Abstract

Eudiaptomus gracilis is the most abundant member of the zooplankton, plays a key role in the food web of Lake Balaton (Hungary). In the present study the composition of bacterial communities of this copepod was investigated based on cultivation and molecular cloning. The cultivated bacterial strains from the gut homogenate samples of Eudiaptomus gracilis belonged to four different clades: Firmicutes, Actinobacteria, Bacteriodetes and Proteobacteria. Clone library showed high species diversity, Firmicutes, Actinobacteria, Proteobacteria, representatives of Deinococcus‐Thermus lineage and Cyanobacteria were detected. The isolated strains were very effective in degradation of different biopolymers. Many of the detected bacteria are known as opportunistic human or fish pathogens (Pseudomonas spp., Aeromonas spp., Chryseobacterium sp. and Staphylococcus sp.). (© 2012 WILEY‐VCH Verlag GmbH & Co.

Copper-sensitive bacteria were isolated from a tropical river water sample and used to develop a simple, inexpensive bioassay for the determination of copper bioavailability in freshwaters. The 48-h bioassay, which has an EC50 for inorganic copper of 7.1 g / L, involved addition of copper-sensitive

Gut contents have long been recognized as a potentially important source of bias in studies concerned with estimating contaminant body burdens in benthic macroinvertebrates. In this study, we show that gut-associated, inorganic material may also lead to significant overestimates of weight in Chirono
