title: A method for the isolation of asporogenic mutants of Bacillus thuringiensis.
abstract: Asporogenic and oligosporogenic mutants of Bacillus thuringiensis can be isolated by streaking the bacteria onto a solid medium, incubating at 42 degrees C, and picking small, raised areas of growth which appear on the streaks after 48 h.
