The production of FOS by using the glucose oxidase-expressing strain A. niger GOF-3 and the peroxidase-expressing A. niger DPOC-11. A The glucose content in the product formed by A. niger GOF-3 and DPOC-11 during the transglycosylation reaction using 40% (w/w) sucrose as substrate. A. niger ATCC 20611, A. niger ATCC 20611 plus glucose oxidase (20611 + GOX) and A. niger GOF-3 were used as the controls. B The yield of FOS produced by A. niger ATCC 20611, A. niger ATCC 20611 plus glucose oxidase (20611 + GOX), A. niger GOF-3 and A. niger GOF-3 plus DPOC-11 (GOF-3 + DPOC-11) during the transglycosylation reaction using 40% (w/w) sucrose as substrate. The products were detected by HPLC. Error bars represent the standard deviation of three independent experiments. “a/b/c” above the bars indicate the significant differences at P < 0.01
