title: Formation of volatiles and fattyacids of therapeutic importance in the probiotic Lactobacillus plantarum LPcfr adapted to resist GIT conditions.
abstract: Probiotics are the microorganisms that impart therapeutic effect and promote health by preventing various diseases. In the present work, the volatile compounds were studied in the native isolate Lactobacillus plantarum (LP) and after adaptation to resist gastro intestinal tract (GIT) conditions, which was coded as LPcfr. A number of therapeutically important compounds were present in LPcfr like butanediol (2.5%) and propionic acid (2.8%), which were not found in LP. Hexadecane (3%), butanoic acid (2%), dodecanal (2%), hexanal (7.5%), hexadecanoic acid (4%) and heptanal (6%) were found in higher concentrations in LPcfr as compared to the parent strain LP. Production of oleic acid (LP-19.2%; LPcfr -33.5%), known for reducing blood cholesterol and linoleic acid (LPcfr 2.3%), and a conjugated fatty acid known as a novel beneficial functional lipid was noticed. Linoleic acid was absent in LP. These important fatty acids were found in larger quantities in the probiotic adapted culture strain LPcfr as compared to the parent strain LP.
