Effect of Different Carbon Sources on Biosurfactants’ Production by Three Strains of Lactobacillus spp.

Table 6

Yields of crude biosurfactants obtained with the different substrates.

Biosurfactants producing strains	Yield (g/L)
	Molasses	Glycerol	MRS broth
Lb. plantarum G88	2.43 ± 0.09	2.32 ± 0.19	0.30 ± 0.02
Lb. delbrueckii N2	3.03 ± 0.09	2.77 ± 0.03	0.51 ± 0.09
Lb. cellobiosus TM1	2.79 ± 0.06	2.82 ± 0.05	0.49 ± 0.07

These organic extracts are crude biosurfactants; Values are means ± standard deviation; ; a, b, c, and so on indicated column comparison; A, B, C, and so on indicated line comparison; values followed by the same lowercase letter in superscript on the same line or by the same capital letter in superscript on the same column are not significantly different () according to Duncan’s multiple range test.
