A new analytical procedure for the determination of alcohol ethoxylates (AE) in environmental samples such as influents, effluents and sludge from waste water treatment plants (WWTPs) was developed. Although some work had been previously published on

The characterization of alcohol ethoxylates (AE) to determine ethylene oxide (EO) adduct distribution has been studied in our laboratory for many years by using high-performance liquid chromatography-mass spectrometry (LC-MS). This paper describes th

Derivatization of a C12Φ-methyl ester sulfonic acid by using iodide-trifluoroacetic anhydride in dimethylformamide in a one-step reaction yielded derivatized sulfonic thiotrifluoroacetates. The latter have been analyzed by gas chromatography-mass sp

Aerobic biodegradation of the 2-butyl-octyl alcohol polyethoxylate (2Bu-C 8 AE) was investigated under laboratory standardized conditions (Organization for Economic Cooperation and Development 301E and 310B screening test protocols) to study the effe

Background Surfactants are widely used across the globe both in industrial and consumer products; their biodegradation characteristics are therefore of high importance. Upon entering a wastewater treatment plant (WWTP), the majority of surfactants ar

Screening for fungicidal activity carried out on culture broths of soil Streptomyces strains resulted in the isolation of two new macrolide polyene antibiotics, AB021-a and AB021-b, endowed with good protective activity against some plant diseases. T

AB023, a complex of new polyene antibiotics, was isolated from a soil Streptomyces strain. The two main components, pentaene antibiotics AB023a and AB023b, were separated and purified by preparative chromatographic methods and their structures were d

A simple method is discussed for the isolation of pseudobactin B, a new siderophore produced together with pseudobactin by plant growth promoting bacterium Pseudomonas PD 30. Pseudobactin B differs from the kown pseudobactin only by the nature of the

Screening for herbicidal compounds carried out on culture broths of Streptomyces strains isolated from soil resulted in the detection of potent phytotoxic activity. The active principles were isolated, and identified as the nucleoside antibiotics Bla

Collision-induced dissociation of protonated molecular ions in a mixture of macrotetralide antibiotics has been used to determine the sample make-up, as well as the structures of the components in the mixture. Upon 3 keV gaseous collisional activatio
