Abstract:
This study aimed to select and identify elite strains of plant growth-promoting rhizobacteria (PGPR) among phosphate-solubilizing bacteria (PSB) conserved at the Ethiopian Biodiversity Institute. In-vitro screening for plant growth-promoting traits and abiotic stress tolerance identified 12 promising PGPR isolates. These strains exhibited phosphate solubilization (index 1.8–3.2), auxin production, nitrogen fixation, and ammonia production. All isolates showed drought tolerance, and some exhibited salt tolerance (up to 10% NaCl). 16S rDNA sequencing identified Pseudomonas frederiksbergensis, Ps

Abstract:
Fluorescent Pseudomonas spp. isolated from fruiting bodies (FB) of Cantharellus cibarius were characterized physiologically and genetically and were compared with fluorescent Pseudomonas from forest soil and with sequences from the GenBank database. Pseudomonas spp. from FB differed physiologically from isolates from soil lacking FB and had some similarities with the strains obtained from soil underneath the FB. Analyses of the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) patterns and partial sequencing analysis of the 16S-rDNA region indicated that the b

Abstract:
The pine wood nematode (PWN) Bursaphelenchus xylophilus is the pathogen that causes pine wilt disease (PWD), a devastating forest disease. PWN-associated bacteria may play a role in PWD. However, little is known about the endo-bacteria in PWN. We analyzed the diversity of endo-bacteria in nine isolates of PWNs from Pinus massoniana Lamb. in nine epidemic areas from three Chinese provinces by high-throughput sequencing of 16S rDNA and isolated and identified culturable endo-bacteria through construction of a 16S rDNA phylogenetic tree and Biolog microbial identification.

Abstract:
A 2,4-Dinitrotoluene degrading bacterium was isolated from sludge contaminated by DNT and identified as a member of Pseudomonas fluorescens sp. based on 16S rDNA sequence. Under growth substrates limited conditions, the strain was enriched with 2,4-DNT as its sole source of carbon and energy in the groundwater environment. Results indicate the isolate grew optimally at 12(±4)°C and initial pH 7.5 in the mineral salts medium supplemented 2,4-DNT with 40mg/L, thus showing potential for the remediation of 2,4-DNT contaminated groundwater.

Abstract:
ABSTRACT Fluorescent Pseudomonas strains were isolated from 38 undisturbed pristine soil samples from 10 sites on four continents. A total of 248 isolates were confirmed as Pseudomonas sensu stricto by fluorescent pigment production and group-specific 16S ribosomal DNA (rDNA) primers. These isolates were analyzed by three molecular typing methods with different levels of resolution: 16S rDNA restriction analysis (ARDRA), 16S-23S rDNA intergenic spacer-restriction fragment length polymorphism (ITS-RFLP) analysis, and repetitive extragenic palindromic PCR genomic fingerprinting with a BOX primer

Abstract:
The major outer-membrane protein of Pseudomonas, OprF, is multifunctional. It is a non-specific porin that plays a role in maintenance of cell shape, in growth in a low-osmolarity environment, and in adhesion to various supports or molecules. OprF has been studied extensively for its utility as a vaccine component, its role in antimicrobial drug resistance, and its porin function. The authors have previously shown important differences between the OprF and 16S rDNA phylogenies: Pseudomonas fluorescens isolates split into two quite separate clusters, probably according to their ecological niche

Abstract:
A bacterial strain 3-1 which could use ACC as the sole nitrogen sources was isolated from Chinese chives rhizosphere soil. The strain was identified as Pseudomonas fluorescent, according to the results of morphology, physiology and the phylogenetical analyses of 16S rDNA sequence. The ACC deaminase activity of Pseudomonas fluorescent 3-1 strain had high level of ACC deaminase activity, 2.63±0.12 µmol α-KA • (mg Pr •h)-1 . The procedure described here was relatively straight forward to isolate and characterize new PGPR strains. This bacterium may be used to facilitate the growth of Porrum.

Abstract:
On a global basis, trace-metal pollution is one of the most pervasive environmental problems. It is particularly difficult to prevent or clean up because the metals are toxic in their elemental form and cannot be decomposed. Bioremediation has been shown to be a powerful system for heavy metal pollution clean up and prevention. In this work, we characterized the cadmium (Cd)-resistant bacteria isolated from rice field soil downstream from zinc (Zn) mineralized area which the owners were contaminated at high level of cadmium content in their blood (&amp;gt;10 μgCd/g creatinine).
