Application of a fed-batch bioprocess for the heterologous production of hSCOMT in Escherichia coli.

Efficient Process Development of Recombinant Human Granulocyte Colony-Stimulating Factor (rh-GCSF) Production in Escherichia coli

Background: The protein hormone granulocyte colony-stimulating factor (GCSF) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. Methods: An efficient process was developed for heterologous expression of human GCSF in E. coli BL21 (DE3). The feeding rate was adjusted to achieve the maximum attainable specific growth rate under crit...

Scale-up bioprocess development for production of the antibiotic valinomycin in Escherichia coli based on consistent fed-batch cultivations

BACKGROUND Heterologous production of natural products in Escherichia coli has emerged as an attractive strategy to obtain molecules of interest. Although technically feasible most of them are still constrained to laboratory scale production. Therefore, it is necessary to develop reasonable scale-up strategies for bioprocesses aiming at the overproduction of targeted natural products under indu...

Physiological and Morphological Changes of Recombinant E. coli During Over-Expression of Human Interferon-g in HCDC

The objective of this research was to investigate the influence of the over-expression of recombinant interferon-g during high cell density cultivation on cellular characteristics of recombinant E. coli. Batch and fed-batch culture techniques were employed to grow Escherichia coli BL21 for production of human gamma-interferon in pET expression system. Final cell densities in batch and fed-batch...

media and specific growth rate selection for high-cell-density cultivation of recombinant escherichia coli producing hGM-CSF in fed-batch process

مقایسه کمی تولید پروتئین نوترکیب انتهای کربوکسیل نوروتوکسین بوتولینوم A در کشت‌های ناپیوسته و ناپیوسته خوراک‌دهی‌شده باکتری اشرشیا کلی

Background and purpose: The 50 KDa protein (50 µg) in carboxylic domain of the neurotoxin heavy chain (BoNT/A-Hc) recognizes surface receptors on target neurons and this fragment contains the principle protective antigenic determinants. Recently, this fragment has been used as a recombinant vaccine candidate for botulism. The study aimed to compare the evaluation of BoNT/A-Hc production in fed-...
