Samples were taken from sediment of the River Spittelwasser (district Bitterfeld, Germany), which is highly polluted with PCDD/Fs and other chloroorganic compounds. The sediment cores were separated into 10-20 cm thick layers, spiked with 50 microM of 1,2,3,4-tetrachlorodibenzo-p-dioxin and incubated for 8 months under anaerobic conditions in the presence(More)
The bacterial strain mA3 capable of utilizing 3-aminophenol as the sole source of carbon, energy and nitrogen for growth was isolated from an enrichment culture and identified as an Arthrobacter species. Utilization of 0.68 mg/ml 3-aminophenol by batch cultures of this organism was characterized by a specific growth rate (mu) of 0.18 h-1 and a yield(More)
The C2 is a high{end immersive virtual reality environment that allows 3{dimensional projections of higher dimensional objects. It is our intention to make use of the C2 to explore new statistical graphics applications based on single, multiple, or sequences of 3{dimensional projections. We also plan to explore navigation tools for steering through(More)
After 10 years of research in Virtual Environments, interactive real time Virtual Reality systems are now available that even support highly immersive, interactive presentations for large audiences. Following the single-user head mounted technology of the early days, multi channel stereo projection systems are now applied in nearly all application domains,(More)
A Gram- negative rod-shaped bacterium 28/1 isolated by enrichment cultures is able to hydrolyze the amide bond of some phenylurea herbicides and acid anilide herbicides by an inducible amidase. 7.5% of 0.3 mumol.ml-1 linuron (3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea) are hydrolyzed after 16 hours. 1,1-Dimethylphenylureas are not degraded. Acid anilides(More)
