The multidrug resistance plasmid pBWH301 was shown to contain a sull- associated integron with five inserted gene cassettes, aacA7-catB3-aadB- oxa2-orfD, all of which can be mobilized by the integron-encoded DNA integrase. ...

The new attached growth sponge tray bioreactor (STB) was evaluated at different operating conditions for removing organics and nutrients from primary treated sewage effluent. This STB was also assessed when using as a ...

A new trimethoprim resistance determinant, designated dhfrX, was identified in the In7 integron of pDGO100. The sequence of the dhfrX dihydrofolate reductase is up to 28% identical to the sequences of several known ...

Nitric oxide ( NO) is a pleiotropic signalling molecule that binds to cytochrome c oxidase (complex IV) reversibly and in competition with oxygen(1-3). This action of NO has both physiological and pathophysiological ...

A highly selective liquid membrane nitrite microsensor based on the hydrophobic ion-carrier aquocyanocobalt(III)-hepta(2-phenylethyl)-cobrynate is described. The sensor has a tip diameter of 10 to 15 (mu)m. The response ...

Accelerating rates of species extinction and invasion have sparked recent interest in how changes in plant community composition can be propagated through food webs. Research in this area has, however, been largely restricted ...

The lack of information about mobile DNA in deep-sea hydrothermal vents limits our understanding of the phylogenetic diversity of the mobile genome of bacteria in these environments. We used culture-independent techniques ...

The nucleotide sequence of a 1.9 Kb HindIII fragment of DNA derived from the AROM locus of A.nidulans and encoding the biosynthetic dehydroquinase activity has been determined. The sequences encoding the biosynthetic and ...
