  • Patent number: 10981975
    Abstract: The present invention describes a simple purification process for recombinant human serum albumin. The process results in highly purified protein with limited number of purification steps. The broth containing human albumin is clarified by centrifugation and microfiltration, diafiltered and captured by cation exchange chromatography by a process that allows 140-230 mg of albumin to be captured per ml of resin. Product related impurities are removed by hydrophobic interaction chromatography, optimised to allow 87-97% recovery in flow through mode. The final series of processes are so combined that there is easy transition from one step to the next with minimal interventions and adjustments. The entire process of purification is completed within two days from harvest to final product. Thus a cost-effective process with improved recovery of protein at each step is developed. The purified human serum albumin is analyzed for purity and shows physicochemical characteristics that are similar to standard albumin.

  • Patent number: 10934552
    Abstract: The disclosure herein relates to construction and application of engineering bacteria capable of secreting and expressing diacetylchitobiose deacetylase, and belongs to the technical field of fermentation engineering. Firstly, recombinant B. subtilis capable of heterologously secreting and expressing a diacetylchitobiose deacetylase gene is constructed, and a signal peptide fragment yncM is added into the recombinant vector for the first time. The signal peptide can secrete the target protein diacetylchitobiose deacetylase outside the cells of the recombinant B. subtilis, and a mutant of the 5?-end untranslated region is acquired, thereby significantly increasing the expression level of the target protein, and greatly simplifying the subsequent enzyme separation and purification steps. When the acquired diacetylchitobiose deacetylase is fermented and cultured in a fermentation medium for 50-60 h, the enzyme activity reaches a maximum of 1,548.
