[Susceptibility of archaea to the antibiotic effect of the parasporal inclusion proteins from Bacillus thuringiensis subspecies].
The proteins of parasporal inclusions from three Bacillus thuringiensis subspecies (kurstaki, amagiensis, and monterrey) inhibited growth of methanogenic archaea of two species belonging to two genera, Methanobrevibacter arboriphilus and Methanosarcina barkeri. The minimal inhibitory concentrations of these proteins were 20 to 50 micrograms/ml. Lysozyme exhibited similar bactericidal effect on archaea. The perspective of comparative studies on the effect of polyfunctional proteins on bacteria and archaea is discussed.
