Plant growth promoting rhizobacteria (PGPR) have originally been defined as root-colonizing bacteria that cause either plant growth promotion or biological control of plant diseases. The mechanisms by which PGPR promote plant growth are not fully understood, but it is believed that the plant growth promoting rhizobacteria enhance plant growth and yield either by direct or indirect mechanisms. T...

Plant growth-promoting rhizobacteria strains from special formulations have been used to optimize eucalyptus cutting production. To undertake quality control for the formulated products, the rhizobacterial strains should be characterized to assess their purity and authentication. In the present study, we characterized nine strains of rhizobacteria, including three Bacillus subtilis (S1, S2 and ...

Background: Lactic acid bacteria are regarded the most important concerning food fermentation, pharmaceutical and special dietary applications. Strains have been isolated from environments rich in available carbohydrate substrates, such as feed, but also human animal cavities sewage plant material. Besides lactic acid, other side products include acetate, ethanol, CO2, formate succinate. The ad...

Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance plant growth by a wide variety of mechanisms like phosphate solubilization, siderophore production, biological nitrogen fixation, rhizosphere engineering, production of 1-Aminocyclopropane-1-carboxylate deaminase (ACC), quorum sensing (QS) signal interference and inhibition of biofilm formation, phytohormo...

the rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (pgpr). in this study, the isolation andidentification of rhizobacteria from orange (citrus sinensis) orchards using 16s rrna gene, as well asbiological and biochemical assays is reported. analysis of 16s rrna gene was confirmed bybiological and ...

The use of plant growth-promoting rhizobacteria (PGPR) is a sustainable way for efficient absorption and utilization nutrients by crop species to enhance growth yield persistence against biotic abiotic stresses. However, the PGPRs in drought tolerant crops such as foxtail millet limited because low adaptability moisture conditions. In this study, acclimatised conditions, were isolated from rhiz...

In their natural environment, plants live in close interaction with complex populations of microorganisms, including rhizobacteria species commonly referred to as ‘Plant Growth Promoting Rhizobacte...

The base temperature for germination of corn is approximately 10°C, which results in slow germination and emergence of corn crops sown into cool soils. The effects of plant-growth-promoting rhizobacteria (PGPR) and kinetin on grain and sweet corn emergence, plant growth and yield were studied under short season conditions in 1996 and 1997. Two PGPR strains (Serratia proteamaculans 1-102 and Ser...

This study was conducted to investigate the effects of some plant growth-promoting rhizobacteria (PGPR) on arbuscular mycorrhizal fungi (AMF) formation [Brassica oleracea (cauliflower), Spinacia (spinach) ,and Urtica urens (stinging nettle)] belonging Brassicaceae, Chenopodiaceae and Urticaceae families, which are known have a negative influence symbiotic life with AMF. Two PGPR isolates that c...
