Culturable endophytic Pseudomonas fluorescens Z1B4 isolated from Zanthoxylum alatum Roxb. with stress-tolerance and plant growth-promoting potential.

ABSTRACT: Endophytes are an important constituent of sustainable agriculture because of their ability to produce a large number of agriculturally important metabolites. A salt-tolerant fluorescent green pigment-producing endophytic bacterium was isolated on 2.5% NaCl-supplemented nutrient agar from the leaf samples of Zanthoxylum alatum Roxb. The isolate Z1B4 was identified as Pseudomonas fluorescens based on morphological features, fatty acid methyl ester analysis, biochemical tests, and 16S rRNA gene sequencing. P. fluorescens Z1B4 showed positive results for tricalcium phosphate solubilization; 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity; and production of auxins, siderophores, hydrogen cyanide, and ammonia. P. fluorescens Z1B4 also showed strong antagon
