“…DD16 produced the highest [IAA] of 1.543 mgL -1 and followed by DD9 with [IAA] of 1.39 mgL -1 . Bacterial endophytes could accelerate and enhance plant growth through mechanism such as nitrogen fixation, phosphate solubilization, phytohormones… As discussed above, most bacterial endophytes of legume plants including Sesbania ssp were isolated from nodules and were described as rhizobia [2][3][4][5][6][7][8][9][10][11][12][13]. The results of investigation on plant growth promoting activities of bacterial isolates from Sesbania bispinosa showed that 20 isolates collected from the root nodules of Sesbania bispinosa could grew on nitrogen free medium and gave positive effects on ammonia production test [30].…”

The study aimed to isolate and characterize endophytic bacteria associated with Sesbania sesban (L.) Merr. collected in Tan Hung district, Long An province, Vietnam. Bacterial endophytes were isolated and screened capacity of plant growth promotion by using LGI, Burks’ nitrogen free, NBRIP medium. Quantifying bacterial strain’s probability of nitrogen fixation, phosphate solubilization and IAA production was based on colorimetric methods. Isolates with the most potential of nitrogen fixation, phosphate solubilization were identified by using MALDI-TOF Mass Spectrometry. The results were that eighteen bacterial endophytes were isolated from Sesbania sesban (L.) Merr. roots. They had characteristics of promoting plant growth by nitrogen fixation, phosphate solubilization and IAA biosynthesis. DD2 and DD18 with the best capacity of nitrogen fixation and phosphate solubilization were identified as Klesiella pneumonia and Priestia megaterium, respectively. Both were previously reported as plant growth promotion bacteria.

“…Diazotrophic bacteria symbiosing with Sesbania ssp. belonged to genus Rhizobium, Mesorhizobium, Sinorhizobium, Azorhizobium, Neorhizobium, Bradyrhizobium, Ensifer and Agrobacterium [2,3]. Neorhizobium huautlense interacted symbiotically with Sesbania herbacea [4]; Azorhizobium caulinodans and Bradyrhizobium sp.…”
