Introduction to Fluorescent Pseudomonads

The contribution of phenazines to the formation of biofilms suggests that Burkholderia, like fluorescent pseudomonads, may benefit from the unique redox-cycling properties of these versatile secondary metabolites.

The oxidative bacteria were phenotypically grouped within the fluorescent pseudomonads.

In all cases, the rpoD amplicon approach identified more species than were found by cultivation, including hard-to-culture nonfluorescent pseudomonads, as well as more than were found by 16S rRNA V3-V4 amplicon sequencing.

Densities of culturable bacteria, fluorescent pseudomonads and nematodes, hydrolysis activity and soil DNA content declined by over 50% immediately after both microwave treatments (T0), excluding the total fungal 18S rRNA (−13 or −17%) and bacterial 16S rRNA copies (non-significant).

In all cases, the rpoD-amplicon approach identified more species than found by cultivation, including hard-to-culture non-fluorescent pseudomonads, as well as more than found by 16S rRNA V3V4 amplicon sequencing.

Microbial biomass, the density of culturable heterotrophic bacteria and fluorescent Pseudomonads as well as fluorescein di‐acetate hydrolysis decreased significantly by 2.

The compound and its derivatives have been isolated from rhizospheric fluorescent or non-fluorescent pseudomonads, Serratia and Burkholderia.

Populations of general bacteria, general fungi, bacilli, and florescent pseudomonads were unaffected by field solarization, but fluorescent pseudomonads were reduced following greenhouse solarization.

In the present investigation, 35 native isolates of fluorescent pseudomonads from wilt-affected pomegranate orchards were isolated, purified, and characterized.

solanacearum density after corn coincided with the high ratio of fluorescent pseudomonads, endospores, and actinomycetes, being most clear in the poor soils (Wardan) and less clear under iron excess at Ganoub El-Tahrir as well as the clay soils.

1 strain within Pseudomonas gessardii subgroup of fluorescent pseudomonads, where it formed a distinct clade with other Pseudomonas strains, most of which also contained a complete thioquinolobactin gene cluster.

In general, CLP types were linked to specific taxonomic groups within the fluorescent pseudomonads.

This provides opportunities to develop inhibitors that target the allosteric site, which seems to be confined to fluorescent pseudomonads, and not the tyrosinase active site.

All strains, belonging to the fluorescent pseudomonads, exhibited plant growth-promoting properties, including phosphorus solubilization and production of siderophore, indole acetic acid, and 1-aminocyclopropane-1-carboxylic acid deaminase.
