Modelling of the Acetification Stage in the Production of Wine Vinegar by Use of Two Serial Bioreactors
(MDPI, 2020)
In the scope of a broader study about modelling wine acetification, the use of polynomial black-box models seems to be the best choice. Additionally, the use of two serially arranged bioreactors was expected to result in ...
Optimization of the Acetification Stage in the Production of Wine Vinegar by Use of Two Serial Bioreactors
(MDPI, 2021)
In the scope of a broader study about wine acetification, previous works concluded that using a single bioreactor hindered simultaneously reaching high productivities with high substrate consumption and the use of two ...
Optimization of biotechnological processes. The acetic acid fermentation. Part I: The proposed model
(Elsevier, 2009)
Vinegar is a food product of increasing significance by virtue of its widely variable origin and uses (particularly as a condiment or food preservative). The gastronomic value of vinegar has been appreciated for thousands ...
Optimization of biotechnological processes. The acetic acid fermentation. Part III: Dynamic optimization
(Elsevier, 2009)
Wine vinegar is obtained in a biotechnological process one of the crucial steps in which is the biological oxidation of the starting wine. Such a step is usually performed in a semi-continuous operation mode where a preset ...
Optimization of biotechnological processes. The acetic acid fermentation. Part II: Practical identifiability analysis and parameter estimation
(Elsevier, 2009)
In part I of this series a mathematical model for acetic acid fermentation was reported. However, no kinetic model can be complete until its equation parameters are estimated. This inevitably entails a practical identifiability ...
Structural identifiability of a model for the acetic acid fermentation process
(Elsevier, 2008)
Modelling has proved an essential tool for addressing research into biotechnological processes, particularly with a view to their optimization and control. Parameter estimation via optimization approaches is among the major ...
Modelling of wine vinegar acetification bioreactor: Global sensitivity analysis and simplification of the model
(Elsevier, 2022)
First-principles models of any process usually describe its complex underlying mechanisms using differential and algebraic equations including several unknown parameters, whose values must be normally estimated from ...
Influence of the final ethanol concentration on the acetification and production rate in the wine vinegar process
(Wiley, 2010)
BACKGROUND: The acetification process needs an overall study of the variables influencing it in order to establish their optimum values. Based on industrial experience and available literature, including a recently proposed ...
Estimating the mean acetification rate via on-line monitored changes in ethanol during a semi-continuous vinegar production cycle
(Elsevier, 2007)
A simple, fast method for estimating the mean rate of biological oxidation in a typical semi-continuous wine vinegar production cycle was developed. The method involves on-line monitoring changes in ethanol concentration ...
Modeling and optimization of acetic acid fermentation: A polynomial-based approach
(Elsevier, 2015)
Vinegar production is a typical bioprocess in the scope of the agrifood industry. Its optimization requirescareful modeling which has so far been addressed by using mainly unstructured first principles models. Because of ...
