Attention is directed at the importance of cyclic processes in nature for the functioning of the environment. In this light, the biodegradability of materials and chemicals is of great importance. In particular, persistence of chemicals, like DDT, is a phenomenon that deserves serious study. The possible causes of persistence are discussed,...

Different sources of C and N in mildew test media are compared. It is found that filterpaper strips may be advantageously replaced by cellulose powder. Carboxymethylcellulose is less favourable as a substitute and it is confirmed that the addition of saccharose adversely influences cellulolytic breakdown. More complex carbon sources do not seem...

A total of 164 fatty nitrogen compounds, consisting of quaternary ammonium compounds, alkylamines, N-alkyl-1, 3-propylene diamines, substituted amino hydroxystearonitriles, substituted amino hydroxystearyl amines, and nitrogen-containing surfactants, were screened for bacteriostatic, fungistatic, and algistatic activity. The most active...

The biodeterioration of materials is considered from the point of view of a biologist. As such it is part of hylobiology which deals with the biotic phenomena associated with materials. It is discussed that phenomena of biodeterioration have some resemblance with phenomena of human and plant-disease. Also in the methodological approach they have...

Research on biodeterioration of materials has been reported previously in "TNO-Nieuws" (ibid. 13, 398-405 (1958). Meanwhile this work has received considerable impetus from the formation of an international Group of Experts under the aegis of the Organization for Economic Co-operation and Development (OECD), Paris. For the first time a forum of...

A short literature survey on chemical sterilization with β-propiolactone is given. The auto-inactivatio 1 of this compound in aqueous solution appears to be one of its main advantages. Time-kill studies have been carried out with bacterial cells and spores, and with fungal spores. The compatibility of BPL with textiles and plastics was also...

Existing test methods for the moth‐proofness of wool were compared in inter‐laboratory experiments and found to be lacking in accuracy and agreement between laboratories. Several factors influencing the usefulness of such a test method were investigated, and it was found that a considerable gain in accuracy could be reached if weight loss due to...
