Factors governing the turnover of organic matter (OM) added to soils, including substrate quality, climate, environment and biology, are well known, but their relative importance has been difficult to ascertain due to the interconnected nature of the soil system. This has made their inclusion in mechanistic models of OM turnover or nutrient cycling difficult despite the potential power of these...

The improved methods to analyze DNA or RNA from soil enable us to study microbial diversity and functions in soil which have never been revealed by conventional culture methods. Using one of such metagenomic approaches, polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE), we succeeded in monitoring the change of microbial diversity in the soil treated with a chemicals o...

BACKGROUND AND AIMS The objective of this work was to determine the influence of the soil substrate on the characteristics and properties of a specific type of honey. As such, we analysed the features of a typical single-flower honey, thyme honey, produced in a specific Mediterranean region. Thymus is a genus of aromatic perennial plants that are native to Europe, North Africa and Asia. METHO...

As indicated by its title, the book ‘Chemistry for Environmental Scientists’ aims at covering a very broad field of knowledge. After a short and general introduction, it is divided in four chapters, namely ‘Chemistry under environmental conditions’, ‘Fundamentals of physical chemistry’, ‘Chemistry of the elements and its [sic] compounds in the environment’ and ‘Chemical processes in the environ...

grain quality currently represents a major problem in high yielding rice production in iran and many other rice producing areas of the world. quality assessment of rice involves the function of sensory tests and physicochemical determinations based on the chemical composition, cooking quality, gelatinization temperature and physical properties of cooked rice. these research genetic materials we...

The similarities and differences in the structures of the nifH gene pools of six different soils (Montrond, LCSA-p, Vernon, Dombes, LCSA-c, and Thysse Kaymor) and five soil fractions extracted from LCSA-c were studied. Bacterial DNA was directly extracted from the soils, and a region of the nifH gene was amplified by PCR and analyzed by restriction. Soils were selected on the basis of differenc...
