“…In the cosmetic industry, lactic acid is used in the manufacture of hygiene and aesthetic products because of its moisturizing, PEER-REVIEWED REVIEW ARTICLE bioresources.com antimicrobial, and rejuvenating effects on the skin. It is also used in oral hygiene products (Castillo Martinez et al 2013).…”

Lactic acid is a naturally occurring organic acid that can be used in a wide variety of industries, such as the cosmetic, pharmaceutical, chemical, food, and, most recently, the medical industries. It can be made by the fermentation of sugars obtained from renewable resources, which means that it is an eco-friendly product that has attracted a lot of attention in recent years. In 2010, the U.S. Department of Energy issued a report that listed lactic acid as a potential building block for the future. Bearing the importance of lactic acid in mind, this review summarizes information about lactic acid properties and applications, as well as its production and purification processes.

“…Industrially preferred L-(+)lactic acid can be manufactured either by the chemical synthesis of acetaldehyde or by fermentation processes, where the latter accounts for~90% of the global lactic acid production [4]. Traditionally, lactic acid is produced by homolactic fermentation processes using pure cultures of lactic acid bacteria belonging to the genus Lactobacillus [5]. Recently, a heterolactic fermentation process with a new metabolic pathway named capnophilic (CO 2 -led) lactic fermentation (CLF) was found to be present in the hyperthermophilic marine bacterium Thermotoga neapolitana [6].…”

Adsorption Behaviour of Lactic Acid on Granular Activated Carbon and Anionic Resins: Thermodynamics, Isotherms and Kinetic Studies

Solid-liquid extraction (adsorption or ion exchange) is a promising approach for the in situ separation of organic acids from fermentation broths. In this study, a diluted concentration of lactic acid (<10 g/L) separation from a model fermentation broth by granular activated carbon (GAC) as well as weak (Reillex ® 425 or RLX425) and strong (Amberlite ® IRA-400 or AMB400) base anion exchange resins under various operating conditions was experimentally investigated. Thermodynamic analysis showed that the best lactic acid adsorption performances were obtained at a pH below the pK a value of lactic acid (i.e., 3.86) for GAC and RLX425 by physical adsorption mechanism and above the pK a value for the AMB400 resin by an ion exchange mechanism, respectively. The adsorption capacity for GAC (38.2 mg/g) was the highest, followed by AMB400 (31.2 mg/g) and RLX425 (17.2 mg/g). As per the thermodynamic analysis, the lactic acid adsorbed onto GAC and RLX425 through a physical adsorption mechanism, whereas the lactic acid adsorbed onto AMB400 with an ion exchange mechanism. The Langmuir adsorption isotherm model (R 2 > 0.96) and the pseudo-second order kinetic model (R 2~1 ) fitted better to the experimental data than the other models tested. Postulating the conditions for the real fermentation broth (pH: 5.0-6.5 and temperature: 30-80 • C), the resin AMB400 represents an ideal candidate for the extraction of lactic acid during fermentation.

“…lactis no produjo gas y fue catalasa negativo. Según Castillo-Martí-nez et al [34] la enzima catalasa, degrada el peróxido de hidrogeno (H 2 O 2 ) y para poder hacerlo requiere de un grupo porfirinico (citocromo), mismo que las BAl no pueden sintetizar; por tal motivo las BAl no poseen catalasa y esto permite identificarlas como catalasa negativas. Con respecto a la producción de gas, Agüero et al [35] comentan que la ausencia de gas de una bacteria probiótica es una de las características deseables para ser utilizada como cultivo iniciador en la industria cárnica; además de evitar problemas de gases en el organismo hospedero cuando se administra en forma oral [36].…”
