All the strains showed a similar behavior and could
grow until 1.0% of bile salt and their growth
was reduced between 1.0 to 3.0% of bile salt.
No correlation was found between sodium chloride
tolerance and bile salts tolerance (p 0.05), so
these two factors are independent for the strains
tested. Results obtained with the two Lactobacillus
plantarum strains agreed with what other researchers
reported in similar conditions for other L. plantarum
strains. Zago et al. (2011) analyzed the absorbance
(600 nm) of 27 L. plantarum strains up to bile
salt concentrations of 1.0% at 371C after 24 h
and concluded that the bile salt resistance was
variable and depended of the strain tested. A
similar conclusion was reported by Jamali et al.
(2011). Moreover, the high bile salt tolerance of
halotolerant lactobacilli analyzed is consistent with
previously reported for other potential probiotic strains
(Vinderola and Reinheimer, 2003) who found a
higher survival of potential probiotic strains against
lactic acid starter. So that, probiotic and potential
probiotic halotolerant lactobacilli could survive under
the maximum stress conditions present in the small
intestine when excessive fat is consumed in the diet.
