This paper summarizes the study and analysis of numerous published sources, the results of experimental work to identify the species composition of microorganisms dispersed rocks, the nature and extent of their participation in corrosion process of construction of engineering structures. Experimentally established species composition of microflora of dispersed rocks the Rostov-on-Don city, lists the most active species capable of damaging protective coatings and metal. Are briefly characterized some of the mechanisms of interaction of the products of microbial activity with building materials that lead to corrosion. Identified species has the ability to destroy the materials containing organic derivatives. Indicated lithological varieties of dispersed rocks within which biocorrosion can proceed more intensively.

Keywords: corrosion, micro-organisms, disperse rocks, engineering constructions, metal structures, bacteria, actinomycetes, micromycetes.
