Use of Plant growth promoting rhizobacteria (PGPR) is a promising strategy to improve the crop production under optimal or sub-optimal conditions. In the present study, five diazotrophic salt tolerant bacteria were isolated from the roots of a halophyte, Arthrocnemum indicum. The isolates were partially characterized in vitro for plant growth promoting traits and evaluated for their potential t...

application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. therefore, scientists are searching for alternatives to antibiotics nowadays. medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. in this paper, the benefits of...

To date, several bacterial species have been described as mineral-weathering agents which improve plant nutrition and growth. However, the possible relationships between mineral-weathering potential, taxonomic identity, and metabolic ability have not been investigated thus far. In this study, we characterized a collection of 61 bacterial strains isolated from Scleroderma citrinum mycorrhizae, t...

the effect of different isolates of trichoderma namely t. virens t65, t virens t90, t. virens t96, t. virens t122, t. brevicompactum t146, t. koningiopsis t149, t. viridecense t150, t. koningii as well as two trichodermin b and subtilin commercial bioproducts on growth promotion in wheat were studied through seed coating method in a compeletly randomized design in a glasshouse experiment. the i...

Plant growth-promoting rhizobacteria (PGPR) are an important bacterial resource as biofertilizers, which can promote plant growth and increase crop yields. In this study, isolation, characterization, its effect on promotion were assessed by isolating PGPR using soil samples collected from Jimma, Ethiopia. Out of 10 isolates, three them (JEC3, JEC4, JEC7) exhibited PSB traits in Pikovskaya media...

Plant growth-promoting bacteria can greatly assist sustainable farming by improving plant health and biomass while reducing fertilizer use. The plant-microorganism-environment interaction is an open and complex system, and despite the active research in the area, patterns in root ecology are elusive. Here, we simultaneously analyzed the plant growth-promoting bacteria datasets from seven indepe...

The exploitation of the association between plants and microorganisms is a promising approach able to boost natural attenuation processes for soil clean-up in vast polluted areas characterized by mixed chemical contamination. We aimed to explore the selection of root-associated bacterial communities driven by different plant species spontaneously established in abandoned agricultural soils with...

A group of twenty faba bean rhizobial isolates was collected from two Egyptian Governorates (Dakahlia and Damitta). The were further morphologically physiologically characterized to check their growth symbiotic performance on plants. According remarkable lab pots tests, five (Rh 32, Rh 6-A, 3-4, RL3, 8-A) selected subjected biochemical molecular characterizations. Genetic profiling the promisin...

Endophytic bacteria were isolated from stems of Eucalyptus spp (Eucalyptus citriodora, E. grandis, E. urophylla, E. camaldulensis, E. torelliana, E. pellita, and a hybrid of E. grandis and E. urophylla) cultivated at two sites; they were characterized by RAPD and amplified rDNA restriction analysis (ARDRA). Endophytic bacteria were more frequently isolated from E. grandis and E. pellita. The 76...

Biofertilizer is a relatively safer, environmentally friendly and cost-effective approach as an alternative to reduce chemical fertilizer usage. The selection of bacterial strains with multiple beneficial characteristics are important to maximize the effectiveness on the host plant. Due to aforementioned interest, several Plant Growth-Promoting Rhizobacterial (PGPR) and rhizobial strains were i...
