Suboptimal carbon partitioning between native growth pathways and the heterologous xylitol synthesis route limits industrial productivity. Redirecting flux increases product yield per unit of glucose substrate.

Standard starch hydrolysis often results in a heterogeneous mixture with insufficient concentrations of specific malto-oligosaccharides. Increasing the purity and ratio of maltotetraose is necessary for specialized food and pharmaceutical applications requiring specific viscosity and glycemic properties.
