| Résumé | Despite known metabolic versatility of Burkholderia spp., sugar metabolism and end-product synthesis patterns in Burkholderia thailandensis have been poorly characterized. This work has demonstrated that B. thailandensis is capable of simultaneously uptaking glucose and xylose and accumulating up to 64% of its dry mass as poly(3-hydroxyalkanoate) (PHA) biopolymers, resulting in a PHA titer of up to 3.8 g L⁻¹ in shake flasks. Rhamnolipids – mainly (68–75%) in the form of Rha-Rha-C₁₄-C₁₄ – were produced concomitantly with a titer typically in the range of 0.2–0.4 g L⁻¹. Gluconic and xylonic acids were also detected in titers of up to 5.3 g L⁻¹, and while gluconic acid appeared to be back consumed, xylonic acid formed as a major end product. This first example of co-production of three products from mixed sugars using B. thailandensis paves the way for improving biorefinery economics. |
