Certain microbial Volatile Organic Compounds (VOCs) have been reported to enhance the growth and development of plants. The biocontrol fungi, Cladosporium cladosporioides CL-1 significantly improved the growth of tobacco seedlings in vitro when they were co-cultivated without physical contact. SPME Quadrupole GC/MS/MS revealed that CL-1 emited the volatiles α-pinene, (-)-trans-caryophyllene, te...

Limonene belongs to a group of very important intermediates used in the production of fine chemicals. This monoterpene compound can be obtained from peels of oranges or lemon which are a (biomass) waste from the orange juice industry. Thus, limonene is a renewable, easy available and a relatively cheap compound. This work presents preliminary studies on the process of limonene epoxidation over ...

Molybdenum(VI) catalysts were obtained from methanol or acetonitrile by the reaction of [MoO2(C5H7O2)2] and isonicotinoyl- nicotinoyl-based aroylhydrazones. Reactions in resulted formation mononuclear complexes [MoO2(L1–4)(MeOH)] (1a–4a), while ones provided polynuclear [MoO2(L1–4)]n (1–4). Crystals compound, [MoO2(L3)]n?H2O (3?H2O), suitable for X-ray diffraction analysis solvothermal procedur...

Limonene is the main constituent of citrus oils whose oxidation produces a set fine chemical compounds such as carvone, carveol, and limonene 1,2-epoxide. This contribution reports results experimental evaluation computational simulation carvone separation by fractional distillation from reaction mixture. Carvone was obtained over perchlorinated iron phthalocyanine supported on modified silica ...

The diastereo- and enantioselective microbial oxidation of a mixture of racemic cis/trans-chrysanthemols to the corresponding stereoisomeric chrysanthemic acids by Aspergillus species is described. Of the three microorganisms which were found capable of oxidizing racemic cis/trans-chrysanthemols, A. ochraceus ATCC 18500 showed complete enantioselectivity for (+)-stereoisomers [(+)-trans-chrysan...

Strain DCL14, which is able to grow on limonene as a sole source of carbon and energy, was isolated from a freshwater sediment sample. This organism was identified as a strain of Rhodococcus erythropolis by chemotaxonomic and genetic studies. R. erythropolis DCL14 also assimilated the terpenes limonene-1,2-epoxide, limonene-1,2-diol, carveol, carvone, and (-)-menthol, while perillyl alcohol was...
