Degradation of microcystin-LR by aquatic bacteria.
… are cyclic heptapeptide toxins produced by cyanobacteria. They are potentially a threat to human and domestic animals so are of worldwide interest. Microcystin-LR is stable in various environmental conditions. It is important to know the factors affecting microcystin degradation which can be …

Decomposition and Production of Dissolved Organic Matter by Aquatic Bacteria
Aquatic ecosystems transport large amounts of organic matter from the landscape to the oceans. Along this pathway, heterotrophic bacteria rapidly cycle these compounds by acting as both degraders and producers of organic compounds. Understanding the ultimate fate of the organic matter and …

Factors influencing the abundance, community composition and activity states of bacterioplankton from the tidal freshwater James River
Aquatic bacteria respond to changing environmental conditions through a variety of mechanisms including changes in abundance, shifts in community composition and variable activity states. In the tidal-freshwater James River, variation in bacterial abundance was linked to nutrient availability and …

DEVELOPMENT OF A RAPID DIAGNOSTIC ASSAY FOR THE COLORIMETRIC DETECTION OF LEGIONELLA BACTERIA USING LOOP MEDIATED ISOTHERMAL AMPLIFICATION
<p><em>Legionella </em>are aquatic bacteria capable of inhabiting man-made water systems. Inhaling water droplets carrying <em>Legionella </em>can cause Legionnaires’ disease, a rapidly progressing pneumonia. From 2000-2016 the number of Legionnaires’ cases increased 5-fold. Detecting …

Winter Limnological Conditions in a PRAIRIE Pothole and the Application of Molecular Oxygen
… to 14.1 mg/L) decreased throughout the winter. Aquatic bacteria and fungi comprised from 87.0% to 93.7% by number of the total cells identified (phytoplankton, bacteria, and fungi) in the lake water under ice. Dissolved oxygen declined to anoxic conditions after 19 January, 1978, and hydrogen …

Effects of Freshwater Salinization and Associated Base Cations on Bacterial Ecology and Water Quality
… environments (~1,500 – 60,000 µS cm-1) influence aquatic bacteria. Less is known about the effects of freshwater salt concentrations (≤ 1,500 µS cm-1) on bacterial ecology, despite the pervasiveness of freshwater salinization. Bacteria perform many fundamental ecosystem processes (e.g. …
