Abstract
Abstract
The growth of microorganisms is influenced by several physico-chemical parameters that need to be controlled before starting a biological treatment plant for better process efficiency. In this study, the influence of temperature (25-40 °C), pH (4-8), and ammonium formate concentration (1.59-7.94 mM) on the growth of two yeast strains (Y.lipolytica and P.guilliermondii ) examined in a batch process. Temperature has a direct impact on the kinetic growth parameters with an activation energy (Ea) of 14.3 kcal/mol and R2 0.95 for Y.lipolytica and 12.5 kcal/mol and R2 0.97 for P.guilliermondii, what indicating a dominant biological regime. The yeast strains are acidophilic with a maximum growth pH between pH 5 and 6.
