Pinene is a naturally derived organic compound known as a terpene, and the paper industry generates a bunch of it as a waste product.
By inserting enzymes from trees into the bacterium, first author and Georgia Tech graduate student Stephen Sarria, working under the guidance of assistant professor Pamela Peralta-Yahya, boosted
pinene production six-fold over earlier bioengineering efforts.
Monoterpene hydrocarbons of
pinene type ([alpha]-pinene and [beta]-pinene) are well-known chemicals with antimicrobial potentials [31].
Bioconversion of alpha
pinene to verbenone by resting cells of Aspergillus niger.
But
pinene is still flammable and both limonene and
pinene have rather high boiling points that limit the rate at which they can be removed or evaporated from products.
Emissions from these devices, such as
pinene and limonene, were studied in reaction to ozone gas.
which has 1,8 Cineole, camphor, alpha
pinene and rosemarinic acid;
In addition, Lindgren funnel traps baited with the host volatile, alpha
pinene, were placed in counties adjacent to counties regulated for the introduced and federally regulated species pine shoot beetle [Tomnicus piniperda (L.) (Coleoptera: Scolytidae)] to monitor expansion of established populations of this species throughout Indiana (visit the following National Agricultural Pest Information Service (NAPIS) website for details of pine shoot beetle advancement in North America: http://www.ceris.purdue.edu/napis/states/wv/psb/wvpsb.html).
The seeds contain volatile oils including camphor and
pinene.
(One of these terpenes is
pinene, which gives pine trees their pleasant smell; terpenes also react with oxygen and ozone to form a bluish haze in forested areas.) However, hydrocarbons comprise a huge family of compounds, encompassing everything from methane (natural gas) to such plastics as polyethylene, polypropylene, and polystyrene (styrofoam).
Controls included blank runs of solvent, samples without the geraniol standard, and standards of some known floral volatiles, including alpha and beta
pinene, limonene, cineole and geraniol.
