Scientists a
step closer to developing renewable propane

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. This research is part of a programme of work aimed at
developing the next generation of biofuels.

This study provides new insight and understanding of the development of
next-generation biofuels. In this latest study, published in the journal Biotechnology
for Biofuels, scientists at the University's 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.
Their work brings scientists one step closer to the commercial production of
renewable propane, a vital development as fossil fuels continue to dwindle.

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. Efforts to find cleaner, more sustainable forms of energy as well as
using biotechnology techniques to produce synthetic chemicals are currently
being developed at The University of Manchester."

Natural metabolic pathways for the renewable biosynthesis of propane do not
exist 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. The team was
able to achieve propane biosynthesis creating a platform for next-generation
microbial propane production.

Propane has very good physicochemical properties which allow it to be
stored and transported in a compressed liquid form. While under ambient
conditions it is a clean-burning gas, with existing global markets and
infrastructure for storage, distribution and utilization in a wide range of
applications ranging from heating to transport fuel. Consequently, propane is
an attractive target product in research aimed at developing new renewable
alternatives to complement currently used petroleum-derived fuels.

Professor Scrutton comments: "This study focused on the construction
and evaluation of alternative microbial biosynthetic pathways for the
production of renewable propane. It also expands the metabolic toolbox for
renewable propane production, providing new insight and understanding of the
development of next-generation biofuels which one day could lead to commercial
production."
