Table 1. Viability loss (cell death in log cycles) of L. rhamnosus CRL 1505 after heat shock (60°C, 5 min) in different media.

Heat shock media	Components	Loss of viability (Δlog CFU ml^-1)^*
Potassium phosphate buffer	K₂HPO₄+ KH₂PO₄	-2.24 ± 0.56^b
MCM broth	Complete MCM	-0.23 ± 0.34^a
MCM1	Lactose	-1.02 ± 0.52^a
MCM2	Yeastextract +peptone	-0.20 ± 0.01^a
MCM3	Na₂HPO₄+ KH₂PO₄+ MgSO₄+ MnSO₄	-0.42 ± 0.09^a
MCM4	Na₂HPO₄+ KH₂PO₄	-1.74 ± 0.66^b
MCM5	MgSO₄+ MnSO₄	-2.85 ± 0.20^c

^*Δ log CFU ml⁻¹: difference of logCFU ml^-1 after and before heat shock.
