Jul 11, 2022 · We investigated the hydrothermal conversion of the carbohydrates including glucose, cellulose, and starch to lactic acid using NaOH and Ca(OH)2 as alk. catalysts. Both catalysts significantly promoted the lactic acid formation. The highest yield of lactic acid from glucose was 27% with 2.5 M NaOH and 20% with 0.32 M Ca(OH)2 at 300°C for 60 s.
Jun 1, 2018 · The anaerobic acid stage fermentation under uncontrolled pH using natural undefined mixed inocula revealed that substrate containing glucose tended to form ethanol while lactic acid tended to be formed from starch fermentation.

Jan 15, 2023 · In this study, lactic acid is produced from the chemo-catalytic converting the glucose over the homogeneous ErCl 3 catalyst in an aqueous solution. The highest LaA yield of 97% was obtained at a full glucose conversion on this homogeneous catalyst at 260 °C through process optimization.
Aug 9, 2002 · A rotating fibrous-bed bioreactor (RFB) was developed for fermentation to produce L (+)-lactic acid from glucose and cornstarch by Rhizopus oryzae. Fungal mycelia were immobilized on cotton cloth in the RFB for a prolonged period to study the fermentation kinetics and process stability.
Mar 1, 2013 · Lignocellulosic materials can be used to obtain sugar solutions that may be usefully exploited for the production of lactic acid through the following steps: a) pretreatment to break down the lignocellulosic structure, b) enzymatic hydrolysis to depolymerize lignocellulose to fermentative sugars, c) sugar fermentation to lactic acid by lactic ...
