New symbiotic betarhizobia from Brazil

In two interesting papers, the group leaded by Dr. Fatima Moreira (Universidade Federal de Lavras, Campus UFLA, Lavras, Minas Gerais, Brazil), in collaboration with Dr. Peter Vandamme (Laboratory of Microbiology, Universiteit Gent, Ghent, Belgium) report on the symbiotic N2-fixing capacity of Burkholderia contaminans, B. fungorum and B. lata on different hosts (Phaseolus vulgaris, Indigofera suffruticosa,  Macroptilium atropurpureum and Pithecellobium sp.) growing in Brazilian Amazon region (PUMBMED). The second paper reports on the isolation of N2-fixing ability of Cupriavidus necator strains recovered P. vulgaris and Leucaena leucocephala from Brazil. These strains did also nodulate Mimosa caesalpiniaefolia, M. atropurpureum, and Vigna unguiculata). The authors demonstrate the presence of nifH and nodC genes in all of their isolates (PUBMED).
