| 概要 |
Previous studies have already reported that cellular fatty acid analysis is a useful taxonomic tool for classifying and identifying Bradyrhizobium strains, including B. japonicum, B. elkanii and Brady...rhizobium sp. obtained from mungbean. In this study, the existence of species-specific fatty acids, 16:1ω5cis, 17:0 cycro and 19:0 ω8sis were remarked as the identification profiles within B. japonicum and B.elkanii. Direct detectin of B. japonicum and B. elksnii from plant grown ssoils were performed by whole cellular fatty acid analysis combined with plant baiting technique. Tested plant materials, soybean, contaminated soils to single strain and mixture of B. japonicum and B. elkanii, and the natural infested soils were prepared for whole cellular fatty acid analysis. Bacteria trap experiment with plant baiting technique revealed that whole cellular fatty acid analysis was effectively detected B. japonicum and B.elkanii from all soil materials by using syobean plant.続きを見る
