LAB, lactic acid bacteria; CFU, colony-forming units; TTA, total titratable acidity; G2, galactobiose; G3, galactotriose; MP, milk permeate; MPLUHS29, fermented with LUHS29 (P. acidilactici); MPNF, unfermented; GOS, galactooligosaccharides; nd, not determined. Data are represented as means (n = 3) ± SD. a–b Means with different letters in column are significantly different (p ≤ 0.05).
