Resumen
Modeling of microbial growth and ammonia consumption at different temperatures was developed in the production of a polyhydroxyalkanoate(PHA) biopolymer in Pseudomona fluorescens in the range of 25–35?C. A logistic model was employed to predict accurately the microbial growthlimiting conditions of nitrogen. A new model based in a mixed mathematical equation comprising a logistic model, and a magnetic saturation modelresulted appropriate to estimate the ammonia consumption under limiting conditions. Favorable conditions for PHA production in P. fluorescenswere found at temperature of 30?C, reaching the maximum biomass concentration of 2.83 g L?1, and consuming 99.9% of the initial ammonia, toproduce 2.13 g L?1of PHA.
