The trend for material and energy recovery from residues along with the need to reduce greenhouse gases has led to an increased interest in the thermal exploitation of biomass and/or their wastes. Due to the enormous quantity generated every year, agro-industrial byproducts have an attractive potential to be recycled. One way to do this is by means of pyrolysis, a thermal decomposition of high molecular weight polymers into simpler compounds. In this study, we applied an autographic assay to analyze the biological effect of bio-oils produced by pyrolysis of soybean hulls. The discovery of a compound with antimicrobial activity validated this novel approach as a tool for the generation of bioactive compounds.
