NELSON MANDELA UNIVERSITY’S CENTER FOR COASTAL AND MARINE RESEARCH ACQUIRES LATEST CHLOROPHYLL-MEASURING TECHNOLOGY

18 December 2017

NMU’s Center for Coastal and Marine Research have added the bbe Moldaenke PhycoProbe to their armoury of bbe chlorophyll measuring instrumentation.  The just-released PhycoProbe adds the ability to measure unbound phycocyanin, in addition to Total Chlorophyll and that from the individual groups of cyanobacteria, green algae, diatoms and cryptophytes.  The ability to measure unbound phycocyanin provides a proxy indication of cell leakage and the possible release of algal toxins into the aquatic environment.  This technology is now also incorporated in other bbe instruments such as the PhycoSens.

The bbe FluoroProbe (and more recently, the bbe BenthoTorch) has been an integral part of Professor Renzo Perissinotto’s research team for the past decade and a half.  Recent projects within Prof. Perissinotto’s Shallow Water Ecosystem (SWE) SARChI Chair have focussed on three sectors, in addition to many other subsidiary projects: (1) seasonal long-term monitoring of the dynamics of Lake St. Lucia, the largest estuarine lake system in southern Africa, (2) biological community responses and baseline monitoring of proposed hydraulic fracturing of shale gas sites in the Karoo, and (3) ecosystem drivers of living peritidal stromatolites growing along the South African coastline.  In all of these ecosystems the data from the bbe Moldaenke units have provided valuable insight into ecological dynamics.
