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 ...

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

Bacterial degradation of poly(trans-1,4-isoprene) (gutta percha) [PDF]

Microbiology, 2007
Gutta percha, the trans-isomer of polyisoprene, is being used for several technical applications due to its resistance to biological degradation. In the past, several attempts to isolate micro-organisms capable of degrading chemically pure poly(trans-1,4-isoprene) have failed. This is the first report on axenic cultures of bacteria capable of degrading

Suppression of anthropogenic secondary organic aerosol formation by isoprene

npj Climate and Atmospheric Science, 2022
Secondary organic aerosol (SOA) represents a major fraction of atmospheric fine particles. Both biogenic and anthropogenic volatile organic compounds (VOCs) can contribute to SOA through (photo-) oxidation.
