چکیده انگلیسی
In this work the influence of acerola (Malpighiae marginata DC) pulp, at concentrations of 0, 10, 15, 25 and 30%, on mead production by Saccharomyces cerevisiae AWRI 796 was evaluated. A novel approach based on cell growth to obtain high accuracy fits for the data and to estimate optimization parameters such as Gibbs free energy was used. Fermentation was done using 107â¯cells/mL at pH 5.0 and 30â¯Â°C for up to 288â¯h. The addition of increasing concentrations of acerola pulp progressively enhanced the cell growth, with the highest cell concentration reached being â¼2.09â¯Ãâ¯108â¯cells/mL. Under these conditions, the lowest Gibbs free energy of growth was â4.81â¯kJ/mol after fermentation for 288â¯hâ¯at a pulp concentration of â¼18%. The velocity of substrate consumption was â14â¯Ãâ¯10â3 A.U./h whereas the velocity of ethanol formation was 17â¯Ãâ¯10â3 A.U./h with ethanol production of 15.2% v/v or 120.1â¯g/L.
