As with any acid, that depends entirely on its concentration. The greater the concentration (until saturation) the lower the pH.
Lactic acid is a "middle of the road" weak acid; all in equal concentrations, lactic acid is stronger than citric, weaker than acetic, and about the same as formic.
The pKa of lactic acid is 3.85, and its Ka should be 10-3.85=0.0001413. If you have not seen pKa or Ka before, that means it is a relatively weak acid since the higher the Ka, or the lower the pKa, the stronger the acid. Comparatively, acetic acid (found in vinegar) has a pKa of 4.76 and therefore is a weaker acid than lactic acid, and strong acids would have extremely high Ka's or extremely low pKa's.
The pH decreases because of lactic acid produced by Lactobacillus bulgaricus and Streptococcus thermophilus
You think probable to lactic acidosis.
Yes, sour milk is an acid. The lactic acid makes the milk acidic, milk is said to be sour when it is at a pH level of 4.3-4.5 (acidic) Yes, sour milk is an acid. The lactic acid makes the milk acidic, milk is said to be sour when it is at a pH level of 4.3-4.5 (acidic)
Yes, the build-up of lactic acid from anaerobic metabolism causes the 'burn' in muscle groups because the lactic acid has a relatively low pH that irritates the local nerve endings which is then interpreted as pain.
the decrease of the pH in sauerkraut is due to the succession of lactic and acetic acid microorganisms that grow on the brine solution making it acidic.
When organisms ferment sugars they usually produce lactic acid as a byproduct. This lactic acid production lowers the pH of the media the bacteria is grown in. The pH indicator changes the media color in response to the decreasing pH from the lactic acid production.

During anaerobic respiration, you get lactic acid in your body. Lactic acid being acid it decreases the pH of your body. After biological oxidation of glucose you get carbon bi oxide. This after dissolution gives you acid in your body.
Lactic acid in the milk.

Lactate (also known as lactic acid) and NAD+
the decrease of the pH in sauerkraut is due to the succession of lactic and acetic acid microorganisms that grow on the brine solution making it acidic.
acid as in lactic acid?
Lactic acid has two optical isomers: L-lactic acid and D-lactic acid.
