Fig 2. Several isolated lactobacilli identified as GOS utilizers.
Carbohydrate utilization of lactobacilli communities isolated from the ileum (IL) and ascending colon (AC) of 21 d old piglets fed either a bovine milk-based formula (FORM), formula supplemented with GOS and PDX (F+GP). (A) Percent relative utilization (OD>0.7) of glucose, Purimune galactooligosaccharide (GOSP) or PDX. To account for isolates not capable of in vitro fermentation, utilization was normalized to maximum number of isolates capable of utilizing glucose as a sole carbon source. (B) Maximum optical density (595 nm) of Lactobacilli sp. when GOSP is supplemented as a sole carbon source. Colored bar indicates the mean maximum optical density. Not all Lactobacillus sp. were detected in each treatment or location.
