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

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...

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-...

Production of Recombinant Human Granulocyte-Colony Stimulating Factor by Pichia pastoris

Human granulocyte-colony stimulating factor (hG-CSF) cDNA was expressed in the methylotrophic yeast Pichia pastoris under the control of the alcohol oxidase (AOX1) promoter. An expression vector for hG-CSF secretion was constructed using vector pPIC9. Higher levels of hG-CSF was obtained using a P. pastoris Mut+ (methanol utilization fast) phenotype. The effects of environmental factors such as...

Maximizing Production of Human Interferon-γ in HCDC of Recombinant E. coli

Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....
