[Phenotypic expression of a 100-pair nucleotide deletion in the regulatory region of the Bacillus subtilis riboflavin operon].

Assessment of specific activity of riboflavin synthase and the level of riboflavin accumulation in strains with a 110-nucleotide deletion in the regulatory region of the riboflavin operon showed that this deletion specified semi-constitutive expression of the operon. This was assumed to be connected with the elimination of three nucleotides from a potential transcription antiterminator.

[Analysis of the primary structure of the supplementary regulatory region of the riboflavin operon in Bacillus subtilis].

The sequencing of a 3.5 kb EcoRI-BamHI fragment located in the 236 degrees region of the Bacillus subtilis chromosome revealed a 690-bp long open reading frame, partly similar in amino acid composition to flavokinases/FAD synthases from several microorganisms. The discovered sequence can be identified with the gene ribR, an auxiliary regulatory gene of the riboflavin operon of Bacillus subtilis.

[Protection from radon emissions from a radon laboratory].

An absorbing chuck with activated coal has been suggested for absorbing radon and its daughter products' wastes from the air which are formed in the device YPP-1 in the process of preparation of radon water concentrate. Testing of such a device has shown that it is simple, reliable and efficient in functioning, thus it can be recommended to be used in radon laboratories.
