<p>A method is described for producing lactate or lactic acid from a plant extract, such as oil palm frond extract, via fermentation. In particular, the method comprises providing a fermentation medium comprising at least 25 wt. % of a plant extract containing fermentable carbohydrates, fermenting the fermentation medium by means of a lactic acid producing microorganism in the presence of a caustic magnesium salt to provide a fermentation broth containing at the most 9.5 wt. % magnesium lactate at the end of fermentation, the magnesium lactate being in soluble form during and at the end of fermentation; and recovering lactate or lactic acid from the magnesium lactate containing fermentation broth.</p> |
