Battery-Like Bacterial Enzyme Stores Energy Biologically

Posted by Boniface Ndirangu in Energy Storage on April 19, 2012

Clean energy is now an almost achieved dream, especially with the newly reported Concordia University (Canada) physicists’ research findings. The researchers led by Associate Professor László Kálmán have been able to modify a battery-like enzyme so as to yield carbon-neutral energy. The study showed that there is possibility of extending the length of time the bacterial enzyme can store [...]

Mathematical Model Proves Anti-Fungal Paints Negatively Affect Ecosystem, Food Chain

Posted by Ovidiu Sandru in Pollution on December 11, 2011

At least once in your lifetime you’ve heard about anti-fungal painting, or even used it on your own home. Did you know that the same anti-fungal and anti-bacterial properties of such a paint are unbalancing the ecosystem? A scientific study performed in Lausanne, Switzerland, says so. Sylvain Coutu, from École Polytechnique Fédérale de Lausanne (EPFL), [...]

Wood-Breaking Enzyme Discovered in Rhodococcus Jostii, A Soil-Living Bacterium

Posted by Ovidiu Sandru in Biodiesel on June 17, 2011

A team of researchers from the Universities of Warwick and British Columbia have discovered an enzyme in a soil-living bacterium called Rhodococcus jostii which can break down lignin, a component of the woody parts of plants. Their aim is to develop methods to process biomass that doesn’t compete with food crops and that also offer cheap biofuels.

Researcher Finds Method Of Producing Bioplastics From Waste By Training Special Bacteria

Posted by Ovidiu Sandru in Green News on November 22, 2010

A doctoral thesis on the topic of converting agricultural wastes into high-quality bioplastics could reach the first page of newspapers these days. Jean-Paul Meinjen, a researcher at the Technical University of Delft, Netherlands, will be presenting how he actually trained and selected bacteria in an evolutionary process that is not to be neglected by any means.

Cow Rumen Bacteria Provide Groundbreaking Knowledge For Biofuel Industry

Posted by Ovidiu Sandru in Biodiesel on September 8, 2010

They make use of the rumen bacterium as a model, as “it’s one of the most efficient machines to deconstruct plant matter,” said Isaac Cann, associate professor in the U of I Department of Animal Sciences and member of the Energy Biosciences Institute (EBI).

Heavily Modified E.Coli Bacteria to Make Biodiesel for Our Cars – Safe or Not?

Posted by Ovidiu Sandru in Biodiesel on September 7, 2010

E.coli is often associated with food poisoning and sickness. An associate professor of computer science at Rutgers University in Camden, Desmond Lun, is trying to perform a computer simulation of how E.coli could be genetically modified to produce more fatty acids, and hence biodiesel.

Scientists Compartmenting Bacteria to Create Biodiesel and Vaccines

Posted by Ovidiu Sandru in Biodiesel on June 11, 2010

I have always thought that bacteria and genetics are not play with, but it looks like some researchers at the University of Kent and University College Cork have hacked into some simple bacteria’s (like e-coli) inner structure and created compartments where they could synthesize biofuels and vaccines.

Bacteria Colony Reacts with Seawater and Mud to Produce Electricity

Posted by Mihai Sandru in Experiments on February 26, 2010

Until now, scientists haven’t been able to provide the reasons of just how bacteria generate electric networks that serve as long distance communication systems. They have known just that it can produce electric energy when mixed with seawater and mud, leading to the development of microbial fuel cells.

New Discovery: Generating Electricity With Ground Bacteria Shewanella

Posted by Cristi in Energy news, Green News on December 22, 2009

Bio-chemist David Richardson of the University of East Anglia in the United Kingdom said that Shewanella is the ideal candidate for environmental-cleanup tasks as it lives in the underground: “Understanding their biochemistry could help to develop strategies to stimulate their activities [at the cleanup sites].”

Solar-Powered Bacteria Convert Carbon Dioxide Into Biofuel

Posted by Mihai Sandru in Biodiesel, Solar Power on November 16, 2009

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.

BACS: Biodegradable Packaging Fabricated by Bacteria

Posted by Ovidiu Sandru in New Inventions on November 10, 2009

Today’s civilized society sometimes uses weird ways of doing things, like packing software serial numbers in cardboard or a lot of plastic. A project, named Bacs, is using bacteria to make an interesting cellulose material for green packaging.

The Best Way to Generate Electricity from Pig Poop

Posted by Cristi in Energy news, Global Warming on October 26, 2009

Hog farms, where thousands of animals are raised, look really horrible and they pollute rivers, poison groundwater supplies and releaseclouds of methane and carbon dioxide into the atmosphere.

Biodiesel Developed Safely from Rhodococcus Bacteria

Posted by Cristi in Biodiesel on September 29, 2009

Using synthetic biology, researchers from Massachusetts Institute of Technology (MIT) are trying to develop a new bacteria similar to the tuberculosis root to produce biofuel.

Soil-Based Stinky Bacteria To Be Used in Cleaning Radioactive Waste

Posted by Cristi in Nuclear Power on September 16, 2009

A chemistry professor from the University of Missouri may have found a way to clean radioactive metal contamination. The bacteria-based solution is able to work in this challenging business where most of technologies were too expensive or sometimes did not work.

Geobacter Microbe Produces Electricity From Mud and Wastewater

Posted by Ovidiu Sandru in New Inventions on August 12, 2009

Derek Lovley, from the University of Massachusetts Amherst recently experimented with a microbe named “Geobacter”, who loves to live in sediments and mud, and whose hairlike filaments can produce electricity from the muddy environment it loves to live in.
