it is established that the use of dna-dependent rna-polymerases of mollicutes in the molecular-biological and gene-engineering works aimed to obtain a sufficient amount of the transcription products may promote a 1.5-2-fold increase of the yield by introducing such substances as glycerol , dimethylsulphoxide and spermidine ( optimal concentrations : 10-12 vol .
