  Table 2 shows that a higher concentration of mono-rhamnolipids causes the drop to expand more and collapse faster. This verifies that presence of rhamnolipids can be indicated from drop collapse tests. The drop from sample BBa_K1688000 in BL21 from table 3 collapsed after 30 seconds and expansion of drop diameter was 120% within 5 minutes from 1 cm to 2.2 cm which indicate presence of biosurfactant. The drop from sample BBa_K1688000 in DH5α collapsed and diameter expansion of drop was 90% after 20 minutes. This indicates some presence of biosurfactants. As expected the test indicate that BBa_K1688000 was more expressed and rhamnolipid production was higher in BL21 than in DH5α as BL21 is good for protein expression. The negative controls, LB medium and un-transformed BL21 and DH5a showed very little expansion or no expansion, which is expected as they do not produce biosurfactants.

Figure 3 Gel electrophoresis. Well 1: cut BBa_K1688000, well 3: cut BBa_K1688002 and well 4: cut BBa_K1688003. All biobricks cut with EcoRI and PstI. Well 2: DNA size marker commercial 1kb. 1% w/v agarose gel stained with SyberSafe.

Table 2 and figure 6 displays data of drop expansion test with standard mono-rhamnolipids (0, 0.2, 0.4, 0.6 1 and 1.6 mg/ml). Table 3 and figure 7 displays the data of drop expansion test of LB medium, supernatant extracted from E.coli BL21 with BBa_K1688000 respectively untransformed and supernatant extracted from E.coli DH5α with BBa_K1688000 respectively untransformed.

Table 2 shows that a higher concentration of mono-rhamnolipids causes the drop to expand more and collapse faster. This verifies that presence of rhamnolipids can be indicated from drop collapse tests. The drop from sample BBa_K1688000 in BL21 from table 3 collapsed after 30 seconds and expansion of drop diameter was 120% within 5 minutes from 1 cm to 2.2 cm which indicate presence of biosurfactant. The drop from sample BBa_K1688000 in DH5α collapsed and diameter expansion of drop was 90% after 20 minutes. This indicates some presence of biosurfactants. As expected the test indicate that BBa_K1688000 was more expressed and rhamnolipid production was higher in BL21 than in DH5α as BL21 is good for protein expression. The negative controls, LB medium and un-transformed BL21 and DH5a showed very little expansion or no expansion, which is expected as they do not produce biosurfactants.
