Biosurfactant-Producing Lactobacilli: Screening, Production Profiles, and Effect of Medium Composition

Table 2

Surface tension values (mN m⁻¹) obtained from the biosurfactant extraction with PBS for the different strains during 8 h (the control surface tension (PBS) was 72.0 mN m⁻¹). Results are expressed as means ± standard deviations of values from triplicate experiments.

Strain	Surface Tension (mN m^−1)

Lactobacillus coryniformis ssp. torquens CECT 25600	72.0±0.1	70.3±0.6	68.1±0.5	67.0±0.4
Lactobacillus paracasei ssp. paracasei A20	72.0±0.1	51.4±0.4	50.2±0.3	50.0±0.4
Lactobacillus plantarum A14	72.0±0.1	60.7±0.5	60.6±0.6	59.9±0.4
Leuconostoc mesenteroides A4	72.0±0.1	70.8±0.3	69.7±0.4	69.6±0.4
