University of Kent researchers build equipment slashing bacterial biofuel cost of production

In the UK, researchers from the University of Kent’s School of Biosciences have designed and built equipment that can be used to investigate bacterial biofuel production at a fraction of the cost of commercial systems. Using this technology, they also demonstrated that bacterial genetic engineering could be used to enhance biofuel production.

Commercial equipment used to study biofuel-producing bacteria can be prohibitively expensive, which prompted the team to build their own bioreactors that are accessible to most research laboratories. The researchers then used this equipment to verify that one of their genetically engineered variants of Clostridium bacteria could produce the biofuel butanol more rapidly.

These research findings, which have been published in the journals Access Microbiology and Microbial Biotechnology, reveal that a subtle change to a single gene can result in remarkable changes to how sugars are converted to biofuel products.

It is expected that this work will improve accessibility to cheaper bioreactors to stimulate wider research into biofuel production using natural and engineered bacteria.
