“…To accomplish this task, very promising achievements could be reached by evaluating the enzymatic activities excreting by particular LAB strain in the fermentation medium and based on the obtained results adjust the deficient activities of commercial enzymes. Economical evaluation of costs of the fermentative LA production showed that the operational costs that consist of raw materials, fermentation, electrodialysis, and hydrolysis costs contribute about 77% of the total costs (Juodeikiene et al, 2015). Thus, the combination of enzymatic pretreatment with selected acid tolerant antimicrobial organisms evolving enzyme systems appears to be promising for increasing the economical efficiency of fermentative LA production.…”

“…Since its discovery, lactic acid is mainly produced by fermentation (in the form of calcium lactate), commercially exploited by the Avery Lactate Company (USA) in 1881 , . Although there are chemical production routes, they remain unused as they are more costly than present biochemical methods . Moreover, up to now, chemical routes only provide racemic mixtures, which is a major downfall for the synthesis of polylactic acid requiring maximum chiral purity or regarding its use in the food industry .…”

Dehydration of Lactic Acid: The State of The Art

et al. 2017

The dehydration of lactic acid to produce acrylic acid is a renewable alternative to the mostly used production of acrylic acid from propene. In this review, the recent developments and state of the art for the dehydration of lactic acid to acrylic acid are presented and critically commented. The most recent publications on the topic are discussed inetail with respect to the observed catalysts and process performance data. Among the different catalysts developed, three main groups can be distinguished: zeolites, sulphates, and phosphates. The latter, especially hydroxyapatites, have recently attracted the attention of academics in particular. The three families of catalysts are discussed and the recent developments and technical drawbacks in the gas phase dehydration are reported.

“…The production through fermentation is preferred because, among other advantages, the lactic acid can be produced from renewable substrates such as starchy materials (Juodeikiene et al 2015), lignocellulosic biomass (Abdel-Rahman et al 2011), food waste (Tang et al 2016), glycerol (Murakami et al 2016), microalgae (Vanthoor-Koopmans et al 2013), and sugarcane molasses . Sugarcane molasses is a potential raw material for lactic acid production.…”

Evaluation of Hybrid Short Path Evaporation to Concentrate Lactic Acid and Sugars from Fermentation

et al. 2018

Lactic acid is an important organic compound that finds various applications in the chemical, pharmaceutical, food, and medical industries. Many of these applications require lactic acid with high purity. Hybrid short path evaporation (HSPE) is a separation process well studied in the petrochemical sector that is mainly used to obtain compounds with high purity. It is also a process offering small residence time, low pressure, and environmentally friendliness. The concentration process of lactic acid was studied by using HSPE in the presence of high total reducing sugar content remaining from sugarcane molasses fermentation. In this work, the influence of operational conditions, such as evaporator temperature (86.4 °C to 153.6 °C), internal condenser temperature (7.95 °C to 18 °C), and feed flow rate (8.27 to 21.7 mL/min), on lactic acid concentration and mass percentages were evaluated. The results showed that all variables influenced the process. Mathematical models were developed for the mass percentage and concentration of the total reducing sugar in the distilled stream and for the mass percentage at residue stream. Under the best operational conditions, the concentration of lactic acid (≈ 247.7 g/L) was 2.5 times higher than the initial fermentation broth (≈ 100.1 g/L).
