Abstract
A method for measuring a relative content of Gram-negative bacteria in an active sludge, the method including: 1) breaking zoogloeas in the active sludge; 2) isolating 2-keto-3-deoxyoctonic acid (KDO) from free bacteria and cell debris; 3) performing fluorescence labeling on the isolated KDO to obtain a fluorescent derivative; and 4) isolating the fluorescent derivative by high performance liquid chromatography (HPLC) and conducting quantitative measurement by fluorescence to obtain the relative content of the Gram-negative bacteria in the active sludge.
