Firstly, the traditional products that can be derived from lignocellulosic xylose, including xylitol (447.88 billion USD in 2022), furfural (662 million USD in 2023), and bioethanol (46.18 billion USD in 2022), are introduced along with the current market status and latest production technologies. Then, the discussion covers the industrial development and production methods of xylo-oligosaccharides, and highlights the potential of xylonic acid, focusing on innovative whole-cell catalysis in a sealed oxygen supply-bioreactor system. Finally, other directions for efficient and high-value utilization of lignocellulosic xylose are summarized, including lactic acid, succinic acid, and 2,3-butanediol.
