Formation of Volatiles and Fattyacids of Therapeutic Importance in the Probiotic Lactobacillus Plantarum Lpcfr Adapted to Resist GIT Conditions

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.
