Abstract
The present invention relates to the use of compositions for isolating and/or stabilising nucleic acids in or from microorganisms—such as prokaryotes, fungi, protozoa or algae. The composition contains, as an essential ingredient, a cationic compound of general formula Y+R1R2R3R4X− wherein Y may denote nitrogen or phosphorus, R1, R2, R3 and R4 independently of one another may denote an unbranched or branched C1-C20-alkyl group and/or a C6-C20-aryl group as well as a C6-C26-aralkyl group, and X− may denote an anion of an inorganic or organic, mono- or polybasic acid.
