Biocatalytic synthesis of monoterpene esters – A review study on the phylogenetic evolution of biocatalysts

Global trends and future prospects of lactic acid production from lignocellulosic biomass

“…Cluster #1, denoted as “catalytic conversion” (silhouette score = 0.902; 330; 2012), the second-largest cluster with 330 publications, underscores the increasing attention towards the direct catalytic conversion of LCB to LA and its derivatives, signifying a relatively recent area of significant interest. Chemical catalysis can be broadly categorized into photochemical catalysis, 71 biocatalysis, 72 acid–base catalysis, metal catalysis, 73 and more. It typically involves acid–base or metal catalysis to transform LCB into LA under specific temperature, pressure, and atmospheric conditions.…”

Discovery, characterization and mechanism of a Microbacterium esterase for key d-biotin chiral intermediate synthesis

“…Due to the difficulty and cost involved in obtaining esterases from animals and plants, microbial sources have become the predominant choice for industrial applications. Microorganisms such as Candida , Pseudomonas , Actinobacteria and Aspergillus niger have been extensively explored as potential sources of esterases (Cieśliński et al 2007 ; Jeon et al 2009 ; Ma et al 2013 ; Papanikolaou et al 2023 ; Staudt et al 2022 ; Wei et al 2013 ; Zhang et al 2014 ).…”

Response surface methodology for optimization of enzymatic acylation of (R)‐(‒)‐linalool application to essential oils

“…It is utilized generally in perfumery and many flowery fragrance compositions for fruity‐fresh odours such as neroli, lavender, and lily of the valley 3 . Linalool was included in the list of class “A” substances due to its usefulness as primal matter for the synthesis of high‐value added compounds, such as their ester derivatives, 4,5 especially the acetate form 6,7 . Unlike linalool, linalyl acetate is also used as safe flavour adjuvants in food industries due to their high stability and low toxicity and in addition to their pharmacological properties such as antioxidant, antibacterial, or anti‐inflammatory activities 8–10 …”

“…3 Linalool was included in the list of class "A" substances due to its usefulness as primal matter for the synthesis of high-value added compounds, such as their ester derivatives, 4,5 especially the acetate form. 6,7 Unlike linalool, linalyl acetate is also used as safe flavour adjuvants in food industries due to their high stability and low toxicity and in addition to their pharmacological properties such as antioxidant, antibacterial, or anti-inflammatory activities. [8][9][10] Linalool exists naturally as two isomeric forms, the 3R-(−)-linalool called licareol (odour threshold 0.8 ppb) that has a lavender or lily-of-the-valley odour and the dextrorotatory isomer is 3 S-(+)-linalool called coriandrol (odour threshold 7.4 ppb) that has a herbaceous and musty green smell 11 Licareol is the most common isomeric form; both enantiomers are available in nature, and the stereoisomeric composition of this alcohol influences the olfactory properties of the essential oils containing it.…”
