  • glycerol
  • Enzymatic biodiesel production by transesterification in solvent media has been investigated intensively, but glycerol, as a by-product, could block the immobilized enzyme and excess n -hexane, as a solution aid, would reduce the productivity of the enzyme. (biomedcentral.com)
  • The two-step enzymatic process without glycerol released and solvent-free demonstrated higher efficiency and safety than enzymatic transesterification, which seems very promising for lipase-catalyzed, large-scale production of biodiesel, especially from high acid value waste oil.

  • catalyst
  • Recombinant lipase ITB1.1 from Geobacillus uzenensis local strain, isolated from Manuk hot spring , was also reported as catalyst for methylation of coconut oil. (microbiologyjournal.org)
