New species of Pseudomonas belonged to Fluorescent Group

Identification of fluorescent Pseudomonas species.

Fluorescent pseudomonads may be identified through examination of the fluorescence "profiles" of diffusible pigments released into the growth medium. The profiles are obtained in the form of an emission-excitation matrix, the elements of which correspond to fluorescence intensity as a function of multiple exciting and emitting wavelengths. Use of a rapid scanning fluorometer to acquire these da...

Pseudomonas fluorescent and its ability to promote root formation of olive microshoots

Root formation and root architecture of olive microshoots, inoculated or not with Pseudomonas fluorescent P19 or P21, were evaluated by measuring of length and the numbers of adventitious and lateral roots. Three-four nodal in vitro shoots were treated with different population densities (0, 105, 108 CFUml-1) of rhizobacteria. The density of 108 CFUmgl-1 induced almost two times increase in num...

New group D streptococcal species.

BACKGROUND & OBJECTIVES The heterogeneity of group D streptococci led to the identification of various biotypes of Streptococcus equinus and Streptococcus bovis and to the description of new species. The objective of the present study was to improve the phenotypic delineation between species and to clarify their respective phylogenetic position. METHODS Physiological and genomic analyses were...

protease and urease production during utilization of diesel by fluorescent pseudomonas species isolated from local soil

background and objectives: bacteria, most prevalently the pseudomonas species possess high capacity to utilize and de- grade petroleum hydrocarbons and are classified as the hydrocarbonoclastic microorganisms. many species of the genus pseudomonas are notorious for their aerobic degradation capacity, extracellular enzyme production and are metabolically versatile organisms capable of utilizing ...
