Thermodynamics and inhibition studies of lipozyme TL IM in biodiesel production via enzymatic transesterification

Lipase‐Mediated Synthesis of Fatty Acid Esters Using a Blending Alcohol Consisting of Methanol and 1‐Butanol

“…In accordance with previous studies in biodiesel production, Lipozyme TL IM exhibited decrease of activity at temperatures above 40 °C due to lipase inactivation by nucleophiles [24,27]. Khor et al [28] reported that a reduction of the reaction rate in the Lipozyme TL IM-catalyzed transesterification occurred at the temperatures above 40 °C. Similar results were also observed in this study.…”

Optimization and kinetic study on the synthesis of palm oil ester using Lipozyme TL IM

“…value obtained as 16.850 kJ/mol. Activation energy of 22.15 kJ/mol was reported in the production of fatty acid methyl ester (FAME) from palm oil and ethanol using Lipozyme TL IM [28]. Similar observation was also reported in the esterification of propyl gallate acid and 1-propanol by medium-bound tannase from Aspergillur niger with activation energy of 23.297 kJ/mol [29] In…”

Extraction of microalgal lipids and the influence of polar lipids on biodiesel production by lipase-catalyzed transesterification

“…Furthermore, algae harvesting in the exponential growth phase (usually when production is in continuous operation mode) will produce microalgae with more polar lipids than those harvested in the late stationary growth phase ( Microalgal oils with high FFA contents can be transesterified using acid and enzymatic catalysts; nonetheless, lipases work at lower temperatures (25-50ºC) and the subsequent separation and purification of biodiesel and glycerol is easier when using lipases (Khor et al, 2010). Some of the extracellular lipases most commonly used are from species such as Candida antarctica (Novozyme® 435), Thermomyces lanuginosus (Lipozyme® TL IM) or Rhizomucor miehei (Lipozyme® RM IM).…”
