In the present study, the results demonstrated that all test
strains of fermented vegetable L. plantarum exhibited the
ability to tolerate simulated gastrointestinal tract
conditions. Their tolerances to acid and bile juices were
greatly enhanced by the addition of soybean, sesame
and Job‟s Tears. The protective capacity of the cereals
was dependent on their compositions. Soybean was
found to enhance the acid tolerance of the strains while
Job‟s Tears improved the bile tolerance. These results
suggest that these cereals could be used as vehicle for
the delivery of lactic acid bacteria as probiotic through the
human gastrointestinal tract. This finding could further
lead to the development of new symbiotic food products
with the combination of probiotic lactic acid bacteria and
cereals. Clinical trials for the potential health benefits to
the consumer should be investigated.
