A protein (NosA) in the outer membrane of Pseudomonas stutzeri that is required for copper to be inserted into N2O reductase has been extracted and purified to homogeneity. The purified protein could form channels in black lipid bilayers. Like N2O reductase, NosA contained copper and was only made anaerobically. In contrast to N2O reductase, its synthesis was repressed by exogenous copper (but ...

Pseudomonas syringae pv. actinidifoliorum causes necrotic spots on the leaves of Actinidia deliciosa and Actinidia chinensis. P. syringae pv. actinidifoliorum has been detected in New Zealand, Australia, France and Spain. Four lineages were previously identified within the P. syringae pv. actinidifoliorum species group. Here, we report the draft genome sequences of five strains of P. syringae p...

Since 2008, Pseudomonas syringae pv. actinidiae, the causal agent of bacterial canker of kiwifruit has become the main pathogen of yellow and green fleshed kiwifruit. All major kiwifruit producing countries in the world have been affected by this bacterial pathogen, leading to substantial economic losses. This review presents the current knowledge on various aspects about the origin, epidemiolo...

The relationship of pyoverdins produced by 41 pathovars of Pseudomonas syringae and by phytopathogenic Pseudomonas species was investigated. A high-performance liquid chromatography method for analyzing the culture medium proved to be superior to isoelectric focusing for detecting pyoverdin production, for differentiating slightly different pyoverdins, and for differentiating atypical from typi...

In most environments many microorganisms live in close vicinity and can interact in various ways. Recent studies suggest that bacteria are able to sense and respond to the presence of neighbouring bacteria in the environment and alter their response accordingly. This ability might be an important strategy in complex habitats such as soils, with great implications for shaping the microbial commu...

The taxonomic position of Pseudomonas sp. B13(T), isolated as a 3-chlorobenzoate-degrading organism and used for several groundbreaking studies on the enzymology and genetics of the degradative pathway for haloaromatic compounds, was studied in detail. The previously performed physiological studies, the detection of ubiquinone Q-9, the polyamine pattern with putrescine and spermidine as major p...

This article sheds light upon an important but neglected context in which Thomas Barlow (1608/9–1691) and his contemporaries discussed the readmission of Jews 1655–56. Previous studies have shown how English perception evolved, few noticed that saw controversy as part a larger debate on limit civil magistrate’s power religious toleration. By recovering specific political 1655–56, idea natural l...

In this paper, a robust stabilization problem for a class of uncertain systems is studied using sliding mode techniques. Matched and mismatched uncertainties are both considered. By employing the sliding surface proposed by Edwards and Spurgeon in [Int J Control 1995; 62(5): 1129–1144], the stability of the sliding mode is shown first. Then, an asymptotic observer is established to estimate the...
