Ion-exchange Resin Catalyzed Esterification of Lactic Acid with Isopropanol: a Kinetic Study [PDF]

, 2011
The kinetic behavior of esterification of lactic acid with isopropanol over an acidic cation exchange resin, Amberlyst 15, was studied under isothermal condition. Isopropyl lactate synthesized in this reaction is an important pharmaceutical intermediate.

Production of l-lactic acid by Rhizopus species

World Journal of Microbiology & Biotechnology, 1994
Of 19 Rhizopus spp. only four produced L-lactic acid in shake-flask culture. Aerobically and in the presence of a neutralizing agent, Rhizopus oryzae NRRL 395 produced the highest concentration of L-lactic acid (65 g/l) but with O2-limited growth ethanol was produced instead.

EFFECT OF NITROGEN SOURCE AND INITIAL SUGAR CONCENTRATION ON LACTIC ACID FERMENTATION OF PINEAPPLE WASTE USING L.DELBRUECKII [PDF]

, 2010
The liquid pineapple waste contains mainly sucrose, glucose, fructose and other nutrients. It therefore can potentially be used as carbon source for lactic acid fermentation.

Lactic Acid Yield Using Different Bacterial Strains, Its Purification, and Polymerization through Ring-Opening Reactions

International Journal of Polymer Science, 2014
Laboratory-scale anaerobic fermentation was performed to obtain lactic acid from lactose, using five lactic acid bacteria: Lactococcus lactis, Lactobacillus bulgaricus, L. delbrueckii, L. plantarum, and L. delbrueckii lactis.

Unstructured Models for Lactic Acid Fermentation – A Review [PDF]

, 2011
Da bi se opisao mikrobni proces, upotijebljeni su strukturirani i nestrukturirani modeli. Strukturirani modeli uzimaju u obzir strukturu, funkciju i raspored stanica, a nestrukturirani ne uzimaju fiziološka svojstva, već samo ukupnu koncentraciju stanica.

Poly-l-lactic acid for HIV-1 facial lipoatrophy: 48-week follow-up [PDF]

, 2009
OBJECTIVES: Poly-l-lactic acid (PLA) injections modestly increase objectively assessed facial thickness but not facial soft tissue volume (FSTV) over 24 weeks. The durability of this response has not been well defined objectively.

SOLID AND LIQUID PINEAPPLE WASTE UTILIZATION FOR LACTIC ACID FERMENTATION USING Lactobacillus delbrueckii [PDF]

, 2007
The liquid and solid pineapple wastes contain mainly sucrose, glucose, fructose and other nutrients. It therefore can potentially be used as carbon source for fermentation to produce organic acid.
