Evaluation of the antimicrobial efficacy of industrial substrata

In this chapter we provide different methodologies to assess the antimicrobial activity of various substrates for industrial application. The capacity of microorganisms to colonize or remain viable on a variety of media: paintings, all kinds of plastic, wood, stone, concrete, etc., can produced a deterioration and even the possible role of these substrates as infection vectors processes in humans and animals. In this sense and based on Standards of International control we have developed a simple and reliable method to verify, if the ability of individual carriers treated with natural products with inhibitory capacity of microorganisms to prevent, delay and/or minimize its biodeterioration.
