In the River Saar, the distribution of methane-oxidizing bacteria and their metabolic activity were determined in vertical and longitudinal profiles. At the sediment surface about two orders of magnitude more methane oxidizers were detected than in t

Summary: Ureases of the cyanobacteria Leptolyngbya boryana (Plectonema boryanum) PCC 73110 and AnabaenalNostoc PCC 7120 were purified more than 1500-fold to homogeneity by heat treatment and liquid chromatography, reaching specific activities of up t

The transport of ammonium and methylammonium was studied in a strain of Ochrobactrum anthropi, a microorganism isolated from garden soil and able to degrade methyleneureas which are used as slow-release nitrogen fertilizer. The activity of both trans

The mechanism of ammonium uptake was studied in Pseudomonas aeruginosa, measuring the uptake (transport and metabolism) of [14C]methylammonium (MA). This ammonium analogue was not utilized for growth, but unmetabolized MA was accumulated to intracell

A fragment of chromosomal DNA from proteus vulgaris encoding urease was cloned and expressed in Escherichia coli. A 3 kbp region was sequenced and revealed three open reading frames with homology to jack bean (Canavalia ensiformis) urease. The smalle

Long term storage techniques for the preservation of Helicobacter pylori were developed. The cells survived at -75 degrees C in the presence of glycerol and at +4 degrees C after freeze-drying. Both techniques are suitable for routine use.

Nitrification was studied, using samples of asbestos concrete plates and water, both taken from a cooling tower, in which ammonia-containing water had been circulated for several years. Almost the entire nitrifying activity and the majority of autotr
