Economics of the hydrolysis of cellulosic sludge to glucose.

abstract：:Calcitriol is an important drug used for treating osteoporosis, which can be produced from vitamin D3. The current method of producing calcitriol from vitamin D3 during cultivation of microbial cells results in low yields of calcitriol and high purification costs. Therefore, in this study, the steps of cell cultivatio...
