The Effect Of Valencene Biotransformation At Different Growth Phase Of Yarrowia Lipolytica

Biotransformation is the process of transforming one organic compound from one form to another form for the purpose of reducing its persistence and toxicity by using microorganism such as yeast, fungi and bacteria etc. The biotransformation of valencene to nootkatone is getting higher demand in the...
