Scientists Stored a GIF in DNA of Living Bacteria

A team of scientists from Harvard University was able to successfully introduce a GIF into the genome of live Escherichia coli bacteria.

The GIF, an image with movement of a horse and its rider in black and white, was divided into 5 frames of which each pixel was encoded into nucleotides and placed into the DNA of the bacterium, using the… 163 more words

Bio-based p-xylene oxidation into terephthalic acid by engineered E. coli

Metabolically engineered Escherichia coli (E. coli)is developed to biologically transform pX into TPA, a chemical necessary in the manufacturing of polyethylene terephthalate (PET). This biocatalysis system represents a greener and more efficient alternative to the traditional chemical methods for TPA production.The researchers utilized a metabolic engineering and synthetic biology approach to develop a recombinant microorganism that can oxidize pX into TPA using microbial fermentation. 72 more words
