acetic acid bacteria fermentation
How does acetic acid affect bacteria?
Acetic acid is a weak organic acid exerting a toxic effect to most microorganisms at concentrations as low as 0.5 wt%.
This toxic effect results mostly from acetic acid dissociation inside microbial cells, causing a decrease of intracellular pH and metabolic disturbance by the anion, among other deleterious effects.Acetobacter aceti is a type of bacteria.
It is a type of Gram-negative bacteria.
It is used for the large-scale production of vinegar by the conversion of ethanol to acetic acid.
Does acetic acid inhibit fermentation?
The presence of acetic acid in the fermentation media led to a significant decrease in the observed maximum cell biomass concentration.
Glucose- and xylose-specific consumption rates decreased as the acetic acid concentration increased, with the inhibitory effect being more severe for xylose consumption.
What is acetic acid bacteria in winemaking?
The family Acetobacteraceae, commonly known as acetic acid or vinegar bacteria, comprises a group of aerobic microorganisms that is often associated with the spoilage of wines through the production of acetaldehyde and acetic acid from ethanol.
