THE IDENTIFICATION AND ENUMERATION OF FRESHWATER ALGAE AND CYANOBACTERIA
IInnttrroodduuccttiioonn Micro-Algae, commonly referred to as ‘Algae’ is a term used to define ‘microscopic aquatic non stem-forming plants’. The term Phytoplankton refers to all suspended microalgae, including the group Cyanobacteria (commonly called blue-green algae). Cyanobacteria are of great significance due to their potential toxic effect on animals and humans should an ‘algae bloom’ occur. Algal populations within a water body (e.g. lakes, rivers and reservoirs), are monitored to help protect stakeholders through early detection of toxic algal blooms. This is achieved through the regular enumeration (counting) and identification of the phytoplankton genus/species. Following extensive validation and external expert technical review, ALS is pleased to offer NATA accredited enumeration and identification services for;

PPrriinncciipplleess ooff AAnnaallyyssiiss The enumeration and identification is conducted on a preserved sample, which is concentrated via Gravitational Sedimentation. 90% of the sample is then siphoned off leaving a final aliquot for analysis. The aliquot is loaded into a calibrated “Lund Cell” and viewed under phase contrast microscopy to identify and enumerate the Algae Species. The results are expressed as Cells/mL. The Biovolume phytoplankton test is conducted on an aliquot using phase contrast microscopy at 1000X magnification under oil immersion. The cell dimensions are recorded and the volume of algae is calculated with results expressed as mm³/L.
HHoollddiinngg TTiim mee aanndd PPrreesseerrvvaattiioonn Samples that cannot be received by the Laboratory within 12 hours of sampling require the Algae to be preserved with Lugol’s solution in accordance with NATA guidelines. The iodine in the Lugol’s solution preserves the cells and flagella and also facilitates sedimentation and once preserved can be submitted un-chilled. Samples submitted without ‘Lugols’ must be maintained in the dark and transported in an esky (
