Microbial communities composed of several community members may possess advantages over single species with respect to their ability to cope with environmental stress. For instance, such complex communities may be more stable with respect to their resilience to stress and maintenance of activities. Further, mixed communities may be able to more sufficiently use substrate resources or occupy different niches, thus resulting in an overall higher performance. Within this master topic, the validity of this ecological theory will be assessed for a particular example of biotechnological relevance, i.e. the decolourisation of textile dyes by fungi. The work will focus on complex fungal communities to be constructed from single strains that are available from a culture collection. Due to the demand for efficient biological treatment methods for effluents from the dyestuff industries, the decolourisation of textile dyes and fungal growth will serve as activity parameters with a bio-te
chnological significance, and hence will be assessed in corresponding laboratory experiments. Relative abundance of fungal strains will be further analysed using molecular tools. During these experiments, extreme (alkaline) pH values and high salt loads (both prevailing in certain effluents of the dyestuff industries) will be applied as environmental stressors.
