TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preparation (Claimed): The Corynebacterium transformant is obtained by introducing (A) foreign gene which encodes protein having xylooligosaccharide transporting ability, and (B) foreign gene which codes protein having beta -xylosidase activity, into host Corynebacterium. Preferred Strain: The transformant is further introduced with foreign gene which encodes protein having ATP-binding region. The host Corynebacterium has D-xylose utilization ability. The Corynebacterium transformant is C.glutamicum XYD9 (NITEP-01812). Preferred Biomolecules: The protein which has xylooligosaccharide transporting ability is transporter protein of ATP-binding cassette transporter (ABC) transporter or symporter. The foreign gene which encodes the xylooligosaccharide transporter protein comprises (a) DNA comprising a 5601 base pair sequence (SEQ ID NO: 1) fully defined in the specification or a 1377 base pair sequence (SEQ ID NO: 2) fully defined in the specification, or (b) DNA comprising base pair sequence having 90% or more homology with respect to SEQ ID NO: 1 or 2, or DNA capable of hybridizing under stringent conditions with DNA having base pair sequence of SEQ ID NO: 1 or 2. The foreign gene which encodes protein having beta -xylosidase activity, has (e) DNA comprising a 2436 base pair sequence (SEQ ID NO: 3) fully defined in the specification, or (f) DNA comprising base pair sequence having 90% or more homology with respect to base pair sequence of SEQ ID NO: 3, or DNA capable of hybridizing under stringent conditions with DNA which comprises base pair sequence complementary to SEQ ID NO: 3. The foreign gene which encodes protein having ATP-binding region comprises (a) DNA comprising a 1098 base pair sequence (SEQ ID NO: 4) fully defined in the specification, or (b) DNA comprising base pair sequence having 90% or more homology with respect to base pair sequence of SEQ ID NO: 4, or DNA capable of hybridizing under stringent conditions with DNA comprising base pair sequence complementary to SEQ ID NO: 4. The foreign gene which encodes protein having xylooligosaccharide transporting ability (ABC transporter) is derived from Corynebacterium alkanolyticum, Microbacterium testaceum, Arthrobacter phenanthrenivorans, Cellulomonas flavigena, Bifidobacterium longum, Streptomyces thermoviolaceus, or Geobacillus stearothermophilus. The foreign gene which encodes protein having xylooligosaccharide transporting ability (symporter) is derived from Clostridium acetobutylycum, Lactobacillus brevis, Bacillus subtilis, or Klebsiella oxytoca. The foreign gene which encodes beta -xylosidase is derived from C.alkanolyticum, M.testaceum, A.phenanthrenivorans, C.flavigena, B.longum, S.scabiei, C.acetobutylicum, C.cellulolyticum, L.rhamnosus, L.brevis, Paenibacillus polymyxa or G.thermoleovorans.
