Biodegradation of polyester polyurethane by endophytic fungi.
Bioremediation is an important approach to waste reduction that relies on biological processes to break down a variety of pollutants. This is made possible by the vast metabolic diversity of the microbial world. To explore this diversity for the breakdown of plastic, we screened several dozen endophytic fungi for their ability to degrade the synthetic polymer polyester polyurethane (PUR). Sever...
متن کاملBiodegradation of ether pollutants by Pseudonocardia sp. strain ENV478.
A bacterium designated Pseudonocardia sp. strain ENV478 was isolated by enrichment culturing on tetrahydrofuran (THF) and was screened to determine its ability to degrade a range of ether pollutants. After growth on THF, strain ENV478 degraded THF (63 mg/h/g total suspended solids [TSS]), 1,4-dioxane (21 mg/h/g TSS), 1,3-dioxolane (19 mg/h/g TSS), bis-2-chloroethylether (BCEE) (12 mg/h/g TSS), ...
متن کاملBiodegradation of organic pollutants by halophilic bacteria and archaea.
Hypersaline environments are important for both surface extension and ecological significance. As all other ecosystems, they are impacted by pollution. However, little information is available on the biodegradation of organic pollutants by halophilic microorganisms in such environments. In addition, it is estimated that 5% of industrial effluents are saline and hypersaline. Conventional nonextr...
متن کاملBacterial promoters triggering biodegradation of aromatic pollutants.
Unraveling the complex transcriptional regulation of bacterial catabolism of aromatic pollutants is a prerequisite for engineering efficient biological systems for many biotechnological applications. A first level of regulation relies on specific regulator-promoter pairs. There have been new insights into the molecular mechanisms that regulatory proteins use to sense a given signal and to activ...
متن کاملBiodegradation of new series of aliphatic copolyesters by fungi
Biodegradable aliphatic random copolyesters poly(butylene succinate-co-butylene adipate), PBSA and poly(butylene succinate-co-butylene azelate), PBSAz were synthesized from 1,4 butane diol, succinic acid and adipic acid/azelaic acid through direct melt polycondensation with Titanium Tetra isopropoxide (TTiPO) as a catalyst. These polyesters were characterized by Viscosity measurements, 1H NMR s...
