#Scientists a step closer to developing renewable propane (Nanowerk News) Researchers at The University of Manchester have made a significant breakthrough in the development of synthetic pathways that will enable renewable biosynthesis of the gas propane.
In this latest study, published in the journal Biotechnology for Biofuels("A microbial platform for renewable propane synthesis based on a fermentative butanol pathway"),scientists at the Universitys Manchester Institute of Biotechnology (MIB
working with colleagues at Imperial College and University of Turku, have created a synthetic pathway for biosynthesis of the gas propane.
Professor Nigel Scrutton, Director of the MIB, explains the significance of their work: The chemical industry is undergoing a major transformation as a consequence of unstable energy costs, limited natural resources and climate change.
more sustainable forms of energy as well as using biotechnology techniques to produce synthetic chemicals are currently being developed at The University of Manchester.
but scientists at the University have developed an alternative microbial biosynthetic pathway to produce renewable propane.
The team led by Nigel Scrutton and Dr Patrik Jones from Imperial College, modified existing fermentative butanol pathways using an engineered enzyme variant to redirect the microbial pathway to produce propane as opposed to butanol.
Professor Scrutton comments: This study focused on the construction and evaluation of alternative microbial biosynthetic pathways for the production of renewable propane.

#Electrical control of quantum bits in silicon paves the way to large quantum computers (Nanowerk News) A University of New south wales (UNSW)- led research team has encoded quantum information in silicon using simple electrical pulses for the first time,
Lead researcher, UNSW Associate professor Andrea Morello from the School of Electrical engineering and Telecommunications, said his team had realised successfully a new control method for future quantum computers.
Associate professor Morello said the method works by distorting the shape of the electron cloud attached to the atom,
in collaboration with the group led by UNSW Scientia Professor Andrew Dzurak. Key to the success of this electrical control method is the placement of the qubits inside a thin layer of specially purified silicon
"Associate professor Morello said. The purified silicon was provided through collaboration with Professor Kohei Itoh from Keio University in Japan n
