L-(+)-Lactic acid production by Lactobacillus rhamnosus B103 from dairy industry waste
(2016-07-01)
Lactic acid, which can be obtained through fermentation, is an interesting compound because it can be utilized in different fields, such as in the food, pharmaceutical and chemical industries as a bio-based molecule for ...
Production of l (+) lactic acid by lactobacillus casei ke11: Fed batch fermentation strategies
(2021-09-01)
Lactic acid and its derivatives are widely used in pharmaceutical, leather, textile and food industries. However, until now there have been few systematic reports on fed-batch fermentation for efficient production and high ...
Synthesis and characterization of the copolymer poly(L-co-D,L lactic acid)
(Assoc Brasil PolimerosSao CarlosBrasil, 2007)
Evaluation of a new method for (L+) lactic acid purification, using ethyl ether
(2020-07-01)
The aim of the present study was to obtain high levels of fermentative L (+) lactic acid and find a better form of purification. The process was optimized by testing different compositions of the culture media, evaluating ...
High-titer and productivity of l-(+)-lactic acid using exponential fed-batch fermentation with Bacillus coagulans arr4, a new thermotolerant bacterial strain
(2018-04-01)
Bacillus coagulans arr4 is a thermotolerant microorganism with great biotechnological potential for l-(+)-lactic acid production from granulated sugar and yeast extract. The highest l-(+)-lactic acid production was obtained ...
Selective synthesis of acetaldehyde from lactic acid on acid zeolites
(Elsevier Science, 2018-03)
The gas-phase lactic acid conversion to acetaldehyde was studied on zeolites HMCM22, HZSM5 and NaZSM5 in a plug-flow fixed-bed reactor at 583. K. HMCM22 was a strong Brønsted acid zeolite that yielded 39.7% of lactic acid ...

(John Wiley & Sons IncHobokenEUA, 2003)
Profile of lactic acid within validity of full natural yogurt
(Univ Federal Ceara, Centro Ciencias Agrarias, 2016-10-01)
The objective of this study was to analyze the profile of lactic acid from three different brands of yogurt, integral type, marketed in the southwest region of Sao Paulo in the period of validity. pH and acidity analyzes ...
Chitosan and oligo(DL-lactic acid) networks: Correlations between physical properties and macromolecular configuration
(Elsevier B.V., 2016-06-14)
Aiming the obtainment of materials with useful properties for bio-applications, as thermal and mechanical (in particular flexibility), chitosan and low molecular weight poly(lactic acid) were chosen due to their biodegradability ...
Lactic acid bacteria decarboxylation reactions in cheese
(Elsevier, 2016-11)
Fermentation in cheese comprises oxidation-reduction of carbohydrates to yield organic acids, alcohols and carbon dioxide. Furthermore, organic acid and amino acid metabolism produces a series of compounds that positively ...
