Forest biomass, which offers eco-friendliness and sustainability, has been highlighted due to the limitations of fossil fuel reserves and the environmental pollution they cause. Wood powder, a by-product of wood processing, is currently reprocessed for use in wood pellets, pulp, and plywood. Composed of lignocellulose, wood powder is rich in carbon, making it a potential resource for producing various high-value-added products. In this study, we explored the feasibility of wood powder extract (WPE) as a microbial culture medium. We prepared 10% (w/v) extracts using larch powder, which is abundantly produced in Korea, and performed elemental analysis. Based on the composition comparison with Minimal 9 (M9) medium, commonly used for prokaryote cultures, specific supplements were added to enhance cell growth in the WPE-based medium. Notably, WPE-based media supplemented with disodium phosphate and magnesium sulfate at concentrations of 1,000, and 120 mg/L, respectively, supported the growth of Escherichia coli, the most widely used microorganism in bio-industries. In addition, calorimetric analysis of the residual solid fraction separated after extract preparation showed 17.1 MJ/kg, meeting the standard for wood pellets in Korea. Taken together, this study demonstrates that if WPE is produced during wood powder processing, it can serve as an effective industrial microbial culture medium, while the residual solid can be utilized as a biofuel.
