Cyanobacteria attack rocks: control and preventive strategies to avoid damage
caused by cyanobacteria and associated microorganisms
in Roman hypogean monuments
OBJECTIVES
•to characterise the geological, geo and hydrochemical, and
physical environment of rocks unaffected or colonised by
cyanobacterial communities inside Roman hypogea, and to
evaluate possible preferences of cyanobacteria and associated
microorganisms for specific lithologies;
•to describe the architecture and functioning of biofilms built by
cyanobacteria and associated microorganisms on different types
of lithic surfaces;
•to ascertain the most critical physical, chemical and biological
factors that control colonisation of rock surfaces;
•to assess and quantify the damage caused by cyanobacterial
biofilms to different types of surface;
•to develop new physical methods to control and prevent biofilm
growth using wavelengths in the visible part of the light spectrum
that are, at best, poorly used by photosynthesis;
•to identify siderophores and cell-to-cell signalling biomolecules
and experimentally to test their potential to interfere with biofilm
development;
SAMPLING SITES
•to develop an innovative monitoring method using a
multiparametric microsensor device for the measurement of
biogeochemical parameters on endangered rock surfaces;
CATACOMBS OF St. CALLISTUS (Rome, Italy)
CATACOMBS OF DOMITILLA (Rome, Italy)
CAVES OF BATS (Zuheros, Spain)
•to test the response and expectation of citizens to the innovative
strategies proposed.
