additional information | the recombinant enzyme produces galactooligosaccharides from lactose by transgalactosylation. Galactooligosaccharide production increases with increasing lactose concentration, whereas the yield of galactooligosaccharides from lactose is almost constant. The final concentration of galactooligosaccharide is maximal at 80°C | Saccharolobus solfataricus | ? | - |
