Aerobic biodegradation of alkylphenol ethoxylates
Bioresource Technology, 2006 Primary 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 ...

Modeling Aerobic Biodegradation in the Capillary Fringe
Environmental Science & Technology, 2015 Vapor intrusion from volatile subsurface contaminants can be mitigated by aerobic biodegradation. Laboratory column studies with contaminant sources of chlorobenzene and a mixture of chlorobenzene, 1,2-dichlorobenzene, and 1,4-dichlorobenzene showed that contaminants were rapidly degraded in thin reactive zones with high biomass and low substrate ...

Aerobic biodegradation of 2,3- and 3,4-dichloronitrobenzene
Journal of Hazardous Materials, 2019 Dichloronitrobenzenes (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.

Biodegradation of Bisphenol-A in aerobic membrane bioreactor sludge
Water Science and Technology, 2013 Bisphenol-A (BPA) biodegradation was studied in a membrane bioreactor under aerobic conditions. The effects of the initial BPA concentration and initial chemical oxygen demand (COD) concentration on BPA biodegradation were investigated. The degradation process followed a first-order kinetic (more than 98% of BPA was removed) with a kinetic rate ...

Aerobic Biodegradation of Polyhydroxybutyrate in Compost
Environmental Engineering Science, 2011 Abstract Aerobic biodegradation of polyhydroxybutyrate (PHB) was investigated. Mass loss experiments were performed to determine degradation kinetics. Tributyl citrate was blended with some test samples to determine the impact of a natural plasticizer on biodegradation.

Biodegradation of Biodegradable Polymers in Mesophilic Aerobic Environments
International Journal of Molecular Sciences, 2022 Finding alternatives to diminish plastic pollution has become one of the main challenges of modern life. A few alternatives have gained potential for a shift toward a more circular and sustainable relationship with plastics. Biodegradable polymers derived from bio- and fossil-based sources have emerged as one feasible alternative to overcome ...

Biodegradation of polylactide in aerobic and anaerobic thermophilic conditions
Chemosphere, 2002 Biodegradable polymers are designed to resist a number of environmental factors during use, but to be biodegradable under disposal conditions. The biodegradation of polylactide (PLLA) was studied at different elevated temperatures in both aerobic and anaerobic, aquatic and solid state conditions. In the aerobic aquatic headspace test the mineralisation

Multi-element compound specific isotope analysis reveals aerobic biodegradation of 2,3-dichloroaniline at a complex site [PDF]
, 2022 Compound specific isotope analysis (CSIA) is an established tool for evaluating in situ transformation of organic contaminants. To date, CSIA has never been applied to understand the in situ fate of 2,3-dichloroaniline (2,3-DCA).
