Biodegradation of Pesticides at the Limit: Kinetics and Microbial Substrate Use at Low Concentrations.

Johannes Wirsching et al.

Frontiers in microbiology, 11, 2107-2107 (2020-09-29)

The objective of our study was to test whether limited microbial degradation at low pesticide concentrations could explain the discrepancy between overall degradability demonstrated in laboratory tests and their actual persistence in the environment. Studies on pesticide degradation are often

Enhanced host-guest electrochemical recognition of herbicide MCPA using a β-cyclodextrin carbon nanotube sensor.

V Rahemi et al.

Talanta, 99, 288-293 (2012-09-13)

An electrochemical sensor for the determination of the chlorophenoxy herbicide MCPA has been developed, based on a combination of multi-walled carbon nanotubes with incorporated β-cyclodextrin and a polyaniline film modified glassy carbon electrode. The proposed molecular host-guest recognition based sensor

A review of potential human carcinogenicity of the chlorophenoxy herbicides MCPA, MCPP, and 2,4-DP.

G G Bond et al.

British journal of industrial medicine, 50(4), 340-348 (1993-04-01)

For the purpose of assessing the human carcinogenic potential of the chlorophenoxy herbicides MCPA, MCPP, and 2,4-DP, the relevant epidemiological and toxicological evidence is reviewed. These compounds have not produced tumours in animal studies conducted under current test guidelines, giving

Comparing metabolic functionalities, community structures, and dynamics of herbicide-degrading communities cultivated with different substrate concentrations.

Erkin Gözdereliler et al.

Applied and environmental microbiology, 79(1), 367-375 (2012-11-06)

Two 4-chloro-2-methylphenoxyacetic acid (MCPA)-degrading enrichment cultures selected from an aquifer on low (0.1 mg liter(-1)) or high (25 mg liter(-1)) MCPA concentrations were compared in terms of metabolic activity, community composition, population growth, and single cell physiology. Different community compositions

Protozoan predation in soil slurries compromises determination of contaminant mineralization potential.

Nora Badawi et al.

Environmental pollution (Barking, Essex : 1987), 170, 32-38 (2012-07-06)

Soil suspensions (slurries) are commonly used to estimate the potential of soil microbial communities to mineralize organic contaminants. The preparation of soil slurries disrupts soil structure, however, potentially affecting both the bacterial populations and their protozoan predators. We studied the
