Optimization of bacterial cellulose production by using response surface methodology(RSM)effect of PH,temperature and concentration of fermentation medium

Bacterial cellulose is a type of biopolymer that produced by Acetobacter xylinum in high purity,high water holding capacity,good mechanical strength, elasticity and high crystallinity.In this research,pineapple residue was used as the carbon sources to replace the pure carbon sources as the substrat...
