Kinetika Produksi Selulosa Bakteri dari Limbah Kulit Pisang

Abstract

: Banana peel waste, which is rich in nutrients and minerals, has potential to be converted into bacterial cellulose. In this research, reaction kinetics for bacterial cellulose production from banana peel was investigated. The kinetic model used in this research were fermentation kinetics method. Based on the results, it showed that bacterial cellulose production was at an exponential stage for 14 days fermentation. Fermentation time affects the bacterial cellulose production where longer fermentation time used will produce higher bacterial cellulose. Banana peel as a raw material can be used for carbon source in fermentation besides glucose. Kinetic parameters of bacterial cellulose production from banana peel according to the optimization results between data and kinetic model produced kinetics reaction parameters, such as µmax (maximum specific growth rate), ks (monod constant), kd (cell death rate constant) and m (cell maintenance constant) were 0.29/day, 2.05 g/L, 1.13/day, and 1.32/day.
