Aminobacter ciceronei sp. nov. and Aminobacter lissarensis sp. nov., isolated from various terrestrial environments

The bacterial strains IMB-1T and CC495T, which are capable of growth on methyl chloride (CH3Cl, chloromethane) and methyl bromide (CH3Br, bromomethane), were isolated from agricultural soil in California fumigated with CH3Br, and woodland soil in Northern Ireland, respectively. Two pesticide-/herbicide-degrading bacteria, strains ER2 and C147, were isolated from agricultural soil in Canada. Strain ER2 degrades N-methyl carbamate insecticides, and strain C147 degrades triazine herbicides widely used in agriculture. On the basis of their morphological, physiological and genotypic characteristics, these four strains are considered to represent two novel species of the genus Aminobacter, for which the names Aminobacter ciceronei sp. nov. (type strain IMB-1T=ATCC 202197T=CIP 108660T=CCUG 50580T; strains ER2 and C147) and Aminobacter lissarensis sp. nov. (type strain CC495T=NCIMB 13798T=CIP 108661T=CCUG 50579T) are proposed.
