Toxicity and Microcystin Content of Extracts from a Planktothrix Bloom and Two Laboratory Strains

Abstract : Toxic effects and microcystin content from various extracts of aPlanktothrix agardhiibloom and two different strains ofPlanktothrix agardhii, HUB 076, and NIVA 34 were investigated. Extracts were obtained with solvents of different polarity such as hexane, dichloromethane, methanol, and water. Additionally, different pre-treatments were used to break the cells before extraction. Acute ...

1-day Hands-on Liquid-Liquid Extraction (LLE)

Liquid-Liquid Extraction (LLE) is a method for separating compounds based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic. The solvent that is enriched in solute(s) is called the extract. LLE is a ...
