Using ‘wired microbes’ to generate electricity from sewage

By Damir Beciri
23 September 2013

microbial-battery-1Exoelectrogenic microbes are organisms evolved in airless environments which developed the ability to react with oxide minerals to create biological fuel needed for their survival. Although several research groups tried different approaches to tap into this source of energy since the turn of millennium, efficient use of these microbes as bio-generators proved to be challenging…. »

Spiber Qmonos – a tough and lightweight artificial spider silk

By Maja Bosanac
2 Comments14 July 2013

spiber-qmonos-1A Japanese startup called Spiber Inc. has created an artificial spider silk using synthesized genes which persuade bacteria to produce fibroin, a structural protein found in spider silk. Researchers have developed technologies to cultivate these bacteria efficiently and weave the fibroin into fabric. The protein derived from fibroin has been given the name “QMONOS” (from… »

23 April 2013

bees-tubes-1When blossoms and leaves wane and turn black, it is usually too late to fight off the disease which attacks the plant. Fire blight is a plant disease which strikes fruit trees such as apple and pear trees. Clearing the affected trees was often the only chance left before it takes over the entire orchard…. »

Using bacteria mechanism to create bonds

By Damir Beciri
One Comment26 February 2012

pnas-oxford-university-spytag-spycatcher-1Researchers from the University of Oxford managed to create a bio-inspired superglue with unmatched performance by engineering an unusual protein from Streptococcus pyogenes – a type of bacteria that can cause mild infections as well as some life-threatening diseases. The modified protein enables sticking molecules, proteins or enzymes together to build new structures on the… »

New biosensors arise from glowing bacteria synchronization research

By Damir Beciri
One Comment19 December 2011

glowing-bacteria-microfluidic-chipBiologists and bioengineers at UC San Diego have created a living neon sign composed of millions of bacterial cells that periodically fluoresce in harmony like blinking light bulbs. By utilizing the same method they used to create the flashing signs, the researchers managed to make a simple bacterial sensor that could be used to detect… »

Increasing phytoremediation with bacteria

By Damir Beciri
2 Comments2 December 2011

champignons-petroleA multidisciplinary team of researchers from Canada is looking for ways to improve phytoremediation – a process where plant matter is used for decontamination. They use bacteria to stimulate faster growth capacity of certain plants and microscopic mushrooms which act as decontamination units. The researchers expect that these decontamination units will be used at various… »
