Abstract
The maximal production of recombinant HIV1 gp41 by E. coli was examined in optimal culture condition and medium compositions. The culture condition such as growth, initial medium pHs, IPTG concentrations, induction times, temperature (0.5 OD, 7.6, 0.75â¯mM, 4.6â¯h, 32â¯Â°C respectively), and yeast extract (7.51â¯g/l), tryptone (7.26â¯g/l), glucose (2.45â¯g/l), NaCl (20.40â¯g/l), betaine (10.41â¯mM) and ampicillin (71.23â¯Î¼g/ml) was optimized using statistical experimental design and response surface method (RSM). One of the main popular methods to attain high cell density in fed-batch culture is by controlling the nutrient feeding, which is often necessary for high yield in protein (0.63-0.72â¯mg/l) and cell (1.7-2â¯g/l) of the desired product in four litter fermentations.
