The alteration in the chemical structure of a substance, brought about by biological action, resulting in the loss of a specific property of that substance.  2, record 1, English, - primary%20biodegradation

Record number: 1, Textual support number: 1 CONT

Primary degradation occurs when the molecule has been oxidized, or otherwise altered by bacterial action to such an extent that its characteristic properties are no longer evident or when it no longer responds to analytical procedures more or less specific for detecting the original surfactant.  3, record 1, English, - primary%20biodegradation

Record number: 1, Textual support number: 2 CONT

In relation to surfactant biodegradability, it is important to distinguish between primary and ultimate biodegradation. For example, the loss of the ester sulphate groups from surfactants such as sodium dodecyl sulphate or sodium dodecyltriethoxy sulphate would be a primary biodegradation step that would lead to an immediate loss of susfactant properties. ... For the most part, industry and water and sewage authorities have been content to ensure that new surfactant products do undergo reasonably rapid primary and ultimate biodegradation and a variety of laboratory tests have been developed specifically since the advent of synthetic surfactants.  4, record 1, English, - primary%20biodegradation

cesspool; cesspit: We haven’t been able to clearly distinguish those two terms, considered as synonyms by some authors but as different concepts by others.

L'estran constitue une transition entre le milieu marin aquatique et le milieu terrestre aérien. [...] L'estran est une zone de transition qui pouvait être conquise par des organismes terrestres comme par des organismes aquatiques. Or dans la conquête de cet espace, c'est plutôt le monde marin qui l'a emporté. À part quelques insectes, un pseudo scorpion et un mille patte, on y trouve en effet essentiellement des organismes marins. Pour exploiter cette zone, il y a deux stratégies dominantes : suivre le mouvement de l'eau et se retirer avec le jusant ou bien s'accommoder de passer une partie plus ou moins longue de son temps émergé. Les poissons ont choisi en général la première solution. Les organismes fixés, comme les algues, ou peu mobiles, comme les mollusques, ont opté pour la deuxième. Il existe aussi des stratégies intermédiaires comme la survie dans des flaques suspendues.  3, record 6, French, - organismes%20fix%C3%A9s
