Comparing the differences in the growth rates of cells with and without plasmids in various media



Growth curves

Fig 8.1: DH5a grown in LB containing no antibiotic, LB containing Ampicillin, LB containing Chloramphenicol, LB containing both antibiotics. This clearly shows that DH5a cannot grow in medium with antibiotics.

Fig 8.4: RFP (pSB1C3) - CFP (pSB1A2) contanining cells grown in LB containing no antibiotic, LB containing Ampicillin, LB containing Chloramphenicol, LB containing both antibiotics.

Fig 8.5: All 4 strains in media without antibiotics. This graph clearly elucidates the fact that the cells which bear a plasmid tend to grow slower than those without it. The DH5a cells show considerably faster growth rate in the exponential phase compared to all the transformed cells.

(a) shows cells exposed to Bright Field.


RFP.jpg

(b) shows cells exposed to Red filter.


CFP.jpg

(c) shows cells exposed to Cyan filter.
