Opis (eng)

Abstract Microbiologically influenced corrosion was recognized in the mid-20th century, but the study of corrosion influenced by microorganisms (prokaryotes) is relatively new compared to other research. Microbiologically induced corrosion (MIC) can manifest in diverse environments, extending beyond aqueous conditions to thrive even in humid atmospheres. Biofouling pertains to the adhering of biological matter (including bacteria, algae, and various microorganisms) on surfaces submerged in water. In groundwater settings, biofouling manifests when these organisms attach to well screens, pipes, and other infrastructure components. This buildup can restrict water flow, reduce well efficiency, and deteriorate water quality, affecting overall groundwater utilization. By simultaneously applying a system of six types of bioactivity reaction tests (BART biotests), the biochemical diversity and estimated population size of ecological groups of bacteria participating in the transformation of organic matter and redox-sensitive species were determined. These bacteria predominantly form biofilms at the water-matrix interface, water-metal interfaces, and other surfaces. The goal was to comprehensively assess the microbiological status of groundwater and detect the biochemical activity of bacteria primarily posing risks for corrosion and biofouling processes on hydraulic structures, which could also pose risks to public health. Conducted research indicated the existence of potential for possible intensive and highly aggressive biofouling processes. The forecasted risk was in the range of high risks for the development of corrosion processes.
