Preparation of Microbial Media based on Hardwood Fallen Leaves

초록

This study reported the novel use of fallen leaf extract as a microbial culture media for the first time. Extract from hardwood fallen leaves (HLE) was prepared under high temperature and pressure conditions and then supplemented with specific nutrients. The growth of four industrially significant prokaryotes on the HLE-based media was measured and compared with that on enriched media (Luria-Bertani, LB). Notably, supplementing HLE with only 0.5 g of yeast extract and 1 g tryptone per liter showed a similar growth rate of Pseudomonas chlororaphis compared to standard LB media. Overall, the HLE media developed in this study offers a sustainable and cost-effective approach to microbial media production, capitalizing on the valorization of forest waste.
