Oct 12, 2020 · Starchy biomass and sugar plant wastes (malt, molasses and sugar beet juice) Lactic acid can be produced from sugar plant wastes (molasses and sugar beet juice), starchy, and lignocellulosic biomasses ( Figure 2 ). Pathways of lactic acid production from pentose sugars obtained from lignocellulose hydrolysate.
Feb 24, 2023 · Direct conversion of starch to lactic acid using lactic acid-producing fungi is cost-effective, unlike the conversion of starch or cellulose to sugar, which consumes energy during liquefaction or saccharification .

Lactic acid, or 2-hydroxypropionic acid (CAS 50-21-5), is the most widely occurring hydroxycarboxylic acid (Datta and Henry 2006). It is a natural organic acid with a long history of applications in the food, pharmaceutical, textile, and chemical industries (Ouyang et al. 2013). In recent years, the demand for lactic acid has increased considerably...
The lactic acid molecule is found naturally in plants, microorganisms, and animals, and may also be produced by the fermentation of carbohydrates or by chemical synthesis from coal, petroleum products, and natural gas. Industrially, lactic acid can be produced by chemical synthesis or by fermentation. Figure 2 shows the two main processes of lactic...
According to this review, it is possible to observe the importance of lactic acid because of its widespread use and applications. The literature reports many lactic acid applications, such as cosmetics, pharmaceutical products, chemistry, food, and more recently in the medical area. The largest demand is in food and polymers application. Lactic aci...

Sep 1, 2023 · Therefore, this study investigated the feasibility of lactic acid production from carbohydrate-enrich corn starch, tapioca starch, potato starch, and rice starch with inexpensive nitrogen-rich agro-industrial waste of corn steep liquor, palm kernel cake, and soybean meal.
Apr 7, 2010 · The results of this study suggested that a fed-batch operation with a starch-controlled feeding strategy could enhance lactic acid productivity, which would make commercial lactic acid production directly from starch more feasible.
