Novel Isoprene-Degrading Proteobacteria From Soil and Leaves Identified by Cultivation and Metagenomics Analysis of Stable Isotope Probing Experiments

Frontiers in Microbiology, 2019
Isoprene is a climate-active gas and one of the most abundant biogenic volatile organic compounds (BVOC) released into the atmosphere. In the terrestrial environment, plants are the primary producers of isoprene, releasing between 500 and 750 million ...

Exogenous Isoprene Confers Physiological Benefits in a Negligible Isoprene Emitter (Acer monspessulanum L.) under Water Deficit

Plants, 2020
Isoprene, the main volatile released by plants, is known to protect the photosynthetic apparatus in isoprene emitters submitted to oxidative pressures caused by environmental constraints.

Measurement of isoprene nitrates by GCMS [PDF]

Atmospheric Measurement Techniques, 2016
According to atmospheric chemistry models, isoprene nitrates play an important role in determining the ozone production efficiency of isoprene; however this is very poorly constrained through observations as isoprene nitrates have not been widely ...

Inferring drivers of tropical isoprene: competing effects of emissions and chemistry [PDF]

Atmospheric Chemistry and Physics
Isoprene is the most significant non-methane hydrocarbon by total emissions and an important control on the tropospheric oxidative capacity. In the atmosphere, isoprene is oxidized by the hydroxyl radical (OH) on the order of hours depending on local OH ...

Seasonal isoprene emission estimates over tropical South America inferred from satellite observations of isoprene [PDF]

Atmospheric Chemistry and Physics
Isoprene, a volatile organic compound (VOC) emitted by plants, plays a significant role in atmospheric chemistry and climate. The Amazon rainforest is a globally relevant source of atmospheric isoprene.

Isoprene Emission in Darkness by a Facultative Heterotrophic Green Alga

Frontiers in Plant Science, 2020
Isoprene is a highly reactive biogenic volatile hydrocarbon that strongly influences atmospheric oxidation chemistry and secondary organic aerosol budget. Many phytoplanktons emit isoprene like terrestrial pants.

Assessing Ecosystem Isoprene Emissions by Hyperspectral Remote Sensing

Remote Sensing, 2018
This study examined the relationship between foliar isoprene emissions, light use efficiency and photochemical reflectance index (PRI) throughout the canopy profile and explored the contribution of xanthophyll cycle pigments versus other carotenoid ...

Can simple models predict large-scale surface ocean isoprene concentrations? [PDF]

Atmospheric Chemistry and Physics, 2016
We use isoprene and related field measurements from three different ocean data sets together with remotely sensed satellite data to model global marine isoprene emissions.

Molecular studies on Isoprene Production from Natural and Recombinant Bacteria [PDF]

Journal of Agricultural Chemistry and Biotechnology, 2017
The natural volatile hydrocarbon isoprene (2-methyl-l, 3-butadiene) is an essential chemical for polymers, drugs and rubber industry. It is produced naturally by animals, plants and bacteria. The isoprene synthase gene was identified in plants.

Deficiency and absence of endogenous isoprene in adults, disqualified its putative origin

Heliyon, 2021
Background: Isoprene (C5H8) is a clinically important breath metabolite. Although, hundreds of studies have reported differential expressions in isoprene exhalation as breath biomarker for diverse diseases, the substance couldn't enter to clinical ...
