title: [What are toxins to microbes? (the role of toxins in bacterial ecology)].
abstract: The author attempts to answer two questions: whether the toxins, in particular the toxins having their specificity connected with enzymatic activity, are needed for microbial cell physiology and their significance for bacteria that are not the obligate parasites for warm blooded animals. The analysis of literary data supposes the toxins to be essential cellular metabolites since many of them participate in energy acquiring. Besides that a number of toxins is shown to be relevant to microbial life and to affect the micropredators, especially the monocellular organisms feeding the microbes. In connection with the above mentioned, special attention is paid to extrachromosomal location of many toxins genes relating them to bacteriocins. The possibility is not excluded that in the future the new toxins might come to be found having the enzymatic activities.
