Abstract Producing high value-added products from waste lipid feedstock by microbial cell factory has great advantages to minimize the pollution as well improve economic value of wasted oils and fats. Yarrowia lipolytica is a non-conventional oleaginous yeast can grow on variety hydrophobic substrates. In this study, we explored its ability synthesize α-farnesene, an important sesquiterpene, us...

Plant terpene synthase genes (TPSs) have roles in diverse biological processes. Here, we report the functional characterization of one member of the soybean TPS gene family, which was designated GmAFS. Recombinant GmAFS produced in Escherichia coli catalysed the formation of a sesquiterpene (E,E)-α-farnesene. GmAFS is closely related to (E,E)-α-farnesene synthase gene from apple, both phylogene...

The effect of ethylene regulation on a-farnesene biosynthesis in preclimateric ‘Delicious’ and ‘Granny Smith’ apples was studied using an ethylene inducer and inhibitor, a-farnesene biosynthesis precursors, and protein transcription and translation inhibitors. a-Farnesene was not detectable when internal ethylene concentrations were less than 1 ml l. Correlations between internal ethylene and a...

Zornia brasiliensis, popularly known as "urinária", "urinana", and "carrapicho", is a medicinal plant used in Brazilian northeast folk medicine as a diuretic and against venereal diseases. The aim of this study was to investigate the chemical composition and antitumor potential of the leaf essential oil of Z. brasiliensis. The essential oil was obtained by hydrodistillation using a Clevenger-ty...

HS-SPME-GC–MS analysis of the scent Dactylorhiza viridis revealed presence verbenone (28.86%), caryophyllene (25.67%), β-terpineol (9.48%), and δ-cadinene (6.94%). In romana β-ocimene (18.69%), pentadecane (18.40%), α-farnesene (14.65%), isopropyl 14-methylpentadecanoate (14.32%) were found. incarnata contained tetradecane (11.07%), (28.40%), hexadecane (19.53%), heptadecane (17.33%), α-cubenen...

The oil obtained by hydrodistillation of aerial parts of Phlomis elliptica Benth. (Labiatae), which is a rare shrub endemic to Iran, was subjected to GC-FID and GC-MS analyses. Thirty-one constituents, making up about 98.4 % of the total composition of oil, were characterized. Monoterpenes, sesquiterpenes and other compounds constituted 13.4 %, 78.9 % and 6.1 % of the essential oil, respectivel...

Phenylacetonitrile, (E)-β-ocimene, linalool, (E)-4,8-dimethyl-1,3,7-nonatriene and (E,E)-α-farnesene were identified as Japanese beetle, Popillia japonica, feeding-induced volatiles from the leaves of the giant knotweed, Fallopia sachalinensis, but not by mechanical damage. Volatile emission was also induced by treatment with a cellular signaling molecule, methyl jasmonate. These results sugges...

The relationship between ethylene and peel a-farnesene concentrations was examined by applying diphenylamine (DPA) and the ethylene analogue, propylene at varying times after harvest to superficial scald (scald) susceptible ‘Granny Smith’ apples (Malus domestica Borkh.) stored at 10°C. Delaying DPA application after harvest had no large effect on ethylene or on peel a-farnesene production. Prop...
