Herbicides and Soil Microorganisms
CRC Critical Reviews in Microbiology, 1976The production and usage of herbicides have increased dramatically in recent years. Consequently there is growing concern about the effects of these chemicals on the environment, particularly the possible long-term effects on soil fertility which may result from disturbance of the soil microflora.

This handbook covers the most commonly used techniques for measuring plant response to biotic and abiotic stressing factors, including: in vitro and in vivo bioassays; the study of root morphology, photosynthesis (pigment content, net photosynthesis, respiration, fluorescence and thermoluminiscence) and water status; thermal imaging; the measurement of

Degradation of carbaryl by soil microorganisms
Archives of Environmental Contamination and Toxicology, 1977Four days after carbaryl-naphthyl-1-14C was mixed with soil from a field treated 6 months previously with 4 lb/A of the same insecticide, only 28% of the radiocarbon remained. Approximately 90% remained in soils with no history of pesticide applications.

Dieldrin: Degradation by Soil Microorganisms
Science, 1967An attempt was made to discover microorganisms that degrade dieldrin, an extremely stable chlorinated hydrocarbon insecticide. Examination of more than 500 isolates from soil that had been heavily contaminated with various insecticides revealed the existence of a few microbes that are very active in degrading this compound to various metabolites.

Simazine: Degradation by Soil Microorganisms
Science, 1963A soil fungus, Aspergillus fumigatus Fres., is effective in the degradation of the herbicide 2-chloro-4,6-bis(ethylamino)- s -triazine (simazine). The degradation of both ring- and chain-labeled (C 14 ) simazine was observed in an unamended and an amended (sucrose ...

Soil and Groundwater Transport of Microorganisms
1991Releases of GEMs into the environment are expected to increase in the next few years, with the most dramatic increases resulting from the application of pest-control agents in agriculture and forestry. Of major significance in assessing the environmental risk impact of GEMs is an understanding of their survival and transport in soil and subsurface ...

The fate of methoxychlor in soils and transformation by soil microorganisms
Journal of Environmental Science and Health, Part B, 1984Methoxychlor was found to be sufficiently persistent in soil and its residues were present even 18 months after the soil treatment. Saprophytes, fungi and actinomyces were unaffected by varying concentrations of methoxychlor, azotobacter however was susceptable.

Decomposition of vanillin by soil microorganisms
Folia Microbiologica, 1971In chernozem soil, vanillin was decomposed via vanillic and protocatechuic acid before the aromatic ring opened. The rate curves of oxygen consumption for the oxidation of vanillin were seen to have more than one maximum. During incubation of the soil with vanillin, the number of bacteria increased, especially those capable of utilizing vanillin as the

Soils as Habitats for Microorganisms
2002It is more than a small step into the living sphere of microorganisms. They have special demands for their living space, like plants for their rooting space. The supply of heat, water, soil gases, organic matter and inorganic nutrients presents the general framework.

Enumeration of Soil Microorganisms
2005Objectives. Soil is a heterogeneousmatrix inwhichmicrobes are associated with organic and inorganic soil particles, forming aggregates. The goals of sample preparation for conventional enumeration techniques are to release the microbes from thematrix of a representative soil sample, then disperse them in a suitable diluent so that individual cells can ...
