Recent research in the area of bioactive carbohydrates has shown the efficiency of oligosaccharides as signal molecules in a lot of biological activities. Newly observed functions of oligosaccharides and their abilities to act as specific regulatory molecules on various organisms have been more and more described. A successful development of these bioactive molecules in future needs efficient processes for specific oligosaccharides production. To exploit them for putative industrial scale up processes, two main strategies are currently investigated: the synthesis (chemical or bioconversion processes) and the polysaccharide cleavage (chemical, physical or biological processes). Nevertheless, if new manufacturing biotechnologies have considerably increased the development of these functional molecules, the main drawback limiting their biological applications is the complexity to engender specific glycosidic structures for specific activities. In the recent years, new enzymatic reactors have been developed, allowing the automatic synthesis of oligosaccharide structures. This review focuses on the knowledge in the area of bioactive oligosaccharides and gives the main processes employed to generate them for industrial applications with challenges of monolith microreactors.
