Anaerobic biodegradation of saturated and aromatic hydrocarbons

Current Opinion in Biotechnology, 2001
Saturated and aromatic hydrocarbons are wide-spread in our environment. These compounds exhibit low chemical reactivity and for many decades were thought to undergo biodegradation only in the presence of free oxygen. During the past decade, however, an increasing number of microorganisms have been detected that degrade hydrocarbons under strictly ...

Thermophilic anaerobic biodegradation test and analysis of eubacteria involved in anaerobic biodegradation of four specified biodegradable polyesters

Polymer Degradation and Stability, 2013
The anaerobic biodegradability of 4 bioplastics powders (125–250 μm), polycaprolactone (PCL), poly(lactic acid) (PLA), polyhydroxybutyrate (PHB) and poly(butylene succinate) (PBS), were compared at 55 °C under aquatic conditions using our evaluation system reported previously, (the modified ISO 13975 method).

Anaerobic biodegradability of polyvinyl alcohol

Biotechnology Letters, 1993
Biodegradability of polyvinyl alcohol (PVA) under anaerobic conditions was demonstrated using anaerobic river sediments and anaerobically treated activated sludge from a sewage treatment plant. PVA having molecular weights of 2000 and 14000 was over 60% biodegraded as determined by TOC.

Anaerobic Biodegradation of Hydrocarbons

2004
Hydrocarbons are a generic group of compounds composed exclusively of hydrogen and carbon. They represent one of the most important groups of chemicals to mankind because of their natural abundance, their industrial importance, their extensive use as a primary energy source throughout the world, and their toxicity.

Anaerobic biodegradation of hexazinone in four sediments

Journal of Hazardous Materials, 2009
Anaerobic biodegradation of hexazinone was investigated in four sediments (L1, L2, Y1 and Y2). Results showed that the L2 sediment had the highest biodegradation potential among four sediments. However, the Y1 and Y2 sediments had no capacity to biodegrade hexazinone.

Modification of corn stover for improving biodegradability and anaerobic digestion performance by Ceriporiopsis subvermispora.

Bioresource Technology, 2019
Ceriporiopsis subvermispora was used to modify corn stover for improving the biodegradability and biomethane yield. Corn stover was incubated with C. subvermispora for 5-90 days then anaerobically digested.

Anaerobic Benzene Biodegradation Linked to Nitrate Reduction

Applied and Environmental Microbiology, 1999
ABSTRACT Benzene oxidation to carbon dioxide linked to nitrate reduction was observed in enrichment cultures developed from soil and groundwater microcosms. Benzene biodegradation occurred concurrently with nitrate reduction at a constant ratio of 10 mol of nitrate consumed per mol of benzene degraded.

Anaerobic biodegradability of carboxymethyloxysuccinate, a detergent builder

Journal of the American Oil Chemists' Society, 1977
Abstract and SummaryControlled amounts of C‐14 labeled trisodium car‐boxymethyloxysuccinate, an experimental detergent builder, were added to a laboratory anaerobic digester system. The daily dosages were increased incrementally from 4 to 20 ppm, dosages being held at each level for 24 days.
