“…However, in contrast to many other polymer-degrading organisms, the strains that are able to deal with PVA are not easily isolated from biotopes that have no PVA exposition history. Many examples are available in the literature that describe successful isolation of those species from PVA polluted environments [55]. This general finding for PVA degraders might be explained from an evolutionary point of view.…”

This chapter deals with the biodegradability of vinyl ester-based polymers with a special emphasis on poly(vinyl acetate) and poly(vinyl alcohol). A proper discussion of the importance of the biodegradability of a certain polymer class cannot be made without understanding the impact that polymer class has on the environment. Therefore, apart from discussing the actual biodegradation mechanisms, other issues will be addressed. These include, but are not limited to, how long the class of vinyl ester-based polymers has been known and produced on an industrial scale, what quantities are produced and released into the environment each year, and what applications are addressed with this polymer class. We will also look at the general physical and chemical properties of this polymer class and how these properties can influence biodegradability. After a discussion of what "biodegradability" actually means -and what not -the mechanisms for the biodegradation of poly(vinyl ester)s will be discussed in more detail and a summary given of the biological systems able to process poly(vinyl ester)s.

“…Bacteria are thought to be the major microbial domain responsible for the biodegradation process and bacteria belonging to the Bacillus species are more predominant in the thermophilic stage of composting[51]. A number of studies have been conducted to identify the microbial consortia present in the compost environment[52][53][54], and some have reported the isolation and identification of several species capable of the biodegradation of PLA[55][56][57][58][59][60][61][62][63], and other polymers[45,[64][65][66][67][68][69][70][71]. The isolation of these bacteria has been done using selective enrichment and clear zone formation, in which the specific polymer was provided as the sole source of carbon.…”

The development of novel biodegradable polymers as a way to create sustainable materials has required the development of methodologies to evaluate and understand their biodegradation. In this work, we first provide a critical summary of selected biodegradation tests performed in the last fifteen years for a number of biodegradable materials, providing relevant information about the materials tested, characteristics of the compost used and the method for testing. Then, we report a comparative analysis of the results obtained from eight different biodegradation tests performed in simulated composting conditions by analysis of evolved CO 2 and carried out in an in-house built direct measurement respirometer. The materials evaluated for biodegradation were cellulose, starch, glycerol, polyethylene, and poly(lactic acid). Our results along with the information provided in the literature allowed us to identify that one of the main issues of biodegradation testing is the low reproducibility due to the number of variables involved in the biodegradation process. It is difficult to provide fair comparisons of samples that are not within the same test. Therefore, we provide a critical overview of the different factors affecting the biodegradability, biodegradation rate, and biodegradation mechanisms of polymeric materials. Furthermore, we share the experiences and insights gained during the performance of the different biodegradation tests, and identify areas of opportunity for improving biodegradation testing through evolved CO 2. This information should create a common knowledge platform for people interested in studying the biodegradation of materials.
