16S rRNA Gene Sequencing and Phylogeny Analysis Revealed the Presence of Beneficial Bacteria in the Rhizosphere of Eggplant (Solanum melongena) from Malda (West Bengal, India)
Keywords:
Rhizosphere soil, Eggplant, Lactic acid bacteria, Limosilactobacillus fermentum, Bifidobacterium animalis subsp. lactisAbstract
Lactic acid bacteria have been used in agricultural practices with promising potential as soil health-promoting microorganisms. Isolation of lactic acid bacteria from the rhizosphere soil of various crops including brinjal (eggplant), Solanum melongena has been reported from different parts of the world. No such reports are available in our region (Malda, India). In this study, we have isolated and characterized lactic acid bacteria from Solanum melongena rhizosphere. The rhizosphere soils from the eggplant cultivars (Jhiloria, Chandtara, Jotshna) were processed microbiologically, and three lactic acid bacteria were isolated. The16S rRNA gene sequencing and phylogeny analysis confirmed the identities of lactic acid bacteria as Limosilactobacillus fermentum isolated from the rhizosphere of Jhiloria and Chandtara varieties of eggplant, while the isolate from the rhizosphere of the Jotshna variety of eggplant was identified as Bifidobacterium animalis subsp. lactis. Thus, the presence of beneficial bacteria (Limosilactobacillus fermentum and Bifidobacterium animalis subsp. lactis) in the rhizosphere of crop plants might help improve soil health thereby enhancing crop production.
