Biological activities of α-pinene and β-pinene enantiomers.
The antimicrobial activities of the isomers and enantiomers of pinene were evaluated against bacterial and fungal cells. The agar diffusion test showed that only the positive enantiomers of the α- and β-isomers of pinene were active. The minimal inhibitory concentration (MIC) and minimal microbicidal concentration (MMC) of these monoterpenes were also determined, confirming that the positive en...
متن کاملPhotochemical aerosol formation from pinene and pinene
Aerosol formation from ot-pinene and •-pinene was studied in a series of outdoor smog chamber experiments. Since a previous tudy focused on •-pinene (Pandis et al., 1991), more attention was given here to ot-pinene. The initial hydrocarbon and NO x concentrations ranged from 37 to 582 ppb and 31 to 380 ppb, respectively. The aerosol carbon yield, the fraction of the carbon initially present tha...
متن کاملMicrobial synthesis of pinene.
The volumetric heating values of today's biofuels are too low to power energy-intensive aircraft, rockets, and missiles. Recently, pinene dimers were shown to have a volumetric heating value similar to that of the tactical fuel JP-10. To provide a sustainable source of pinene, we engineered Escherichia coli for pinene production. We combinatorially expressed three pinene synthases (PS) and thre...
متن کاملThe electrochemical discrimination of pinene enantiomers by a cyclodextrin metal-organic framework.
Pinene is a family of bicyclic monoterpenes found in nature, which exhibits important applications in chemical industry and biomedicine; however, the discrimination methods used for pinene enantiomers are still rare. The alpha- and beta-pinene enantiomers were recognized and discriminated via an electrochemical method for the first time based on a cyclodextrin metal-organic framework (CD-MOF) a...
متن کاملGas-phase Β-pinene Isomerization over Acid-activated Bentonite
−− The kinetics of the gas-phase isomerization of β-pinene over an acid-activated bentonite clay has been investigated in a fixed-bed continuous flow reactor, at atmospheric pressure between 58 and 90 C. The major isomers produced were camphene, α-pinene and limonene. The reaction rates of β-pinene conversion and the apparent activation energy were determined. The kinetics of β-pinene isomeriza...
