Two strains of bacilli are shown to produce a relatively large amount of extracellular low-molecular weight alkaline RNases, which suggests that the protein sequences of the RNases of Bacillus species have been conserved in the course of evolution.
[Cloning of the gene for extracellular Bacillus circulans RNAase].
The gene for extracellular low molecular weight ribonuclease of Bacillus circulans BCF 247 was cloned and the smallest DNA fragment which enclosed a functional ribonUClease gene in E. coli was determined to be 0.6 kb in length.
[Bacteriocinogenic plasmids of Bacillus thuringiensis].
The comparative analysis of the plasmid content of original and mutant strains revealed that the appearance of Ospo and Thc- phenotypes correlated with the loss of certain plasmids.

The majority of the Inc+ recombinant plasmids showed asymmetric expression of incompatibility, predominantly eliminating the resident IncP plasmid.

As it was shown by comparative analysis the frequency of transfer and stability of the maintainance of plasmid pAM beta 1 in Bacilli were not connected, the molecular weight and restriction pattern of pam beta 1 DNA isolated from Bacilliwere the same as those of pAMbeta 1 DNA from Streptococcal donor strain.
[The role of Bacillus thuringiensis in natural biocenoses].
It has been concluded that there is no strict confinement of B. thuringiensis strains of the particular serotypes to certain habitat and that the bacteriocinogenicity is of great importance in the intraspecies competition and stability of strains in nature.
