Bacillus sp. strains having chitinolytic and proteolytic activity which have been isolated from tropical soils
This work was aimed at selecting native strains from the Bacillus genus having chitinolytic and proteolytic activity from soil from the tropical coast of Oaxaca, Mexico. 150 strains were isolated, 22 of which were selected as they presented chitinolytic and proteolytic activity. Such activity was assessed by the formation of a hydrolysis halo around the colony in culture media supplemented with 5% colloidal chitin and 1% skimmed milk. The LUM B001, B003, B013, B015 and B065-chitin strains presented higher quitinolytic and proteolytic activity, thereby having the potential for being evaluated in the biological control of phytopathogenic fungi. The Bacillus genus was found in cultivated and uncultivated soils; no statistical differences were found according to established crop (P.
