KCTC13169 and KCTC13090 without acidic or enzymatic hydrolysis prior to fermentation. L. paracaseiKCTC13169 produced approximately six times more lactic acid compared with the type strain L.
casei. It was shown that the selected L. paracasei strains could utilize fructo-oligosaccharides almost completely (up to DP of 13
detectable in Jerusalem artichoke), whereas the L. casei KCTC3109
was found incapable of utilizing the fructo-oligosaccharide. Direct
lactic fermentation of Jerusalem artichoke tuber extract yielded
92.5 g/L of lactic acid with 98% conversion efficiency
