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

ABSTRACT

The bacterial strains IMB-1(T) and CC495(T), which are capable of growth on methyl chloride (CH(3)Cl, chloromethane) and methyl bromide (CH(3)Br, bromomethane), were isolated from agricultural soil in California fumigated with CH(3)Br, 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-1(T)=ATCC 202197(T)=CIP 108660(T)=CCUG 50580(T); strains ER2 and C147) and Aminobacter lissarensis sp. nov. (type strain CC495(T)=NCIMB 13798(T)=CIP 108661(T)=CCUG 50579(T)) are proposed.
