Exploring the potential of insect gut microbes for advancing renewable energy production

Abstract Insect gut microbes represent a rich source of enzymes and metabolic pathways that can be harnessed to advance renewable energy production. This review explores the potential of insect gut microbiota in the context of biomass degradation and biofuel production. Insects, particularly wood‐feeding species like termites and beetles, harbour complex microbial communities in their guts that efficiently break down lignocellulosic materials into simple sugars. These sugars can then be fermented into biofuels such as ethanol and methane. Recent research has focused on identifying key microbial species and enzymes involved in this process, as well as on engineering these microbes to enhance their efficiency and substrate specificity. Additionally, the ecological roles of these microbes in insect digestion and their potential for biotechnological applications beyond biofuel production are discussed. Overall, understanding and harnessing insect gut microbes holds great promise for advancing sustainable and renewable energy solutions.
