Biodegradation of Natural Rubber: Microcosm Study

A Microcosm Study on P-Nitrophenol Biodegradation in Soil Slurry by Alcaligenes faecalis: Plackett-Burman Design

The Cyclization of Natural Rubber

The effects of solvent, temperature, time, weight percent of catalyst on the rate and mechanism of cyclization of natural rubber (NR) was studied in toluene and xylene solutions having tin tetra chloride catalyst (SnCl4). Iodometric titration show, with 8% SnCl4 (based on polymer weight) cyclization occurs, leaving 27.4% of the total unsaturation. Infrared spectra of c...

Comparative studies on crosslinked and uncrosslinked natural rubber biodegradation by Pseudomonas sp.

A comparative study on biodegradation of di-cumyl peroxide (DCP) crosslinked and uncrosslinked natural rubber by Pseudomonas sp. was carried out. Decrease in organic carbon content along with the changes in tensile strength of the treated rubber, both DCP crosslinked and uncrosslinked natural rubber, indicated rubber hydrocarbon utilization by the Pseudomonas sp. A decrease in 60.88% MPa and 41...

Microcosm Study

Abbott (1966) described microcosms as miniaturized ecosystems. Among the oldest and most specialized examples of the microcosm technique were bioassay systems, such as that found in the standard BOD determination. Abbott also noted that, due to the unpredictability and complexity of natural systems, in situ experiment results were often vague and inconclusive, and many researchers had successfu...
