D-xylose, D-fructose, D-sorbitol, maltose, sucrose, starch and inulin are found to be precursors of nigeran synthesis although hydrolysates of nigeran exclusively contain glucose and in case of starch and inulin traces of fructose

synthesis of oligosaccharides synthesized from a mixture of maltoheptaose and maltose, several types of oligosaccharides with degree of polymerization 2 to 8 containing alpha-D-Glcp-(1,6)-maltoheptaose are formed at 15°C, LC-MS and methylation product analysis, overview. Most of these compounds consist of alpha-(1,4) linkages in the main chain and alpha-(1,6) linkages at the non-reducing ends. However, when the reaction mixture is incubated for 96 h, most of these products were converted into oligosaccharides with DP2 to DP5 consisting of only alpha-(1,6) linkages. Thus, the transglucosidase rapidly transfers glucosyl residues to maltooligosaccharides, and gradually hydrolyzes both alpha-(1,4) linkages and alpha-(1,6) linkages at the non-reducing end, and transforms these into smaller molecules of mainly alpha-(1,6) linkages
