“…This study for the first time isolated very high salinity-tolerant bacteria associated with rice cultivated in the salinity affected areas of Bangladesh. Enhancement of salinity tolerance in crop plants by the application of the PGPB has been reported earlier [11]. To be effective in enhancing salinity tolerance by the plant probiotic bacteria, the isolate must be salinity tolerant.…”

“…Similar to other PGPB, Brevibacterium spp. can produce significant amounts of ACC deaminase [36], and it has been found that inoculation of plants with ACC deaminase-producing bacteria increases root biomass and produce longer roots [11,44]. High production of antioxidant enzymes reduces the generation of hydrogen peroxide under salt stress [45].…”

“…For the collection of potential salt-tolerant bacteria, different plant parts such as the leaf, root, and rhizospheric soil were taken. The bacteria were isolated from plant parts using protocols described earlier [11,50]. Six-fold serial dilution was prepared in autoclaved water [51].…”

“…Since all of these strategies are lengthy and cost-intensive [8][9][10], there is a need for research on developing a novel, sustainable, and cost-effective approach. In this regard, the role of microorganisms, especially plant growth-promoting bacteria (PGPB), is a very important for enhancing salinity stress tolerance in crop plants [11].…”

“…The PGPB has remarkable impacts to ensure normal growth and development of plants under salinity [22]. A good number of bacterial strains, such as Bacillus spp., Pseudomonas spp., Frankia spp., and Rhizobia spp., have been identified that are capable of aiding plants to tolerate various environmental stresses including salinity [11,22,23]. In addition, the magnificent benefits of the PGPB have developed a large trading platform; the commercialization of PGPB has been reported by Vessey [24] and Lucy et al [25].…”

Soil salinity has emerged as a serious issue for food security due to global climate change. It is estimated that currently about 62 million hectares or 20 percent of the world’s irrigated land is affected by salinity. Salinity is a serious problem in the coastal areas of Bangladesh. Isolation of salt-tolerant plant growth-promoting bacteria (PGPB) and applying them as bioinoculants in crop plants are considered promising and effective biotechnological approaches to combat soil salinity. This study aimed to screen salt-tolerant PGPB from the root, leaf, and rhizospheric soils of rice plants collected from salt-affected coastal areas including Chattogram, Noakhali, Lakshmipur, and Cox’s Bazar districts of Bangladesh and evaluated their performances on the seedling growth of rice. Out of forty-one salinity-tolerant bacterial isolates screened, Brevibacterium sediminis showed salinity tolerance up to 12% NaCl (w/v). In vitro bioassay revealed that B. sediminis promoted the seedling growth of rice cv. BRRI dhan29 (salinity susceptible) and BINAdhan-10 (salinity tolerant), and the growth-promoting effects were higher in BINAdhan-10. This study for the first time identified B. sediminis strain IBGE3C as a salt-tolerant PGPB from a widely cultivated rice variety, BRRI dhan28 in the Lakshmipur district of Bangladesh. Our results suggest that salt-tolerant PGPB isolated from the root, leaf, and rhizospheric soil of rice plants could be used as a low cost and environmentally friendly option for overcoming the detrimental effects of salt stress on rice plants in the southern coastal regions of Bangladesh. However, further studies are needed for assessing the efficacy of B. sediminis on enhancement of salinity tolerance, and growth and yield of rice under salinity stressed conditions.
