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 ...
Preparation of a pure inoculum of acetic acid bacteria for the selective conversion of glucose in strawberry purée into gluconic acid
(Elsevier, 2015)
Strawberry surpluses, which may account for about 20% of the whole production, could bean example of what is happening with other fruits. This surplus is largely transformed intostrawberry purée which, although is especially ...
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 ...
Gluconic acid: Properties, production methods and applications—An excellent opportunity for agro-industrial by-products and waste bio-valorization
(Elsevier, 2016)
Agro-industrial by-products and wastes pose serious, widespread problems with considerable economic and environmental consequences in developed countries. However, many of the by-products contain large amounts of sugars ...
Revalorization of strawberry surpluses by bio-transforming its glucose content into gluconic acid
(Elsevier, 2016)
Modern societies produce massive surpluses of food, by-products and wastes that increase the interest for their revalorization. This work examines the use of a culture of Gluconobac-ter japonicus CECT 8443, without pH ...
An approach for estimating the maximum specific growth rate of Gluconobacter japonicus in strawberry purée without cell concentration data
(Elsevier, 2016)
The estimation of the maximum specific growth rate ( max) for non-readily culturable bacteria, growing on complex media containing suspended solids, is a difficult task considering the important problems in obtaining ...
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 ...
Implementation of a Novel Method for Processing Proteins from Acetic Acid Bacteria via Liquid Chromatography Coupled with Tandem Mass Spectrometry
(MDPI, 2024)
Acetic acid bacteria (AAB) and other members of the complex microbiotas, whose activity is essential for vinegar production, display biodiversity and richness that is difficult to study in depth due to their highly selective ...
