摘要

Abstract

Recombinant

Escherichia coli

BL21 is used to produce human-like collagen. The key constituents of media are optimized using response surface methodology (RSM). Before thermal induction

the highest biomass production and the lowest production of some hazardous by-products

especially acetic acid

were obtained in the media containing 0.085 mol·L

-1

glucose and 0.019 mol·L

-1

nitrogen (carbon-nitrogen ratio

4.47:1). After thermal induction

when the concentrations of glucose and nitrogen in the media were 0.065 mol·L

-1

and 0.017 mol·L

-1

respectively (carbon-nitrogen ratio

3.82:1)

the productivity of human-like collagen per cell was the highest while that of acetic acid was the lowest. The extended analysis showed that the production of lactic acid and propionic acid increased while that of some intermediate acids of the tricarboxylic acid cycle decreased if the dose of glucose increased.
