Intensive winds trigger the turnover or exchange of […]

Health Threats from Exponential Growth of Cyanobacteria Due to Global Warming

Maria Reyes — Wed, 04 Jul 2012 21:42:32 +0000

Cyanobacteria are aquatic microorganisms that thrive best in warm waters. Global warming has been linked to the exponential growth of these microorganisms in natural waters that poses a serious threat to human health. These microorganisms can produce toxins harmful to the cells, nervous system, liver and other organs in the body. Rehab El-Shehawy expressed concerns […]

Solar-Powered Bacteria Convert Carbon Dioxide Into Biofuel

Mike Sandru — Mon, 16 Nov 2009 20:06:25 +0000

A team of U.S. researchers have developed a new way to generate alternative fuel from bacteria. They have genetically modified bacteria to eat CO2 and produce isobutyraldehyde, which can further be used to produce isobutanol.
