Evaluation of the Number of Different Genomes on Medium and Identification of Known Genomes Using Composition Spectra Approach

The article presents the theoretical foundations of the algorithm for calculating the number of different genomes in the medium under study and of two algorithms for determining the presence of a particular (known) genome in this medium. The approach is based on the analysis of the compositional spectra of subsequently sequenced samples of the medium. The theoretical estimations required for the implementation of the algorithms are obtained.
