Plant growth promoting rhizobacteria (PGPR) have been extensively employed as biofertilizers to enhance the soil nutrition for several crop plants. Rhizobacteria with beneficial effects plants could therefore be used reduce dependence on synthetic chemical fertilizers in conventional agriculture. Within this study, we explored isolation of potential PGPR groundnut from agricultural fields Saura...

Background: Plant growth promoting rhizobacteria (PGPR) is beneficial bacteria that are colonizing in the plant root and enhance into growth. The use of PGPR steadily increasing agriculture offers an attractive way to replace chemical fertilizers pesticides. In this present study, were isolated from marine sediment, water coastal sand dune plants. From that, 480 different bacterial strains isol...

HIGHLIGHTS Rhizobacteria (Azotobacter spp.) have improved the quality and quantity of safflower seed protein.Protein quality was confirmed by SDS-PAGE and new bands were found in response to different combinations of rhizobacteria and lower doses of fertilizers.The PGPR application has reduced the use of fertilizers upto 50%. Protein is an essential part of the human diet. The aim of this prese...

We have developed a new assay that differentiates between indoleacetic acid (IAA)-producing and -nonproducing bacteria on a colony plate lift. Medium supplemented with 5 mM L-tryptophan is inoculated with isolates of interest, overlaid with a nitrocellulose membrane, and then incubated until bacterial colonies reach 1 to 2 mm in diameter. The membrane is removed to a filter paper saturated with...

Corn productivity in Indonesia is still relatively low compared with other countries. Therefore, it necessary to increase the of corn by using rhizobacteria, which have multiple traits. This study was conducted obtain indigenous rhizobacteria Bali that traits, can produce indoleacetic acid (IAA), fix nitrogen from atmosphere, siderophores, colonize roots, seed germination, and promote growth co...

Plant growth promoting rhizobacteria produce chemical compounds with different benefits for the plant. Among them, HCN is recognized as a biocontrol agent, based on its ascribed toxicity against plant pathogens. Based on several past studies questioning the validity of this hypothesis, we have re-addressed the issue by designing a new set of in vitro experiments, to test if HCN-producing rhizob...

Abstract Salinity stress is a serious abiotic that affects crop quality and production. Rhizospheric microbes have immense potential in synthesizing releasing various compounds regulate plant growth soil physicochemical properties. The aim of the present study was to evaluate efficacy indole-3-acetic acid (IAA)-producing rhizobacteria as biofertilizers under salt stress. Among isolated strains ...

Indole-3-acetic acid (IAA) was detected in the ether extracts of culture filtrates of indigotin-producing strains of the basidiomycete Schizophyllum commune. Several solvents, known to give distinctly different R(F) values for IAA, and 3 location reagents gave identical results with synthetic IAA and IAA found in the extract. Confirmation was obtained by the Avena straight growth test, split pe...
