Plant growth-promoting rhizobacteria (PGPR) with antagonistic activity toward plant pathogenic fungi are valuable candidates for the development of novel protection products based on biocontrol activity. The very first step in formulation such is to screen potential effectiveness selected microorganism(s). In this study, non-pathogenic were isolated from rhizosphere tomato plants and evaluated ...

Copper (Cu) is an essential element, however it’s excess into the environment causes detrimental effect on plant and risks for public health. Four Cu drought tolerant 1-aminocyclopropane-1-carboxylate (ACC) deaminase producing rhizobacteria were isolated from roots of Trifolium repens L. growing smelter contaminated soils, characterized identified based 16S rRNA gene sequencing. A consortium hi...

In Arabidopsis (Arabidopsis thaliana), malate released into the rhizosphere has various roles, such as detoxifying rhizotoxic aluminum (Al) and recruiting beneficial rhizobacteria that induce plant immunity. ALUMINUM-ACTIVATED MALATE TRANSPORTER1 (AtALMT1) is a critical gene in these responses, but its regulatory mechanisms remain unclear. To explore the mechanism of the multiple responses of A...

Soil bacteria belonging to the genus Azotobacter, Pantoea and some unidentified soil isolates were tested in vitro for phytohormone production under laboratory and soil conditions. The German wheat variety Munk was inoculated by several soil bacteria with exogenously applied hormones (IAA, 2,4-D) and a flavonoid (naringenin) with a half of the amount of recommended doses of fertilizers under gr...

Latar Belakang: Tempat pemakaman umum (TPU) adalah lokasi penguburan jenazah dan terjadi dekomposisi jasad secara aktif menghasilkan nutrisi mineral tanah yang mendukung pertumbuhan makhluk hidup di sekitarnya termasuk bakteri pohon Kamboja. Pohon Kamboja dikenal tahan terhadap cekaman biotik maupun abiotik mumgkin dipengaruhi keberadaan rizosfer sebagai plant growth promoting rhizobacteria (PG...

The current study focused on enumerating the potential plant growth-promoting rhizobacteria (PGPR) from rhizosphere of Arachis hypogaea L. Among several colonies grown an Ashby plate, only seven isolates (Ah1 to Ah7) had nitrogen-fixing potential. Ah4 isolate showed higher for (PGP) activities than other isolates. This was recognized as Kosakonia sp. MGR1 through 16S rRNA sequencing with 99.7% ...

in order to study the effect of synorhizobium meliloti on growth and nutrients uptake of sesame, a greenhouse test was carried out. the first isolates investigated in iaa and siderophore producing and their ability in solubilizing inorganic phosphates. the results showed that all of isolates were able to produce auxin with different among. the maximum amount of iaa production was 59.5 g ml-1 th...

Abstract The consortium of bacteria that inhabit the rhizosphere, acting as plant growth promoting rhizobacteria is known indigenous rhizobacteria. Rhizobacteria can produce chemical compounds protect plants from pathogens and various plant-disturbing organisms. Optimization yield patchouli be done by utilizing potential derived rhizosphere. This study aims to obtain capable producing secondary...

Many farmers use organic fertilizers to preserve the environment, but unfortunately, it’s not as effective chemical fertilizers. In recent years, discovery of plant growth-promoting rhizobacteria (PGPR) has gained some attraction. PGPR have abilities promote growth efficiently, including corn plants. Corn (Zea mays L.) is a staple food needed in large quantities. Our results show that bacteria ...
