The cyclodextrin glucanotransferase (CGTase) from Brevibacterium sp. No. 9605 showed a broad acceptor specificity to various monosaccharides in the same way as Bacillus stearothermophilus CGTase. It specially produced a large amount of transfer products from D-mannose and L-rhamnose. The major component from the transfer products of D-mannose was found to be 4-O-α-D-glucosyl-D-mannose. Brevibacterium CGTase also formed a much greater amount of transfer products than Bacillus macerans and Bacillus stearothermophilus CGTases from 1, 3-dihydroxybenzene, 1, 3, 5-trihydroxyben-zene, 3-hydroxybenzyl alcohol, and (+) -catechin used as acceptors. The major component of the two transfer products of kojic acid was found to be kojic acid 7-O-a-D-glucoside.
