“…Here, IAA production by Serratia rubidaea ED1 was seen even in the absence of L-Tryptophan supplementation (Figure 5). However, in L-tryptophan-supplemented broth, production of IAA increased significantly (Figure 5), corroborating previous finding on Serratia species including S. rubidaea highlighting that IAA signaling pathways are either auxin-dependent, auxin-independent, or tryptophan-independent [78,98]. Besides, other halotolerant bacteria species isolated from halophytic plant in coastal soils in Korea, enhanced plant growth under saline stress.…”

“…In the present study, we identified an endophytic S. rubidaea ED1 bacterium from quinoa roots endosphere, a plant endowed with many phyto-beneficial attributes facing extreme growth stresses. Some PGP results of Serratia rubidaea ED1 were expected as they were reported in Serratia rubidaea alongside S. plymuthica, S. liquefaciens, S. proteamaculans, and S. nematodiphila, isolated from various environments niches [78]. PGP attributes of Serratia rubidaea (NR114716) associated with Origanum plants was reported for IAA and siderophores production, P solubilization, ACC-deaminase activity, and N fixation [79].…”

Quinoa is renowned for its nutritional value and ability to withstand harsh environmental conditions such as salinity. In the present work, we isolated 34 phosphate solubilizing endophytic bacteria associated with the roots of quinoa plants. Based on phosphate solubilization efficiency and biochemical characterization, we selected one isolate named ED1. Ribotyping using partial 16S RNA gene analysis revealed that the selected isolate shares 99.7% identity with Serratia rubidaea. Plant growth promoting (PGP) studies showed that the ED1 strain solubilized complexed forms of phosphate (Ca3(PO4)2). Zinc release from ZnO, Zn3(PO4)2, or ZnCO3 revealed the efficient ZnO solubilization by the ED1 strain. Except for proteases, the strain ED1 produced siderophores, cellulase, ammonia and exhibited oligonitrophilic features. Indole acetic acid (IAA) production was detected with and without the L-tryptophan precursor. Next, we demonstrated that the ED1 strain tolerated 1.5 M NaCl final concentration and exhibited intrinsic resistance to seven antibiotics frequently prescribed for medical use. Moreover, we found that ED1 strain withstood 2 mg/L of Cadmium and 1 mg/L of either Nickel or Copper. Furthermore, we observed that S. rubidaea ED1 stimulated quinoa seeds germination and seedlings growth under salt stress conditions. Lastly, we discuss the advantages versus disadvantages of applying the S. rubidaea ED1 strain as a beneficial agent for salty and/or heavy metals contaminated soils.

“…The results that we obtained showed that strains affiliated with S. grimosii, B. subtilis, and B. tequilensis displayed the strongest growth inhibition in an in vitro dual culture against F. culmorum and F. oxysporum. These results confirm that S. grimosii, B. subtilis, and B. tequilensis strains are useful antagonists of plant fungal pathogens [27,33]. Their antagonistic activities are known to be related to the synthesis and release of a broad range of secondary metabolites with antimicrobial activities.…”

The exploration of certain microbial resources such as beneficial endophytic microorganisms is considered a promising strategy for the discovery of new antimicrobial compounds for the pharmaceutical industries and agriculture. Thirty-one endophytic bacterial strains affiliated with Bacillus, Janthinobacterium, Yokenella, Enterobacter, Pseudomonas, Serratia, and Microbacterium were previously isolated from vetiver (Chrysopogon zizanioides (L.) Roberty) roots. These endophytes showed antifungal activity against Fusarium graminearum and could be a source of antimicrobial metabolites. In this study, in particular, using high-throughput screening, we analyzed their antagonistic activities and those of their cell-free culture supernatants against three species of Fusarium plant pathogens, a bacterial strain of Escherichia coli, and a yeast strain of Saccharomyces cerevisiae, as well as their capacity to produce lipopeptides. The results showed that the culture supernatants of four strains close to B. subtilis species exhibited antimicrobial activities against Fusarium species and E. coli. Using mass spectrometry analyses, we identified two groups of lipopeptides (surfactins and plipastatins) in their culture supernatants. Whole-genome sequencing confirmed that these bacteria possess NRPS gene clusters for surfactin and plipastatin. In vitro tests confirmed the inhibitory effect of plipastatin alone or in combination with surfactin against the three Fusarium species.

“…A espécie Serratia pertence à família Enterobacteriaceae são relatadas como endófitas abundante na rizosfera das plantas. Tais microrganismos são capazes de promover o crescimento das plantas hospedeira, alto potencial de biocontrole com base antibiose (produção de prodigiosina e pirrolnitrina), capacidade de produção de enzimas líticas (quitinases e β-1,3-glucanases) que agem contra fungos patogênicos de solo (Kshetri et al,2019).…”

“…Adicionalmente, os benefícios ocasionados dentro dos tecidos das plantas englobam a absorção de nutrientes, como o fósforo, por meio da solubilização do fosfato e da produção de sideróforos e na sintetização de fitohormonios, como o ácido indol-3acético (AIA) (Kshetri et al,2019).…”
