The use of the enzyme α‐acetolactate decarboxylase allows the acceleration of beer fermentation/maturation because it shunts diacetyl formation, whose elimination is the rate‐limiting step of the process. To obtain a cost reduction by using this exogenous enzyme, we propose a new process involving recoverable encapsulated α‐acetolactate decarboxylase. The performance of traditional and new processes was investigated by a modeling approach. A simple model, focused on α‐acetolactate and diacetyl… Expand
Study and Mathematical Modeling of the Production of Propionic Acid by Propionibacterium acidipropionici Immobilized in a Stirred Tank Fermentor
TLDR
The variance analysis shows that the combination of μmax and Kd parameters is the source of variation most significative, also they were found to be the most sensitive parameters of the model and an effectiveness factor was calculated in order to assess the effect of mass transfer on the overall reaction rate observed. Expand
Deacidification of grass silage press juice by continuous production of acetoin from its lactate via an immobilized enzymatic reaction cascade.
TLDR
An immobilized enzymatic reaction cascade was designed and optimized for the deacidification of grass silage press juice, thus facilitating the production of bio-based chemicals and can be applied in a multi-product biorefinery concept to take full advantage of nutrient-rich SPJ. Expand
125th Anniversary Review: Diacetyl and its control during brewery fermentation
Diacetyl is a butter-tasting vicinal diketone produced as a by-product of yeast valine metabolism during fermentation. Concentration is dependent on a number of factors including rate of formation ofExpand
Accelerated processing of beer
Publisher Summary This chapter provides an overview of accelerated processing of beer. Lagering is the most time-consuming part of the brewing process; it consists of secondary fermentation,Expand
Improving the acidic stability of Staphylococcus aureus α-acetolactate decarboxylase in Bacillus subtilis by changing basic residues to acidic residues
TLDR
This work proposed a strategy for improving the acidic stability of SaALDC in the B. subtilis host by site-directed mutagenesis and showed dramatically improved acidic stability with prolonged half-life of 3.5 h. Expand
Catalytic mechanism of acetolactate decarboxylase from Brevibacillus brevis towards both enantiomers of α-acetolactate
Acetolactate decarboxylase catalyzes both enantiomers of α-acetolactate to give a single product, (R)-acetoin, however, the reaction details are still ambiguous. In this paper, the catalyticExpand
An Improved Model for Prediction of Wort Fermentation Progress and Total Diacetyl Profile
Diacetyl is normally considered to be an off-flavor in lager beer, and its removal prolongs the overall brewing process. Here, the effects of fermentation temperature (9, 12, and 15°C), initial wortExpand
Crystallization of the FAD-independent acetolactate synthase of Klebsiella pneumoniae.
TLDR
Leucine and valine are formed in a common pathway from pyruvate in which the first intermediate is 2-acetolactate, and preliminary analysis indicates that there are four monomers located in each asymmetric unit. Expand
