Marine isoprene production and consumption in the mixed layer of the surface ocean – a field study over two oceanic regions [PDF]

Biogeosciences, 2018
Parameterizations of surface ocean isoprene concentrations are numerous, despite the lack of source/sink process understanding. Here we present isoprene and related field measurements in the mixed layer from the Indian Ocean and the eastern Pacific ...

Isoprene Oxidation by the Gram-Negative Model bacterium Variovorax sp. WS11

Microorganisms, 2020
Plant-produced isoprene (2-methyl-1,3-butadiene) represents a significant portion of global volatile organic compound production, equaled only by methane.

Synthesis and characterization of isoprene oligomers to compare different production chemical processes

Polímeros, 2019
Three methods to obtain isoprene oligomers were evaluated: chemical degradation of non-vulcanized coagulated natural rubber; chemical degradation of natural rubber latex; and oligomerization of the isoprene monomer.

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 ...

Sphingopyxis sp. Strain OPL5, an Isoprene-Degrading Bacterium from the Sphingomonadaceae Family Isolated from Oil Palm Leaves

Microorganisms, 2020
The volatile secondary metabolite, isoprene, is released by trees to the atmosphere in enormous quantities, where it has important effects on air quality and climate.

Identification and characterisation of isoprene‐degrading bacteria in an estuarine environment [PDF]

Environmental Microbiology, 2017
Summary Approximately one‐third of volatile organic compounds (VOCs) emitted to the atmosphere consists of isoprene, originating from the terrestrial and marine biosphere, with a profound effect on atmospheric chemistry.

Formaldehyde production from isoprene oxidation across NO_x regimes [PDF]

Atmospheric Chemistry and Physics, 2016
The chemical link between isoprene and formaldehyde (HCHO) is a strong, nonlinear function of NOx (i.e., NO + NO2). This relationship is a linchpin for top-down isoprene emission inventory verification from orbital HCHO column observations. It is also a

Global and regional impacts of land cover changes on isoprene emissions derived from spaceborne data and the MEGAN model [PDF]

Atmospheric Chemistry and Physics, 2021
Among the biogenic volatile organic compounds (BVOCs) emitted by plant foliage, isoprene is by far the most important in terms of both global emission and atmospheric impact. It is highly reactive in the air, and its degradation favours the generation of

Gene probing reveals the widespread distribution, diversity and abundance of isoprene-degrading bacteria in the environment

Microbiome, 2018
Background Approximately 500 Tg of isoprene are emitted to the atmosphere annually, an amount similar to that of methane, and despite its significant effects on the climate, very little is known about the biological degradation of isoprene in the ...

Improved global modelling of HO_x recycling in isoprene oxidation: evaluation against the GABRIEL and INTEX-A aircraft campaign measurements [PDF]

Atmospheric Chemistry and Physics, 2010
Stimulated by recent important developments regarding the oxidation chemistry of isoprene, this study evaluates and quantifies the impacts of different mechanism updates on the boundary layer concentrations of OH and HO2 radicals using the IMAGESv2 ...
