Microbial biodeterioration of a great many materials (including concretes, glasses, metals and their alloys, and plastics) occurs by diverse mechanisms. 

Materials of Construction MIC processes are those processes by which manufactured materials deteriorate through the presence and activities of microbes. These processes can be either direct or indirect. Microbial biodeterioration of a great many materials (including concretes, glasses, metals and their alloys, and plastics) occurs by diverse mechanisms and usually involves a complex community consisting of many different species of microbes. 

The impregnation of PF (phenol-formaldehyde) resin into wood was studied in the early part of the twentieth century. PF resin wood composites have been commercialized as Impreg and Compreg for their high mechanical strength and dimensional stability. Although the enhancement of decay resistance by PF resin treatment was also found earlier [1], it has not been applied to wood preservation techniques for the prevention of biodeterioration.

It is important to note that all microorganisms involved may occur jointly. Due to their differing physiology, various mechanisms may contribute to biodeterioration. Additionally, some cotmter-measures (e.g., antibiotics) will be ineffective for such complex microbial consortia, especially when eukaryotes and prokaryotes occur together. 

Despite the staggering diversity of microbial life on earth, biological mechanisms influencing or causing biodeterioration may be summarized in a few main categories. It should be pointed...

As already stated, MIC of metallic materials does not involve any new form of corrosion. The mechanisms involved in the biodeterioration of materials have already been given in detail. The main ways in which microorganisms may enhance the rate of corrosion of metals and/or the susceptibility to localized corrosion in an aqueous environment are given below in relation to known corrosion mechanisms (for each case some examples are also given) ...

The biodeterioration of plastics by microorganisms can occur by different mechanisms ... 

Invertebrates and insects such as crickets, slugs, and snails can consume plastics as food. Mechanical damage is caused by the gnawing activities of termites, insects and rodents [16]. Plastics susceptible to this type of biodeterioration are usually protected with insect or...
