1. Introduction. Acetic acid is an important industrial feedstock, primarily produced from mineral oil or natural gas. Since oil, the most important acetic acid feedstock, is depleting, renewable resources should be taken into consideration to produce acetic acid (Li et al., 2015).Acetic acid is mainly produced by three chemical processes …

Because acetic acid is a stronger acid than water, it must also be a weaker base, with a lesser tendency to accept a proton than (H_2O). Measurements of the conductivity of 0.1 M solutions of both HI and (HNO_3) in acetic acid show that HI is completely dissociated, but (HNO_3) is only partially dissociated and behaves like a …

The produced acetic acid is released into the growth medium, where it accumulates to a maximum 5–10% in Acetobacter species and 10–20% in Komagataeibacter species (37, 38). Some genera can further oxidise the produced acetic acid to CO 2 and H 2 O, resulting in so-called acetate oxidation (overoxidation).
