Title: Removal of skim milk lactose by fermentation using free and immobilized Kluyveromyces marxianus cells
Author: Lins, AD
Leao, MHMR
Abstract: Kluyveromyces marxianus CBS 6164 cells, free or immobilized in Ca-alginate (2%) beads, are able to consume more than 99% of the skim milk lactose in anaerobic conditions. In batches at 30 degreesC, the lactose consumption after 3.5 h of skim milk fermentation by 30 and 50 g free K. marxianus cells per liter was around 99 and 99.6% respectively, with an approximate conversion of lactose to ethanol and CO2 of 80%. The immobilized cells, easy to handle and showing a faster and easier separation from the fermented medium compared to the free ones, were used in more than 23 batches (cycles of re-use) without losing their activity.
