Biotechnological potential for degradation of isoprene: a review
Critical Reviews in Biotechnology, 2017Isoprene, the ubiquitous, highly emitted non-methane volatile hydrocarbon, affects atmospheric chemistry and human health, and this makes its removal from the contaminated environment imperative. Physicochemical degradation of isoprene is inefficient and generates secondary pollutants.

Molecular characterization and kinetics of isoprene degrading bacteria
Bioresource Technology, 2019Isoprene, the highly reactive volatile organic compound, is used as monomer for the synthesis of several useful polymers. Its extensive production and usage leads to contamination of air. Once released, it alters the atmospheric chemistry by reacting with hydroxyl radicals (OH) and nitrogen oxides (NOx) to generate tropospheric ozone.

H2O2/UV degradation kinetics of isoprene in aqueous solution
Journal of Hazardous Materials, 2000Hydrogen peroxide and UV radiation have been used in the photochemical degradation of isoprene in aqueous solutions. A kinetic study is carried out taking into account the contribution of the UV radiation reaction and the combined reaction with hydrogen peroxide.

In vitro studies on the degradation of poly( cis ‐1,4‐isoprene)
Biotechnology Progress, 2018 Cleavage of the backbone of poly(cis‐1,4‐isoprene) (IR) in solid rubber material was accomplished by the addition of partially purified latex clearing protein (Lcp1VH2) using a 200‐mL enzyme reactor.

Ozone degradation of vulcanized isoprene rubber as a function of humidity
Polymer Degradation and Stability, 2017Abstract Ozone degradation of vulcanized isoprene rubber was investigated by changing atmospheric humidity. Ozone exposure test of the vulcanized isoprene rubber was carried out with 50 pphm ozone at 40 °C, for 48 h under relative humidity (RH) between 20 and 90%, after a strain of 0.2 stretching.

The kinetics of degradation of styrene‐isoprene copolymer
Lubrication Science, 1998AbstractViscosity modifiers are one of the most important components of multi‐viscosity grade lubricants. In use, the lubricant heats up and the ingredients degrade and deplete. In an attempt to understand the thermal and thermal‐oxidative behaviour of viscosity modifiers, we have studied the effects of heat in both inert and oxidative atmospheres. The

Biotechnology Advances, 2020
Poly(cis-1,4-isoprene) rubber is a highly demanded elastomeric material mainly used for the manufacturing of tires. The end-cycle of rubber-made products is creating serious environmental concern and, therefore, different recycling processes have been proposed.

Poly-cis-isoprene Degradation by Nocardia sp. BSTN01 Isolated from Industrial Waste
Applied Biochemistry and Biotechnology, 2022The natural and synthetic rubber (NR and SR) products are made up of poly-cis-isoprene which are estimated as one of the major solid-wastes and need to be cleared through bacterial bioremediation. The present research reports isolation and characterization of a gram-positive, non-spore forming, filamentous actinomycete Nocardia sp.

Molecular ecology of isoprene degraders in the terrestrial environment [PDF]
, 2018 Isoprene (2-methyl 1, 3-butadiene) is the most abundant non-methane BVOC (biogenic volatile organic compound) released into the atmosphere. Terrestrial plants are the primary producers of isoprene and release 500-750 million tonnes of isoprene per year, to protect themselves from abiotic environmental stresses such as heat and reactive oxygen species ...
