Six isolates of Burkholderia were obtained from rhizosphere soils of rice grown in tropical lowlands of South Assam, India. Among the identified Burkholderia isolates, SDSA-I10/1 has shown higher nitrogen fixing potential and it was selected for 16S rDNA sequencing. The isolate SDSA-I10/1 showed highest resemblance to Burkholderia caribensis MWAP84 (Y17011) and hence, identified as Burkholderia caribensis strain SDSA-I10/1 (GU372342). Inoculation of this strain improved the growth and yield parameters of rice significantly over uninoculated control plants, thus it may be used as indigenous microbial inoculant for intensive rice cropping in tropical lowlands.
Key words: Burkholderia caribensis strain SDSA-I10/1, 16S rDNA sequence, biofertilizer, Diazotroph, nitrogenase activity, tropical lowland.
