Five bacterial strains capable of using sulphoquinovose (6-deoxy-6-sulpho-D-glucopyranose) as a sole source of carbon have been isolated and partially characterized.

Plastic materials are playing an increasingly important role in our everyday lives. As a consequence, they are more frequently exposed to the environment; and the impact they or their additives might have on the latter becomes an important concern. Plasticizers are the most common additives found in plastics. They are used to improve on their physical properties (e.g. flexibility, workability)....

An unidentified Pseudomonas capable of growth on ferrichromes as sole sources of carbon and nitrogen was isolated by enrichment culture on ferrichrome A. The spectral shifts observed for the culture supernatant fluids and the degradation products which accumulated in the culture media during growth on these compounds indicated that initially the cyclic peptide rings are broken to yield simpler ...

MANAGEMENT of post-harvest residues, produced during the green-cane harvesting of sugarcane in Louisiana, has become an increasingly important issue for producers, particularly in areas where burning of the residues is banned or restricted. If the residues, which range from 4–8 tonnes per hectare, are not removed prior to the emergence of the subsequent ratoon crop in the spring, yields may be ...

Synthetic compounds, particularly highly chlorinated aromatics, comprise the bulk of the environmental pollutants that somehow must be removed from the environment. Microbial degradation of such compounds is usually very slow, making them highly persistent in nature. Some synthetic compounds, with a lower degree of chlorination are, however, biodegradable; biochemical, genetic, and molecular st...

The organophosphate pesticide, Ethion, remains a major environmental contaminant in rural Australia and poses a significant threat to environmental and public health. The aerobic degradation of Ethion by mesophilic bacteria isolated from contaminated soils surrounding disused cattle dip sites was investigated. Two isolates, identified as Pseudomonas and Azospirillum species, were capable of bio...

Chlordecone (Kepone®) is a synthetic organochlorine insecticide (C10Cl10O) used worldwide mostly during the 1970 and 1980s. Its intensive application in the French West Indies to control the banana black weevil Cosmopolites sordidus led to a massive environmental pollution. Persistence of chlordecone in soils and water for numerous decades even centuries causes global public health and socio-ec...

Anaerobic digestion of biomacromolecules in various microbial ecosystems is influenced by the variations in types, qualities, and quantities of chemical components. Nuclear magnetic resonance (NMR) spectroscopy is a powerful tool for characterizing the degradation of solids to gases in anaerobic digestion processes. Here we describe a characterization strategy using NMR spectroscopy for targeti...

This study presents results of research on a number of microorganisms in soil of the Chełmżyńskie lake watershed and their role in the decomposition of chitin. The authors also examined the level of respiration activity of soil in the presence of shrimp waste. Results demonstrate that the number of microorganisms in soil were variable. During the entire research period, the analyzed groups of m...
