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 ...

Isoprene-degrading bacteria associated with the phyllosphere of Salix fragilis, a high isoprene-emitting willow of the Northern Hemisphere [PDF]

Environmental Microbiome, 2021
Background Isoprene accounts for about half of total biogenic volatile organic compound emissions globally, and as a climate active gas it plays a significant and varied role in atmospheric chemistry. Terrestrial plants are the largest source of isoprene,

Metabolism of key atmospheric volatile organic compounds by the marine heterotrophic bacterium Pelagibacter HTCC1062 (SAR11). [PDF]

Environ Microbiol, 2022
Summary Plants and phytoplankton are natural sources of the volatile organic compounds (VOCs) acetone and isoprene, which are reactive and can alter atmospheric chemistry.

Satellite isoprene retrievals constrain emissions and atmospheric oxidation

Nature, 2020
Isoprene is the dominant non-methane organic compound emitted to the atmosphere1–3. It drives ozone and aerosol production, modulates atmospheric oxidation and interacts with the global nitrogen cycle4–8. Isoprene emissions are highly uncertain1,9, as is

Increasing Isoprene Epoxydiol-to-Inorganic Sulfate Aerosol Ratio Results in Extensive Conversion of Inorganic Sulfate to Organosulfur Forms: Implications for Aerosol Physicochemical Properties

Environmental Science & Technology, 2019
Acid-driven multiphase chemistry of isoprene epoxydiols (IEPOX), key isoprene oxidation products, with inorganic sulfate aerosol yields substantial amounts of secondary organic aerosol (SOA) through the formation of organosulfur compounds. The extent and

Homoterpene Biosynthesis in Fungi. [PDF]

Angew Chem Int Ed Engl
The first homoterpene biosynthetic pathway in the fungal kingdom is reported. A methyltransferase–terpene cyclase pair produces a unique heptamethyl bicyclo[3.3.1]nonane homoterpene via presodorifen, demonstrating that homoterpene biosynthesis via the addition of a C1 unit to terpene diphosphate precursors prior to scaffold formation extends beyond the

Phylogenetic and Functional Diversity of Soluble Di-Iron Monooxygenases. [PDF]

Environ Microbiol
Relationships between monooxygenase substrates and products with respect to host cell physiology and biotechnology applications. ABSTRACT Monooxygenase (MO) enzymes are responsible for the oxidation of hydrocarbons and other compounds in the carbon and nitrogen cycles, are important for the biodegradation of pollutants and can act as biocatalysts for ...
