Abstract: The dynamics of microbial growth and poly(3-hydroxybutyrate) [P(3HB)] production in growth/ non-growth phases of Azhohydromonas lata MTCC 2311 were studied using a maintenance-energy-dependent mathematical model. The values of calculated model kinetic parameters were: ms1 = 0.0005 h-1, k = 0.0965, ?max = 0.25 h-1 for glucose; ms1 = 0.003 h-1, k = 0.1229, ?max = 0.27 h-1 for fructose; and ms1 = 0.0076 h -1, k = 0.0694, ?max = 0.25 h-1 for sucrose. The experimental data of biomass growth, substrate consumption, and P(3HB) production on different carbon substrates were mathematically fitted using non-linear least square optimization technique and similar trends, but different levels were observed at varying initial carbon substrate concentration. Further, on the basis of substrate assimilation potential, cane molasses was used as an inexpensive and renewable carbon source for P(3HB) production. Besides, the physico-chemical, thermal, and material properties of synthesized P(3HB) were determined which reveal its suitability in various applications.
