Lactic acid fermentation
Revision as of 13:16, 13 April 2021 by Achim Raschka (talk | contribs)
Lactic acid fermentation is a fermentation technology that converts fermentable substrates to lactic acid. It is based on a metabolic process by cells in which glucose or other fermentable sugars are converted into cellular energy and lactate, which is lactic acid in solution. This anaerobic fermentation reaction occurs in some bacteria, mainly Lactobacillales, and animal cells, such as muscle cells. For industrial processes lactic acid fermentation is used to produce lactic acid, lactides and biopolymers (polylactic acid, PLA).
Feedstock
- glucose, starch hydrolysates, sugar mixtures, 2nd generation sugar
- glycerol, plant oil
- carbon dioxide
Process description
- Primary objective
- Working principle
- Important process parameters
- Important product parameters
Products
- lactic acid, lactide, polylactic acid (PLA)
Implementation
- Maturity
- The maturity of the technology depends mainly on the feedstock that should be used. For starch hydrolysates, glucose and sugar fermentation the process it is a mature commercially running on a multi ton scale (NatureWorks, Corbion).
- For glycerol fermentation and for gas fermentation it shoulkd be at a TRL level of 5 to 6.
