در این تحقیق، زئولیت nay مولکولارسیو به روش هیدروترمال تهیه شد. سپس یون های نقره در زئولیت nay با استفاده از نقره نیترات agno3و روش تبادل یونی برای تهیه زئولیتagy جایگزین گردیدند. در مرحله بعدی، نانو ذراتمنگنز دی اکسید( به عنوان مهمان) به میزان 3/9 و 8/15 درصد وزنی در زئولیت agy (به عنوان میزبان)با استفاده از محلول های mn(no3)2 و kmno4 به روش سنتز فضای محدود(css) تهیه شدند. نمونه های سنتز شده ...
BACKGROUND From fundamental studies to industrial processes, synthesis of heterologous protein by micro-organisms is widely employed. The secretion of soluble heterologous proteins in the extracellular medium facilitates their recovery, while their attachment to the cell surface permits the use of the recombinant host cells as protein or peptide supports. One of the key points to carry out hete...
