Abstract

Paraburkholderia bengalensis sp. nov. strain IR64_4_BI was isolated from rice roots cultivated in Madhyamgram field station of Bose Institute, West Bengal, India. IR64_4_BI is a Gram-negative, motile, nitrate-reducing, nitrogen-fixing bacterium. Whole-cell fatty acid analyses of IR64_4_BI show C16:0, summed feature 8 (comprising C18:1ω7c and/or C18:1 ω 6c) and summed feature 3(C16:1 w7c/C16:1 w6c or C16:1 ω 7c/C16:1 ω 6c) were the predominant fatty acids. 16S rRNA phylogeny showed that it was most similar to P. phymatum STM815T (98.5% identity), P. terrae KMY02T (98.44% identity) and P. hospita LMG 20598T (98.32% identity). The Average Nucleotide Identity-BLAST (ANIb) of P. bengalensis IR64_4_BI with P. hospita DSM 17164T, P. terrae DSM 17804T, P. phymatum STM815T and P. hospita LMG 20598T was 83.11, 83.52, 84.5 and 83.12% respectively. Comparison of genome sequence of IR64_4_BI with other species of Paraburkholderia using the Multi-locus species tree software show that P. bengalensis IR64_4_BI is a novel species. The ability of P. bengalensis IR64_4_BI to survive on nitrogen-free medium under microaerophilic conditions and the abundance of nitrogen metabolism-related genes makes this strain a potential candidate for developing a nitrogen-fixing system in rice. Based on genotypic, phenotypic and chemotaxonomic studies, we propose that IR64_4_BI (= MTCC 13051 = JCM 34777) is a new species of Paraburkholderia which has been assigned as Paraburkholderia bengalensis sp.nov.
