Effect of temperature on D-arabitol production from lactose by Kluyveromyces lactis.

D-arabitol production from lactose by Kluyveromyces lactis NBRC 1903 has been studied by following the time courses of concentrations of cell mass, lactose, D: -arabitol, ethanol, and glycerol at different temperatures. It was found that temperature is a key factor in D-arabitol production. Within temperatures ranging from 25 to 39°C, the highest D-arabitol concentration of 99.

Role of lactose on the production of D-arabitol by Kluyveromyces lactis grown on lactose.

There are remarkably few reports on D-arabitol production from lactose. Previous studies in our laboratory have shown that the osmophilic yeast Kluyveromyces lactis NBRC 1903 convert lactose to extracellular D-arabitol. The present study was undertaken to determine the participation of osmotic stress caused by lactose on D-arabitol production by K.
