## Abstract Lactic acid, as a versatile chemical, was purified from fermentation broth by solid phase extraction with a spherical porous poly(4‐vinylpyridine). Adsorption isotherm of lactic acid on poly(4‐vinylpyridine) was first investigated with model solutions. The factors which affect the perfo
Lactic acid fermentation is an end-product-inhibited reaction. The restriction imposed by lactic acid on its fermentation can be avoided by extractive fermentation techniques. Studies were performed by attaching an ion-exchange resin packed column with a 2-L fermentor for separation of lactic acid.
