Supplementary Material

The supplementary information contains (a) Dilution scheme for the assay of conjugative action of Sophorolipid and cephaclor against E. coli. The dilution scheme is similar to the one represented in Table 1. (b) HPLC chromatogram of the crude sophorolipid preparation which puts some light on the relative lactone: acid percent composition of the crude sophorolipid. (c) MALDI/MS spectrum of the sophorolipid preparation in which the peaks corresponding to prominent forms of oleic acid derived sophorolipid have been marked with arrows. Along with oleic acid derived sophorolipid, few more SL forms containing other fatty acids as hydrophobic tail have been listed in a table.
