Aerobic biodegradation of alkylphenol ethoxylates
Bioresource Technology, 2006Primary aerobic biodegradation of alkylphenol ethoxylates (APEOs) was studied using a new simple and fast porphyrin method, which did not require the extraction step. Extent of primary biodegradation of a nonylphenol ethoxylates (NP-10) was excess of 92% after 1.5 days, and reached 99% after 2 days, which was similar to the results obtained using ...

Aerobic biodegradation of selected monoterpenes
Applied Microbiology and Biotechnology, 1996Batch experiments were conducted to assess the biotransformation potential of four hydrocarbon monoterpenes (d-limonene, alpha-pinene, gamma-terpinene, and terpinolene) and four alcohols (arbanol, linalool, plinol, and alpha-terpineol) under aerobic conditions at 23 degrees C.

Aerobic biodegradation of virginiamycin in soil
Environmental Toxicology and Chemistry, 1997Abstract Aerobic biodegradation of virginiamycin was examined in six different soil types over a 64-d incubation period. The following test conditions were examined in parallel for each soil type: (1) [14C]virginiamycin at 0.5 mg carbon/50 g soil amended with 9.5 mg carbon as unlabeled glucose/50 g soil; and (2) [14C]glucose at 10 mg ...

Aerobic biodegradation of thiocyanate
Water Research, 1997Abstract The biotransformation of thiocyanate (SCN − ) and cyanate (OCN − ) in a predominantly heterotrophic, activated sludge-derived culture was investigated. Acclimation and enrichment of aerobic, thiocyanate-degrading microorganisms led to complete thiocyanate oxidation to ammonia, bicarbonate, and sulfate.

Bulletin of Environmental Contamination and Toxicology, 2009
In this paper a study was made of the biodegradation of a non-ionic surfactant, a nonylphenol polyethoxylate, in biodegradability tests by monitoring the residual surfactant matter. The influence of the concentration on the extent of primary biodegradation, the toxicity of biodegradation metabolites, and the kinetics of degradation were also determined.

The Primary Aerobic Biodegradation of Gasoline Hydrocarbons
Environmental Science & Technology, 2007We describe the primary aerobic biodegradation of an unleaded, unoxygenated, regular gasoline by inocula from unacclimated fresh and sea water, and from a domestic sewage treatment plant. Biodegradation was rapid and complete in all inocula, with an overall median "half-life", at approximately 70 ppm gasoline and low levels of inorganic nutrients, of 5

Aerobic biodegradation of cumene: An ecocore study
Environmental Toxicology and Chemistry, 1993Abstract A microcosm study was conducted to determine the mineralization and disappearance of cumene (isopropylbenzene) in an aerobic freshwater sediment/water test system. Ecocores (300 cm3) constructed of glass and Teflon® were filled with intact sediment cores and river water.

Aerobic biodegradation of 2,3- and 3,4-dichloronitrobenzene
Journal of Hazardous Materials, 2019Dichloronitrobenzenes (DCNB) are intermediates in the production of dichloroanilines, which are key feedstocks for synthesis of diuron and other herbicides. Although DCNB is a major contaminant at certain chemical manufacturing sites, aerobic DCNB biodegradation is poorly understood and such sites have not been candidates for bioremediation.

The primary aerobic biodegradation of biodiesel B20
Chemosphere, 2008We describe the primary aerobic biodegradation of a B20 fuel (20% soybean fatty acid methyl esters, 80% petroleum diesel) by unacclimated inocula from a rainwater detention pond. Biodegradation was rapid and essentially complete, with an overall median 'half-life', at approximately 100 ppm B20, of 6.8 days (n=34).
