TLDR
It was concluded that NaFA has a short biological half-life in the soils investigated and species of Pseudomonas and Fusurium capable of growth on NaFA were isolated whilst many other soil bacteria and fungi exhibited defluorinating activity when grown on an alternative organic C source.Abstract:
A range of New Zealand soils, many contaminated by sodium fluoroacetate (“Compound 1080” or NaFA) were examined for micro-organisms capable of defluorinating this animal poison. Species of Pseudomonas and Fusurium capable of growth on NaFA were isolated whilst many other soil bacteria and fungi exhibited defluorinating activity when grown on an alternative organic C source. It was concluded that NaFA has a short biological half-life in the soils investigated. Some NaFA-contaminated soils also contained species of the algae Chlorella and Chlamydomonas which were unaffected by NaFA but growth of a duck weed, Spirodela oligorrhiza , was inhibited 73% in the presence of 5 μM-NaFA.read more

The impact of fluoroacetate-bearing vegetation on native Australian fauna: a review
Laurie E. Twigg,Dennis R. King +1 more
TL;DR: Fluoroacetate is a highly toxic compound which is produced by three genera of plants in parts of south western and northern Australia, particularly the south west corner of Western Australia.

An updated review of the toxicology and ecotoxicology of sodium fluoroacetate (1080) in relation to its use as a pest control tool in New Zealand
TL;DR: Despite over 60 years of research and practical experience, the use of 1080 is still embroiled in controversy, while research efforts continue to improve its target specificity when it is used as a conservation tool or for Tb vector control.
Journal ArticleDOI
Degradation of trifluoroacetate in oxic and anoxic sediments
TL;DR: In this paper, it was shown that TFA can be rapidly degraded microbially under anoxic and oxic conditions, leading to the formation of fluoroform, a potential ozone-depleting compound with a much longer atmospheric lifetime than the parent compounds.

Microbial dehalogenation of halogenated alkanoic acids, alcohols and alkanes.
TL;DR: This chapter focuses on the catabolism of halogenated aliphatic compounds in the series: alkanoic acids, alcohols, and alkanes, and a scheme for classifying dehalogenases is provided to accommodate the current range of known enzymes and their properties.

Qingyu Wu,Wei Xiong +1 more
TL;DR: In this paper, a two-stage, autotrophic and heterotrophic cultivation of chlorella for biodiesel production is described, and high biomass is achieved to about 108 g/L with lipid content reaching about 52% of dry cell weight.

Isolation of bacteria able to metabolize fluoroacetate or fluoroacetamide.
TL;DR: This communication reports the isolation of bacteria able to use these compounds for growth and at least two occasions when accidental contamination of soil and water by fluoracetamide has occurred.

Defluorination of Monofluoroacetate by Bacteria
TL;DR: In this paper, it has been found that the defluorination of FA involved an enzyme which catalyzes the conversion of FA to glycolate and fluoride ions and that the enzyme was induced when bacteria were grown in a defined salt medium containing FA as a sole source of carbon.
