Effect of organic matter enrichment on the fungal community in limestone cave sediments
Genetics and Molecular Research, 2016 Caves are considered major touristic attractions. The management plans of many such caves include limiting the number of visitors; however, the human impact on microbial communities within caves is rarely considered. Therefore, the aim of this study was to evaluate the impact of human-transferred organic matter on the fungal microcosms growing on cave ...

Seasonal Response of Stream Biofilm Communities to Dissolved Organic Matter and Nutrient Enrichments [PDF]
Applied and Environmental Microbiology, 2005 ABSTRACT Dissolved organic matter (DOM) and inorganic nutrients may affect microbial communities in streams, but little is known about the impact of these factors on specific taxa within bacterial assemblages in biofilms. In this study, nutrient diffusing artificial substrates were used to examine bacterial responses to DOM (i.e.,

Fractions of particulate organic matter in soils depending upon farmyard manure and mineral fertilization [PDF]
, 2002 In a long-term fertilization trial particulate organic matter (POM) was investigated after 20 years of farmyard manure vs. mineral fertilization at different levels with the method of Meijboom et al. (1995).

Enrichment of Lignin-Derived Carbon in Mineral-Associated Soil Organic Matter
Environmental Science & Technology, 2019 A modern paradigm of soil organic matter proposes that persistent carbon (C) derives primarily from microbial residues interacting with minerals, challenging older ideas that lignin moieties contribute to soil C because of inherent recalcitrance.

Impact of mercury atmospheric deposition on soils and streams in a mountainous catchment (Vosges, France) polluted by chlor-alkali industrial activity: The important trapping role of the organic matter [PDF]
, 2006 Total atmospheric Hg contamination in a French mountainous catchment upstream from a chlor-alkali industrial site was assessed using Hg concentrations in the deepest soil horizon, in the stream bottom sediments, in river waters and in bryophytes.

Plant and Soil, 2007 Maintenance of soil organic matter (SOM) at levels that sustain optimal supply of soil nutrients and enhance efficiency of externally added fertilizers is a major challenge for smallholder farming systems of southern Africa. A study was conducted to quantify the interactive effects of organic resource quality and management on SOM formation and ...

Interactions between metals and soil organic matter in various particle size fractions of soil contaminated with waste water [PDF]
, 2009 Only scarce field studies concern the consequences of natural soil organic matter (SOM) and metal interactions on SOM dynamics in soils. We investigated the interactions of four metals (Pb, Zn, Cu and Cd) with the SOM associated to five different size ...
