VILAS-BOAS, Gislayne T. et al. Isolation and partial characterization of a mutant of Bacillus thuringiensis producing melanin. Braz. J. Microbiol. [online]. 2005, vol.36, n.3, pp. 271-274. ISSN 1517-8382. http://dx.doi.org/10.1590/S1517-83822005000300012.
A mutant (407-P) of Bacillus thuringiensis subsp. thuringiensis strain 407 producing a melanin was obtained after treatment with the mutagenic agent ethyl-methane-sulfonate. Several microbiological and biochemical properties of the two strains were analyzed and the results were similar. The mutant 407-P was also incorporated into non-sterilized soil samples, recovered, easily identified, and quantified, what enables its use in ecology of B. thuringiensis.
