Method for producing lactic acid |
| abstract |
The present invention provides a method for producing lactic acid, comprising a step of recovering an aqueous solution containing calcium lactate derived from fermentation culture of a microorganism in the presence of a calcium salt and removing acetic acid. The aqueous solution containing calcium lactate in the culture solution is recovered from the non-permeate side by passing the microbial fermentation broth adjusted to pH 6-11 through a nanofilter whose polyamide is a crosslinked piperazine polyamide as a main component. And a method for producing lactic acid, comprising a step of removing acetic acid from the permeate side with high efficiency. [Selection figure] None |
