FT-IR spectra were recorded of Escherichia coli cell mass with the aim of obtaining spectral traits possibly useful in a rapid detection and characterisation of this indicator bacterium. A well differentiated spectrum was obtained from the cell mass

In the last decades, structural complexity and importance to natural environments of humic substances have been elucidated. Their persistence and/or susceptibility to biological decomposition, however, requires further research. Here we present a con

Humic acids (HAs) extracted from two soils under permanent meadow, and from a forest soil, were added as either a supplemental source of nutrients, or as the sole sources of carbon or nitrogen to cultures of microbial communities indigenous to the sa

Bacillus subtilis is an aerobic endospore forming bacterium widely spread in different environments. Because it represents a biological agent of some health relevance, its rapid detection and identification is highly desirable. By using FT-IR spectro

Since life is inevitably dependent on the assimilation and dissimilation of carbon, and since most of the organic carbon is bound in soil humic matter, the mineralisation and humification of plant carbon in soil should be monitored, so as to evaluate

A humic acid (HA) fraction of the soil organic matter (SOM) was extracted with alkali from soil samples originated in non-fertilized and fertilized (NPK + organic manure) plots of long-term (45 years) field experiments. The HA preparations served as

Humic acids (HAs) from a pseudogley soil with various metal contents were added as supplemental sources of nutrients, or as the sole sources of carbon or nitrogen, to aerobic cultures of complex microbial populations indigenous to the same individual

Aquatic humic substances (HS) from a bog lake water, a riverwater, and a groundwater were isolated after enrichment on XAD 8 columns and added to a Czapek-Dox nutrient broth which was used either in full strength or without glucose and/or NaNO3. The

Pseudomonads are ubiquitous bacterial inhabitants of soil and surface water with a variety of metabolic capacities. The isolation and identification of these bacteria is often required. A variety of methods have been employed to confirm the presence

Humic acids (HA) extracted with alkali from unfertilized and fertilized (NPK + organic manure) plots of long-term, i.e. 45 years, field experiments were added as a supplemental source of nutrients or as the sole sources of carbon and nitrogen to semi
