The present invention relates to a process for the separation and purification of lactic acid from a fermentation medium wherein the lactic acid is totally or partially in the form of a salt or salts. The lactic acid producing microorganisms are separated from the other components of the fermentation medium. This solution is concentrated and then acidified to a pH below or equal to 3. The acidified solution is passed over a cation exchange resin to give a fraction that has maximum of 25% lactic acid salts relative to the dry weight of the solution. This fraction is subjected to bipolar fractionating electrodialysis. The resulting lactic acid is further purified, concentrated and then recovered.

The invention discloses a method for preparing lactic acid with bipolar membrane electrodialysis technology. Lactic acid fermentation liquid passes through an electrodialyzer, which transforms contained lactates into lactic acid. The membrane tank configuration of the adopted electrodialyzer can be of two-cell type including an acid cell and a salt cell divided by an anion membrane or of three-chamber type including an acid cell, a salt cell and a base cell divided by a cation membrane and an anion membrane. For preparation, lactic acid fermentation liquid is transmitted into the salt cell and water is transmitted into the acid cell or the base cell. Under the effect of a circulating pump, the materials flow circularly with a current density of 80-160mA/cm2 at an operation temperature of 25-60 DEG C. The invention can completely supersede the prior calcium lactate acidifying technology without addition of acids for H+ supply and without production of waste acid, salt or base liquid. The transformation efficiency of lactic acid is higher than 98 percent, the recovery of lactic acid is higher than 90 percent and the current efficiency is higher than 70 percent, so the method can reduce environment pollution and lower consumption of chemical raw materials and energy and has remarkable industrial application value and environmental benefit.

We propose a procedure for the determination of lactic acid or lactate in biological fluids, which is simple and low cost with respect to the known methodologies. This procedure can be used by unskilled personnel and it can be implemented in disposable test strips and portable measure devices. The procedure is based on the photochemical reaction of lactic acid with Fe(III), which is reduced to Fe(II) when irradiated with UV light. The Fe(II), produced proportionally to the amount of lactate in the sample, is determined electrochemically or using its reaction with a colored complexing agent, such as 1,10-phenanthroline, and determined by spectrophotometry. This method is advantageous both for the low cost of the reagents employed, and for their short and long term stability.
