The first dynamic regulatory system that prevents the build-up of toxic metabolites in engineered microbes has been reported by a team of researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI). The JBEI researchers used their system to double the production in Escherichia coli (E. coli) of amorphadiene, a precursor to the premier antimalarial drug artemisinin. Using genome-wide transcriptional analysis, the JBEI researchers identified native regions of...

Many chemicals we use in everyday life are derived from fossil resources. Due to the increasing concerns on the use of fossil resources, there has been much interest in producing chemicals from renewable resources through biotechnology. Phenol is an important commodity chemical, and is a starting material for the production of numerous industrial chemicals and polymers, including bisphenol A and phenolic resins, and others. At present, the production of phenol entirely depends on the...

A major scientific breakthrough in the development of renewable energy sources and other important chemicals; The research team succeeded in producing 580 mg of gasoline per liter of cultured broth by converting in vivo generated fatty acids For many decades, we have been relying on fossil resources to produce liquid fuels such as gasoline, diesel, and many industrial and consumer chemicals for daily use. However, increasing strains on natural resources as well as environmental issues...

A simpler and faster way of producing designer bacteria used in biotechnology processes has been developed by University of Adelaide researchers. The researchers have developed a new one-step bacterial genetic engineering process called 'clonetegration', published in the journal ACS Synthetic Biology. Led by Dr Keith Shearwin, in the University's School of Molecular and Biomedical Sciences, the research facilitates faster development of designer bacteria used in therapeutic drug...

Genetic modification of bacterium results in alcohols with greater energy For the first time, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have successfully pushed nature beyond its limits by genetically modifying Escherichia coli, a bacterium often associated with food poisoning, to produce unusually long-chain alcohols essential in the creation of biofuels. "Previously, we were able to synthesize long-chain alcohols containing five carbon atoms," said...

Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
