Survival of Lactobacillus plantarum ZLP001 cultured in the presence of glucose, FOS (fructo-oligosaccharide), MOS (mannan-oligosaccharide), XOS (xylo-oligosaccharide), SBOS (soybean oligosaccharide), GOS (galacto-oligosaccharides), RFO (raffinose family oligosaccharide), and inulin after exposure to heat stress (65 °C; 15 or 30 min) or cold storage (4 °C; 30 or 60 days). Survival was evaluated by counting viable bacteria on MRS agar plates (mean ± SEM, n = 3). NS, MRS medium without any added sugar. The concentration of each oligosaccharides are the optimal concentrations obtained by growth assay. The concentration were 2% for glucose, FOS, SBOS, and GOS, while the concentration were 4% for MOS, XOS, RFO, and inulin.
