The soil-borne fungal pathogen Verticillium longisporum is able to penetrate the root of a number of plant species and spread systemically via the xylem. Fumigation of Verticillium contaminated soil with Brassica green manure is used as an environmentally friendly method for crop protection. Here we present a study focused on the potential role of glucosinolates and their breakdown products of ...

Abiotic degradative pathways are often overlooked when evaluating natural attenuation at chlorinated solvent sites. Yet, at many sites, significant degradation of parent compounds such as 1,1,1-TCA, PCE and TCE is observed without the corresponding accumulation of daughter products, a sure indication of abiotic reactions. The problems in integrating abiotic processes into MNA are how to prove t...

The present study aims at phytoremediation of Lemna gibba L. in aqueous solutions with different concentrations of TC and Degradation Products (DPs). It also tries to determine whether there are differences in TC, ETC, EATC, and ATC levels, accumulated by Lemna gibba L. Exposure concentrations of 50, 100, and 300 ppb have been selected for TC and DPs, showing that the highest TC50, TC100, and T...

The enzymatic degradation of amino acids in cheese is believed to generate aroma compounds and therefore to be essential for flavor development. Cystathionine beta-lyase (CBL) can convert cystathionine to homocysteine but is also able to catalyze an alpha, gamma elimination. With methionine as a substrate, it produces volatile sulfur compounds which are important for flavor formation in Gouda c...

Aldehydes as secondary lipid oxidation products are highly specific to the oxidative degradation of particular polyunsaturated fatty acids present in foods. Gas chromatographic analysis of those volatile compounds has been widely used for monitoring of the deterioration of food products. Developed static headspace gas chromatography method using flame ionization detector (SHS GC FID) was applie...

A DC positive streamer discharge has been characterized by measuring current/voltage relation, ozone and NOx production. Due to its relevance in the field of indoor air treatment, the effect of humidity was examined. The goal of this research is to use the corona discharge reactor for the abatement of low levels of toluene from indoor air. Experiments proved that toluene (concentrationin = 0.5 ...

Thermal treatment is a suitable method for improving the quality of wood types like spruce, beech, or poplar, and thus to open up new fields of application that used to be limited to tropical woods or woods treated with timber preservatives. These thermally treated woods are characterized by a typical odor caused by degradation products of miscellaneous wood components. The characterization and...
