A genetically modified Corynebacterium for production of fucosyllactose, wherein the Corynebacterium has been modified to express a permease for lactose import, GDP-D-mannose-4,6-dehydratase (GMD), GDP-L-fucose synthase (WcaG) and fucosyltransferase (FucT) from exogenous nucleic acid sequences. The exogenous nucleic acid sequences encode a permease for lactose import and the GMD, WcaG and FucT are chromosomally integrated. The Corynebacterium additionally may comprise chromosomally integrated exogenous nucleic acid sequences for expression of phosphomannomutase (ManB) and GTP-mannose-1-phosphate guanylyltransferase (ManC). In certain embodiments, the Corynebacterium is Corynebacterium glutamicum. The Corynebacterium of the invention may be defective for functional expression of one or more glycosyltransferases involved in corynebacterial cell wall biosynthesis.
