“…Sequence analysis revealed the presence of several antibiotic resistance genes (ARG) encoding metallo-beta-lactamase, chloramphenicol, and aminoglycoside phosphotransferase. Other Serratia strains such as S. marcescens FGI94, S. fonticola DSM 4576, and S. ficaria showed also multi-resistances to antibiotics [114][115][116]. Thus, the emerging question is how to consider the two-blade weapons of PGP bacterial strains exhibiting intrinsic resistance to several antibiotics.…”

Halotolerant Endophytic Bacterium Serratia rubidaea ED1 Enhances Phosphate Solubilization and Promotes Seed Germination

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.

“…Obtaining detailed taxonomic information on these fungal flora will provide fundamental information to develop effective bio-control strategies aimed at emerging problems such as B. agrestis . Meanwhile, Kosakonia radicincitans [ 39 40 ], Rhodococcus erythropolis [ 41 ], and Serratia fonticola [ 42 43 ] have been reported to have beneficial effects for crop plants or agricultural environments. Further studies will be required to determine the taxonomic relationships of these isolates.…”

Cutaneous Microflora from Geographically Isolated Groups ofBradysia agrestis, an Insect Vector of Diverse Plant Pathogens

et al. 2017

Larvae of Bradysia agrestis, an insect vector that transports plant pathogens, were sampled from geographically isolated regions in Korea to identify their cutaneous fungal and bacterial flora. Sampled areas were chosen within the distribution range of B. agrestis; each site was more than 91 km apart to ensure geographical segregation. We isolated 76 microbial (fungi and bacteria) strains (site 1, 29; site 2, 29; site 3, 18 strains) that were identified on the basis of morphological differences. Species identification was molecularly confirmed by determination of universal fungal internal transcribed spacer and bacterial 16S rRNA gene sequences in comparison to sequences in the EzTaxon database and the NCBI GenBank database, and their phylogenetic relationships were determined. The fungal isolates belonged to 2 phyla, 5 classes, and 7 genera; bacterial species belonged to 23 genera and 32 species. Microbial diversity differed significantly among the geographical groups with respect to Margalef's richness (3.9, 3.6, and 4.5), Menhinick's index (2.65, 2.46, and 3.30), Simpson's index (0.06, 0.12, and 0.01), and Shannon's index (2.50, 2.17, and 2.58). Although the microbial genera distribution or diversity values clearly varied among geographical groups, common genera were identified in all groups, including the fungal genus Cladosporium, and the bacterial genera Bacillus and Rhodococcus. According to classic principles of co-evolutionary relationship, these genera might have a closer association with their host insect vector B. agrestis than other genera identified. Some cutaneous bacterial genera (e.g., Pseudomonas) displaying weak interdependency with insect vectors may be hazardous to agricultural environments via mechanical transmission via B. agrestis. This study provides comprehensive information regarding the cutaneous microflora of B. agrestis, which can help in the control of such pests for crop management.

“…They enhance crop yields and ecological balance in the agroecosystem by facilitating the uptake of nutrients from the environment. They also produce secondary metabolites such as siderophores and phytohormone and protect the plants against pathogenic infections [39][40][41]. Some strains of Serratia including, Serratia plymuthica HRO-C48 produce the halogenated secondary metabolite pyrrolnitrin which is a promising agricultural fungicide [42][43][44].…”
