Applying PGPB (Plant Growth-Promoting Bacteria) as bioinoculant under the excessive and continuous use of chemical fertilizer, pesticide, and herbicide need to be highlighted nowadays. One of the most beneficial PGPB is potassium-solubilizing rhizobacteria. Potassium is one of the elements that plant absorbs in a large amounts along with nitrogen. Soil in various regions of Indonesia have low potassium solubility. Therefore, finding the best novel isolates contributing to potassium solubilization need to be carried out continually. The aim of this study is to find potassium-solubilizing bacteria from two different rhizospheres (banana and chili plant) in Leuwikopo Experimental Garden and a cow manure in Cattle Pen, IPB University. To obtain the potassium-solubilizing isolates, we observed and characterized the best growing isolates and measured the solubilizing zone on Alexandrov agar medium. Three out of 10 isolates were selected and tested their pathogenicity on tobacco leave. Solubilization index of three isolates from the highest to the lowest were MPK P (3.07), MPK KT (3.03), and MPK C (2.63), respectively. Necrotic on tobacco leave after isolates treatment showed negative result which means that the three isolates were not pathogenic to plant host. The isolates are recommended to be used as bioinoculant both in greenhouse and field plants which lack of potassium availability in soil.

In arid ecosystems environmental factors such as geoclimatic conditions and agricultural practices are of major importance in shaping the diversity and functionality of plant-associated bacterial communities. Assessing the influence of such factors is a key to understand (i) the driving forces determining the shape of root-associated bacterial communities and (ii) the plant growth promoting (PGP) services they provide. Desert oasis environment was chosen as model ecosystem where agriculture is possible by the microclimate determined by the date palm cultivation. The bacterial communities in the soil fractions associated with the root system of date palms cultivated in seven oases in Tunisia were assessed by culture-independent and dependent approaches. According to 16S rRNA gene PCR-DGGE fingerprinting, the shapes of the date palm rhizosphere bacterial communities correlate with geoclimatic features along a north-south aridity transect. Despite the fact that the date palm root bacterial community structure was strongly influenced by macroecological factors, the potential rhizosphere services reflected in the PGP traits of isolates screenedin vitrowere conserved among the different oases. Such services were exerted by the 83% of the screened isolates. The comparable numbers and types of PGP traits indicate their importance in maintaining the plant functional homeostasis despite the different environmental selection pressures.

Two bacterial strains that amplified part of the nifH gene, RP1p and RP2p, belonging to the genus Enterobacter and Serratia, were isolated from the rhizoplane of Lupinus albescens. These bacteria are Gram-negative, rod-shaped, motile, facultative anaerobic, and fast-growing; the colonies reach diameters of 3-4 mm within 24 h of incubation at 28 ºC. The bacteria were also able to grow at temperatures as high as 40 ºC, in the presence of high (2-3 % w/v) NaCl concentrations and pH 4 -10. Strain RP1p was able to utilize 10 of 14 C sources, while RP2p utilized nine. The isolates produced siderophores and indolic compounds, but none of them was able to solubilize phosphate. Inoculation of L. albescens with RP1p and RP2p strains resulted in a significant increase in plant dry matter, indicating the plant-growth-promoting abilities of these bacteria.
