High pressure liquid chromatography(HPLC)analysis
At 4,8,and 12 h after the start of the fermentation,1 ml samples were taken for sugar and organic acid analyses.Samples were extracted with 95%ethanol supplemented with arabinose as an
internal standard.After mixing and centrifugation,the supernatant was applied to a SepPak C18 column(Waters Corp.,Milford,MA,USA)that had been washed with methanol.Sugars were eluted with 5 ml of methanol followed by 5 ml of water.A Waters 600 HPLC system fitted with a Ion 33,Interaction 300 mm×7.8 mm column(Mandel Scientific Co.,St.Laurant,QC,Canada),using 0.005N H2SO4 at a flow rate of 0.4 ml/min mobile phase,a Waters 410 refractive index detector(Millipore,Milford MA,USA)as well as a Waters 996 photodiode array detector was used to analyse for lactose,glucose,galactose,stachyose,raffinose,sucrose,fructose,acetic acid,and lactic acid.Identified peaks were quantified using authentic standards.Samples were obtained from three inde-pendent fermentations.Values were compared to those obtained from unfermented products.
