Scientists reveal new technique to make biofuel from mushroom waste

Researchers at the National University of Singapore have discovered a revolutionary way to transform mushroom waste into biofuel. Despite claims to the contrary, biofuel — typically derived from food crops — is often more environmentally-destructive than it is helpful. This new technique could change that by harvesting energy from waste produced in the process of mushroom cultivation. In a study published in Science Advances , researchers explain how Thermoanaerobacterium thermosaccharolyticum (TG57), a common bacterial byproduct of mushroom cultivation, can be isolated and used to convert plant-based cellulose into biobutanol. Biobutanol is a biofuel that can be used by vehicles designed to run on gasoline. First identified in 2015, the TG57 bacterium strain has been cultivated in various forms to analyze its ability to produce biofuel in a more sustainable manner. “The production of biofuels using non-food feedstocks can improve sustainability and reduce costs greatly,” researcher He Jianzhong told Silicon Republic . “In our study, we demonstrated a novel method of directly converting cellulose to biobutanol using the novel TG57 strain. This is a major breakthrough in metabolic engineering and exhibits a foundational milestone in sustainable and cost-effective production of renewable biofuels and chemicals.” Related: Paris has a new underground – a massive farm for mushrooms and veggies Creating biofuel from waste products is a potential boon for the industry and the environment. Biobutanol holds the most promise because of its energy density, and it can be used directly, without modification, in vehicles designed to run on gasoline. Prior to the study, the high environmental and financial costs of producing biobutanol blocked it from mainstream use. However, the researchers have revealed a widely applicable, straightforward technique that does not require any significant genetic alterations of the bacterium. Someday soon, you may munch on mushrooms with the satisfaction of contributing to greener transportation and a healthier planet. Via Silicon Republic Images via Depositphotos (1)
