Fed-batch Cultivation of Recombinant Escherichia coli Producing Human Interferon-γ Under Controlled Specific Growth Rate

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-...

Optimization of EnBase Fed-Batch Cultivation to Improve Soluble Fraction Ratio of α-Luffin Ribosome Inactivating Protein

Background: The increase of the protein expression via ribosomal manipulation is one of the suggested cellular mechanisms involved in EnBase fed-batch mode of cultivation. However, this system has not been implemented for cytotoxic proteins.Objectives: Here, the expression pattern of α-Luffin, a ribosome inactivation protein (RIP) with an innate toxicity,...

Optimization of secretory expression of recombinant hGM-CSF in high cell density cultivation of recombinant Escherichia coli using Taguchi statistical method

Human granulocyte macrophage colony stimulating factor (hGM-CSF) has many therapeutic applications.In this study, in order to verify the purification process, the effect of carbon source, IPTG concentration andpost-induction time on the secretion of recombinant hGM-CSF into the culture medium by recombinantEscherichia coli during high cell density cultivation were evaluated by...
