Thin-layer chromatography was used to detect the presence of the arginine dihydrolase system in nonfermentative gram-negative bacteria. The test was positive for the fluorescent pseudomonads as well as Pseudomonas maltophilia, whereas other Pseudomonas sp., Mima, and Herellea were negative. This procedure can be completed in a few hours and may be useful in the clinical laboratory.

A total of 47 psychrotrophic pseudomonads isolated from raw milk came from Newfoundland (19 isolates), British Columbia (6 isolates), Ontario (19 isolates), and Cork, Ireland (3 isolates). The susceptibility of these was tested against 30 bacteriophages isolated from cold-storage beef. Distinct lysotypes were observed with isolates representing different geographic regions. Phages as agents in ...

Fluorescent pseudomonads were a major component [log (10) 4.2-6.1 colony-forming units mL-1] of the culturable heterotrophic gram-negative bacterioplankton observed in three Mississippi Delta oxbow lakes in this study. Pure cultures of fluorescent pseudomonads were isolated from three Mississippi Delta oxbow lakes (18 per lake), using selective media S-1. Classical physiological tests and Biolo...

In this study presence of various kinds of microorganisms in kitchen sponges were studied. Additionally effects of regular dish washing liquid on Escherichia coli ATCC 8739 and Salmonella typhimurium ATCC 13311 were investigated under laboratory conditions in kitchen sponges with or without food residue. The sponges involved in daily use in households were samples were analysed for the presence...

We pursue the definition of a KZ-doctrine in terms of a fully faithful adjoint string Dd m dD. We give the definition in any Gray-category. The concept of algebra is given as an adjunction with invertible counit. We show that these doctrines are instances of more general pseudomonads. The algebras for a pseudomonad are defined in more familiar terms and shown to be the same as the ones defined ...

Methods In the present study, marine fluorescent pseudomonads were screened against various human pathogenic bacteria and plant fungal pathogens. An autolyzed cell free culture filtrate of selected isolate was used for the synthesis of silver nano particles and characterized using UV, FTIR, XRD and AFM analysis. The antimicrobial efficiency along with larvicidal activity of the synthesized nano...

The enzymatic conversions necessary for the catabolism of branched-chain amino acids have been reported to occur in a wide variety of bacteria. However, most studies have been done using several species of Pseudomonas. Pseudomonads are richly endowed with extraordinary nutritional versatility, which enables them to catabolize a diverse array of organic compounds (64), including the branchedchai...
