“…Because lipases have certain advantages in pricing and thermal stability, many successful examples of alkenes epoxidation have been reported, including the synthesis of aliphatic alkene, cyclene, and vinyl aromatic compounds [ 12 , 13 ]. Although lipases have been isolated from various microbial genera, including Candida antarctica , Humicola sp., Pseudomonas sp., C. cylindracea , Aspergillus niger , Rhizopus chinensis , R. oryzae , and Rhizomucor mieheii [ 14 – 16 ] , the most widely used lipases are C. antarctica lipase B (CALB) [ 15 , 17 ]. This is due to its higher catalytic activity for "perhydrolysis" [ 18 ], that is, acting as the catalyst for chemoenzymatic epoxidation.…”
