MATHEMATICS MODELLING OF POLYHYDROXYBUTYRATE (PHB) PRODUCTION FROM TAPIOCA. One of the technical approaches to get improvement of PHB productivity was a process simulation by using mathematical modeling. The objective of this research was to develop mathematical model which could be used to simulate fermentation of polyhydroxybutyrate production by Bacillus cereus IFO 13690 using tapi... https://jalyttlers.shop/product-category/lazy-susan/
