Concrete & the Challenge of Microbial Induced Corrosion

Of the more prominent challenges facing the construction industry are those related to  deterioration of material and structures by actions of microorganisms.  The process is  loosely known as Microbial Induced Corrosion (MIC), which belies an incredible range of processes occurring as a result of the growth of microorganism, principally bacteria, on our steel and concrete […]

Assessment & Control of Microbial Contamination

 A Guide to Microbial Testing:  Microbial Control vs Microbial Elimination For Additional Guidance: First Steps to Microbial Product Testing In antimicrobial systems or microbiology testing, confusion arises when a particular system is being evaluated since the acceptable concentration of microorganisms for any particular process can differ.
