Bacteria serves tasty solution to global plastic crisis

Scientists have devised a novel way of tackling the mounting issue of plastic pollution -- by using bacteria to transform plastic waste into vanilla flavoring

14-Jun-2021

Researchers have discovered that the common bacteria E. coli can be deployed as a sustainable way to convert post-consumer plastic into vanillin, a new study reveals. Vanillin is the primary component of extracted vanilla beans and is responsible for the characteristic taste and smell of ...

Sustainable use of CO2 using a modified bacterium

13-Mar-2020

A team of scientists from the Max Planck Institute of Molecular Plant Physiology in Potsdam-Golm, led by Dr. Arren Bar-Even, has succeeded in reprogramming the diet of the bacterium E. coli in such a way that it can use formic acid or methanol as its sole source of nutrition. These simple organic ...

Bacteria-powered solar cell converts light to energy, even under overcast skies

06-Jul-2018

University of British Columbia researchers have found a cheap, sustainable way to build a solar cell using bacteria that convert light to energy. Their cell generated a current stronger than any previously recorded from such a device, and worked as efficiently in dim light as in bright ...

'Tricking' bacteria into hydroxylating benzene

15-Jun-2018

Breaking carbon-hydrogen bonds is notoriously difficult in lab chemistry, yet nature does it effortlessly. Now, scientists have used E.coli bacteria to oxidize the C-H bonds in benzene to generate phenol, with a genetically inserted enzyme (cytochrome P450BM3), that originally evolved to target ...

Bacteria "brewing" tiny, high-energy carbon rings

10-Apr-2018

Caltech scientists have created a strain of bacteria that can make small but energy-packed carbon rings that are useful starting materials for creating other chemicals and materials. These rings, which are otherwise particularly difficult to prepare, now can be "brewed" in much the same way as ...

A super resolution view of chemical reactions

14-Feb-2018

Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have demonstrated, using a super resolution microscopic technique, how to follow chemical reactions taking place in very small volumes. The method of analysis developed by the Warsaw physicists in collaboration ...

Next generation solvent contributes to next generation biofuel production from biomass

05-Dec-2017

The first-generation biofuel, industrialized, ethanol, is produced from foodstuffs like maize, and thus poses great concern about a possible future shortage of food. It is therefore necessary to produce ethanol from non-food biomass like weeds, waste paper, paper cup, etc. (second-generation ...

Eating air, making fuel

27-Jun-2016

All life on the planet relies, in one way or another, on a process called carbon fixation: the ability of plants, algae and certain bacteria to "pump" carbon dioxide (CO2) from the environment, add solar or other energy and turn it into the sugars that are the required starting point needed for ...
