Degradation of synthetic oligomers by microorganisms. III. Microbial degradation of cis-1, 4-polyisoprene.

Microbial degradation of synthetic recalcitrant compounds.

Synthetic compounds, particularly highly chlorinated aromatics, comprise the bulk of the environmental pollutants that somehow must be removed from the environment. Microbial degradation of such compounds is usually very slow, making them highly persistent in nature. Some synthetic compounds, with a lower degree of chlorination are, however, biodegradable; biochemical, genetic, and molecular st...

MICROBIAL CHAIN DEGRADATION OF CHOLESTEROL BY ARTHROB ACTER SIMPLEX

Because of the importance of microbial metabolites of cholesterol as precursors in the synthesis of steroidal drugs, we decided to study the ability of Arthrobacter simplex to degrade cholesterol. Arthrobacter simplex cleaves the side chain of cholesterol in the presence of 2,2'-dipyridyl and produces 4-androstene-3,17- dione (AD) and androsta- 1,4-diene-3,17-dione(ADD). Two other intermedi...

Degradation of cis-l,4-Polyisoprene Rubbers by White Rot Fungi and Manganese Peroxidase- Catalyzed Lipid Peroxidation

6 Aerobic Degradation by Microorganisms

Physiological and chemical investigations into microbial degradation of synthetic Poly(cis-1,4-isoprene).

Streptomyces coelicolor 1A and Pseudomonas citronellolis were able to degrade synthetic high-molecular-weight poly(cis-1,4-isoprene) and vulcanized natural rubber. Growth on the polymers was poor but significantly greater than that of the nondegrading strain Streptomyces lividans 1326 (control). Measurement of the molecular weight distribution of the polymer before and after degradation showed ...
