The production of cyclic lipopeptides (CLPs) with antifungal and biosurfactant properties by Pseudomonas fluorescens strains was investigated in bulk soil and in the sugar beet rhizosphere. Purified CLPs (viscosinamide, tensin, and amphisin) were fir

Pseudomonas sp. DSS73 was isolated from the rhizoplane of sugar beet seedlings. This strain exhibits antagonism towards the root-pathogenic microfungi Pythium ultimum and Rhizoctonia solani. Production of the cyclic lipopeptide amphisin in combinatio

Seasonal dynamics of in situ gross nitrogen (N) mineralization rates were measured using the 15N-NH4+ isotope dilution method in a Danish soil subjected to four different agricultural practices (set aside, barley, winter wheat and clover). Results we

Formamide hydrolase activity in a barley field soil was described by a two-component, rather than a one-component model of Michaelis–Menten kinetics. The two-component model had both a high-affinity ( K m values of 0.5–1.0 mM) and a low-affinity

Nitrification, denitrification and nitrogen liberation were studied while liquid cattle manure and duck litter decomposed in aerobic soil contained in a diffusion chamber. The high NH4+ outflux from the liquid manure initially saturated the indigenou

The importance of microbial urea turnover in N cycling was investigated in three agricultural soils by comparison of gross N mineralization determined by the 15N-NH+4 dilution technique and urea turnover determined by a new 14C-urea tracer technique.

Investigations of subsoil denitrification have been hampered by the difficulty in adapting traditional methods for measuring denitrification in surface soils to subsoils. In this study, we present, and test, a combination probe constructed to detect
