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 ...
