An Insight Into Beneficial Pseudomonas bacteria

Abstract

Pseudomonas is a widespread bacterial genus embracing a vast number of species. Various genosystematic methods are used to identify Pseudomonas and differentiate these bacteria from species of the same genus and species of other genera. Ability to degrade and produce a whole spectrum of compounds makes these species perspective in industrial applications. It also makes possible to use various media, including wastes, for cultivation of Pseudomonas. Pseudomonads may be applied in bioremediation, production of polymers and low-molecular-weight compounds, biocontrol. Recent studies open up new frontiers for further use of Pseudomonas in various areas.

Isolation, purification and characterization of a novel solvent stable lipase from Pseudomonas reinekei

“…Pseudomonas sp. is one of the most studied bacterial species [51]; and lipases from these have been extensively explored. In this study, a novel lipase from P. reinekei was discovered and when fully characterised, displayed high stability in a variety of industrially relevant organic solvents.…”

Pseudomonas PS01 Isolated from Maize Rhizosphere Alters Root System Architecture and Promotes Plant Growth

“…Prior to application of microorganisms for agronomic purposes as a bio-inoculant, scenario safety testing and risk assessment evaluation was required. For instance, P. aeruginosa is an opportunistic human pathogen, whereas other species of Pseudomonas are non-pathogenic when used in agriculture [22,57]. In this context, potential strains must be taxonomically characterized at species and strain level using several approaches including whole genome sequencing and classified into the risk-group/ biosafety level (BSL) of the organism [57].…”

“…Regarding the potential health risk of PGPR to human, efforts in characterization of the isolates at the species level should be employed before proceeding with formulation development or pilot and largescale field level applications. Currently, agricultural microbiologists are mainly focused on the beneficial traits of the isolates while ignoring the possible existence of opportunistic human or animal pathogenicity [22,23]. Therefore, it is highly desirable to use phylogenomic data for exact taxonomy classification.…”

Classification and Taxonomy of Vegetable Macergens

“…Based on their ability to degrade pectin and macerate the plant parenchymatous tissues they are referred to as P. marginalis . Recently, based on 16S rRNA analysis Anzai et al (2000) came up with 57 strains of Pseudomonas sensu stricto with seven subclusters: P. syringae group, P. chlororaphis group, P. fluorescens group, P. putida group, P. stutzeri group, P. aeruginosa group, and P. pertucinogena group ( Novik et al, 2015 ). Also, in the same genus Pseudomonas , some species have been found to be misclassified for instance P. aureofaciens and P. aurantiaca , which were reclassified into P. chlororaphis ( Peix et al, 2007 ).…”

“…Siderotyping an interesting taxonomic tool was used in characterizing fluorescent and then to non-fluorescent based on the isoelectrophoretic. Characterization of the major siderophores and pyoverdines and determination of strains pyoverdine mediated iron uptake specificity led to characterization of several Pseudomonas strains at species level, through species-specific pyoverdines ( Novik et al, 2015 ). Mass spectrometry for the determination of molecular mass of pyoverdines has helped recently to improve siderotyping resolution power and accuracy ( Meyer et al, 2008 ).…”
