Glucose was used as acceptor to obtain small chain oligossaccharides from sucrose using dextransucrase from Leuconostoc mesenteroides NRRL B-512F. Better conditions for the synthesis of the oligosaccharides were obtained using experimental design and response surface methodology. Yield of oligosaccharides was increased from 5% to 45% following an increase in both sucrose and glucose/sucrose concentrations, from 58 g/l to 142 g/l and from 0.02 to 0.18, respectively. Molecular weight increased from 2800 to 4500 daltons with a temperature shifting from 10 degrees C to 30 degrees C.
