A recombinant wine yeast strain has been constructed expressing the gene coding for a‐L‐arabinofuranosidase B from Aspergillus niger under the control of the yeast actin gene promoter. The protein is efficiently secreted by the recombinant yeast, allowing its purification and characterisation. The heterologous α‐l‐arabinofuranosidase B shows similar physico‐chemical properties to the native enzyme. The wine produced in microvinification experiments using the recombinant yeast presents the same oenological characteristics as obtained with the untransformed strain. The a‐L‐arabinofuranosidase B protein is detected throughout the fermentation.
