Approximately 500 fatty acid profiles were prepared for 340 strains of plant-pathogenic and other bacteria currently or recently classified in the genus Pseudomonas Migula 1984. Strains representing some infraspecific taxa were included. The fatty acid profiles were stable and reproducible provided that cultural and chemical techniques were standardized. The 2and 3-hydroxy fatty acids were foun...

In vitro antimicrobial efficacy of leaves extracts of Murraya koenigii was performed by disc diffusion method against six Gram positive bacterial (Bacillus cereus, Bacillus megaterium, Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus subfava), nine Gram negative bacterial (Alcaligenes fecalis, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, P...

We studied the growth and capacities for pesticides removal of bacterial strains isolated from the Laguna Grande, an oligotrophic lake at the South of Spain (Archidona, Málaga). Strains were isolated from water samples amended with 10 and 50 microg/ml of nine pesticides: organochlorinated insecticides (aldrin and lindane), organophosphorous insecticides (dimetoate, methyl-parathion and methidat...

Strains of saccharolytic and nonsaccharolytic Pseudomonas species were examined by a new single-step gas chromatographic characterization procedure. Cells were digested in a methanolic solution of tetramethylammonium hydroxide pentahydrate, and the digestates were subjected to gas-liquid chromatographic analysis. The chromatograms were examined for similarities and differences in their overall ...

A new atisane-type diterpene, ent-16alpha-hydroxy-atisane-3,4-lactone (4) and three known diterpenes, ent-16alpha-hydroxy-atisane-3-one (1), ent-atisane-3beta,16alpha-diol (2), ent-3,4-seco-16alpha-hydroxyatis- 4(19)-en -3-oic acid (3) were isolated from the bark of the mangrove plant Excoecaria agallocha. Their structures and relative stereochemistry were elucidated by means of extensive NMR a...

In this study, species distribution and antimicrobial susceptibility of cultivated Pseudomonas spp. were studied in influent (INF), effluent (EFF), and marine outfall (MOut) of wastewater treatment plant (WWTP). The susceptibility was tested against 8 antimicrobial classes, active against Pseudomonas spp.: aminoglycosides, carbapenems, broad-spectrum cephalosporins from the 3rd and 4th generati...
