Microbial Indicators for Environmental Pollution

2023
Environmental pollution has become a serious issue of concern across the world. Intensive agriculture, industrialization, and consumerism have resulted in the degradation of environmental quality. The presence of pollutants like fertilizers, pesticides, persistent organic pollutants (PoPs), polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls ...

Microbial indices of soil fertility

Journal of Applied Microbiology, 2005
To find the new microbial parameters explaining the soil fertility from the microbial community viewpoint.Fatty acid methyl ester (FAME) analysis and terminal-restriction fragment length polymorphism (T-RFLP) analysis were carried out using 16 differently treated plots from the same field that had been kept under different fertilizer management systems

Culturability as an Indicator of Succession in Microbial Communities

Microbial Ecology, 2001
Successional theory predicts that opportunistic species with high investment of energy in reproduction and wide niche width will be replaced by equilibrium species with relatively higher investment of energy in maintenance and narrower niche width as communities develop.

Microbial Indicators of Nutrient Enrichment

Soil Science Society of America Journal, 2006
Microbial communities are in close contact with the wetland soil microenvironment and can therefore function effectively as monitors of soil pollution. The objective of this study was to determine changes in the functional responses of microbial communities as a result of an external input of nutrients, while controlling for ...

Toward the development of microbial indicators for wetland assessment

Water Research, 2013
Wetland assessment tools are being developed and employed in wetland monitoring and conservation based on physical, chemical and biological characterization. In wetland biological assessment, various ecological functions have been described by biological traits of an entire species pool that adapts to different types of wetland environments.

Microbial indicator groups in acidic mining lakes

Environmental Microbiology, 2004
Summary The salt composition of 14 acidic lakes was analysed, and their microbial communities were compared by their 16S rDNA‐based single‐strand conformation polymorphism (SSCP) fingerprints. The lakes were grouped into three chemically distinct types, and operational taxonomic units (OTUs) were identified in the

Chapter 8 Microbial indicators

2003
Abstract Micro-organisms are present in high amounts in all kinds of environments and play key roles in important ecosystem functions such as decomposition and nutrient cycling. Their small size and high surface to volume ratio causes a high affinity for very low concentrations of substances .

Microbial Indicators of Eutrophication in Everglades Wetlands

Soil Science Society of America Journal, 2009
Nutrient loading has been implicated as a major cause of ecological changes in Everglades wetlands. The main objective of this study was to assess changes in microbial indicators in response to nutrient loading across the Everglades landscape. Soil chemical, physical, and microbial properties were measured for nutrient‐impacted and oligotrophic sites ...
