https://doi.org/10.1007/978-3-662-33775-2About 100 growth curves of . in batch cultures on different growth media are analysed. In many cases after a retardation phase, a second exponential growth phase appears. The accuracy of measurements of the different growth phases as effected by the growth medium is discussed.

International Conference on Environmental Bioassay Techniques and their ApplicationA short overview is given of the primary objectives of environmental research and management and of the importance of bioassay to these objectives. Current deficiencies in the availability of quantifiable bioassays and in the formulation of research needs and priorities are highlighted.

Zielvereinbarung und variable Vergütungbe the extent to which an ecosystem is being or has been polluted, and to predict the ecological impact of agents before release. Problems associated with the choice and implementation of bioassays in both these modes are discussed. A major general conclusion is that the experimental method should play a prominent part in addressing the problems.

The use of environmental assays for impact assessmentanalyses for toxic chemicals and the relevance of bioassays for predicting risk to ecosystems. Research is urgently needed to find better ways to solve these problems, particularly with respect to chronic exposures.

Zielvereinbarung und variable Vergütungconclusion is that some bioassays have more severe problems than others, but a concern with all of them is that responses observed in particular systems may not be relevant in general. The possibility of developing a general theoretical infrastructure for bioassays that addresses this problem is considered.
