1. A method of pretreating plant biomass comprising catalytically pretreating the plant biomass in a single-stage alkaline oxidative pretreatment process, wherein the process comprises providing a metal-ligand complex, providing a base and adding at least two oxidants to the alkaline oxidative pretreatment process to produce a catalytically pretreated plant biomass and wherein the method does not include an alkaline pre-extraction step prior to the alkaline oxidative pretreatment process.
