Interactions between different phytoplankton taxa and heterotrophic bacterial communities within aquatic environments can differentially support growth of various heterotrophic bacterial species. In this study, phytoplankton diversity was studied usi

Grazing is a major regulating factor in cyanobacterial population dynamics and, subsequently, considerable effort has been spent on investigating the effects of cyanotoxins on major metazoan grazers. However, protozoan grazers such as free-living amo

Climate change may cause increased microbial growth in water sources and more knowledge is required on how this may affect the hygienic water quality, i.e., whether increased occurrence of cyanobacteria and algae may stimulate the growth rate of oppo

This study aims to check if the protein content of a cyanobacterial culture is a reliable biomass parameter for cyanobacteria in laboratory experiments, and therefore can be proposed as a standard biomass parameter in culture work to facilitate compa

Nonribosomal oligopeptides were used as qualitative and quantitative markers to test whether populations of the toxic freshwater cyanobacterium Planktothrix comprise subpopulations with dissimilar ecological traits. A field program was conducted in L

Several methods for typing of Legionella pneumophila exist, one of which is an 8-locus variable-number of tandem repeats analysis (MLVA). This method is based on separating and sizing amplified VNTR PCR products by agarose gel electrophoresis. In the

Cyanobacteria produce a large number of bioactive oligopeptides with yet unknown functions. Here the effect of environmental factors on the production of two anabaenopeptins and a microviridin by Planktothrix agardhii was investigated. The results we

The comparability of current microcystin analysis methods has been evaluated in an international intercomparison exercise. The focus was on the analysis of microcystins by high-performance liquid chromatography coupled with ultraviolet or photodiode-

The correlation between the ratio of microcystin to protein and the energy state of Microcystis aeruginosa NIVA-CYA 228/1 (Chroococcales, Cyanophyta) was examined at three levels of phosphorus and ...
