R. Landen et al., DISTRIBUTION OF BACILLUS-THURINGIENSIS STRAINS IN SOUTHERN SWEDEN, World journal of microbiology & biotechnology, 10(1), 1994, pp. 45-50
Bacillus thuringiensis strains were found to be naturally present in t
he soils of southern Sweden, being isolated from nine out of 12 sites
examined. Forest soil samples were more rich in B. thuringiensis strai
ns than soil samples collected from cultivated areas. A wide diversity
of B. thuringiensis strains, representing different biochemical group
s, was isolated; samples from Aspo and Fogdo regions showed the highes
t degree of diversity.
