Extended-spectrum β-lactamases from the class D, metallo-β-lactamases from the class B with four major families (IMP, VIM, SPM, and GIM families), OXA-type enzymes, class A carbapenemases of the KPC family also have been found within P. aeruginosa. Also drench the soil near the root zone of the plant; The first spray can be done between 30 to 45 days after sowing or planting. Porin OprD takes part in uptake of basic amino acids, small peptides and carbapenems (such as imipenem and meropenem) [69, 70]. Two siderotyping methods can be improved by mass spectrometric determination of the molecular mass of pyoverdines [13, 55, 56]. Besides porins, P. aeruginosa has numerous and highly efficient efflux mechanisms to resist to antibiotics. Another recently introduced method for taxonomic investigations of bacteria is multilocus sequence typing/analysis (MLST/MLSA). Genus Pseudomonas represents a diverse group of bacteria including a large number of species. They make PHAs suitable for use in the packaging, medicine, pharmacy, agriculture and food industries [58]. Brief introduction to this section that descibes Open Access especially from an IntechOpen perspective, Want to get in touch? Representatives of the genus can utilize common monosaccharides (glucose, fructose, galactose, l-arabinose), but growth of some species (P. stutzeri, P. mendocina, P. syringae) may be slow. They stimulate growth by several mechanisms. Elevated concentrations of dyes and oxygen decelerate color removal [162-167]. It’s based on principles of collaboration, unobstructed discovery, and, most importantly, scientific progression. Vast potential of pseudomonads as biocontrol agents was demonstrated. production strategies by Pseudomonas Aeruginosa, its agriculture and food industrial applications are also discussed. Therefore, it was shown that resistance to β-lactam antibiotics does not seem to involve loss or modification of OprF [68]. They stimulate growth by several mechanisms. © 2015 The Author(s). TWBP was mixed with soil at different concentrations (2g TWBP + 10g soil, 4g TWBP + 10 g soil, 6g TWBP + 10g soil, 8g TWBP + 10g soil and 10g TWBP + 10g soil) and inoculated in minimal salt medium. Some P. aeruginosa strains, like PA14, also cause disease in a variety of nonvertebrate hosts, including plants, Caenorhabditis elegans, and the greater wax moth, Galleria mellonella [60]. Pseudomonas spp. The data available indicates the 2-3% of pesticide is actually used and rest persists in soil and water causing environmental pollution leading toxicity to the biodata. Pili are essential for the normal development of P. aeruginosa biofilms, and they also function as receptors for bacteriophage binding [5-7]. The ben and cat genes are located together in the genomes of P. fluorescens, P. aeruginosa, P. stutzeri, and P. entomophila. are degraded via the intermediate protocatechuate. To date our community has made over 100 million downloads. Most hexoses and related compounds are also degraded by the Entner-Doudoroff pathway and various peripheral pathways [2, 14, 17]. Keratinolytic bacteria were better enzyme producers than the chitinolytic ones, and oil removal in the presence of chicken-feathers was 3.8 times higher than with shrimp wastes, and almost twice, in comparison with oil-only added cultures [123]. Increasing AmpC production provides for resistance to all β-lactams, except the carbapenems.

There are many methods allowing to identify and classify the Pseudomonas genus, but gene sequencing procedures proved the most advanced and sophisticated. Strains of different species were subjected to many phenotypic tests, the most important of which was the nutritional screening [21]. Pseudomonas may be used as biocontrol agents that reduce disease severity and promote plant growth. Apart from their uses based on their special properties, rhamnolipids yields produced by Pseudomonas … However, a small number of bacteria can survive under simultaneous action of both treatments [99]. Another possible application of Pseudomonas is bioremediation. Someone with the name of Another possible tool for Pseudomonas taxonomy is fluorescence spectroscopy. The best studied organism among pseudomonads is P. aeruginosa. *Address all correspondence to: galina_novik@mbio.bas-net.by, Microbiology in Agriculture and Human Health. Enterobacterial repetitive intergenic consensus PCR (ERIC-PCR) is also an effective method for identification of Pseudomonas genotypes. The bacteria can produce some … Other pigments produced by species of Pseudomonas include pyocyanin (P. aeruginosa, blue color), pyorubin (P. aeruginosa, red color), chlororaphin (P. chlororaphis, green color), pyomelanin (P. aeruginosa, brown/black color). Research revealed that 66 genes changed expression level in response to both stressors [140]. Only rRNA group I that included the type species P. aeruginosa, all the fluorescent (P. fluorescens, P. putida, P. syringae), and some non-fluorescent species (P. stutzeri, P. alcaligenes, P. pseudoalcaligenes, P. mendocina) reserved the name Pseudomonas. Loop 1, loop 5, loop 6, loop 7, and loop 8 are not involved in the passage of imipenem, but either the deletion or amino acid substitutions of loop 5, loop 7, and loop 8 resulted in increased susceptibility to β-lactams, quinolones, chloramphenicol, carbapenems and tetracycline [71-76]. The strain degraded nicotine completely when the concentration of reducing sugar in TWE (tobacco waste extract) was lower than 8 g/L. analysis of emission spectra of three intrinsic fluorophores (NADH, tryptophan, and the complex of aromatic amino acids and nucleic acid) allowed to clearly discriminate Pseudomonas at genus level from Burkholderia, Xanthomonas and Stenotrophomonas. Imipenam was found to bind to sites in loop 2 to block channel function. Pseudomonas species thrive under moist conditions in soil (particularly in association with plants), in sewage sediments and the aquatic environments.
