Algal metabolites: chemical, biological, ecological and applied perspectives

GREAT LAKES 1]. Taste and odour (T/O) outbreaks, Lake Ontario. W.  Lake Ontario Research Consortium; SLRI; U. Calgary, U.Toronto, U.  Waterloo, ATE Inc. GOALS:  a) W. Lake Ontario: i) isolation of  Anabaena lemmermanii; Pseudanabaena spp.; ii) factors influencing in  vitro growth, morphology, odour, akinete production; iii) use of  genetics to identify these biota in field; iv) seasonal, spatial  changes in abundance iv) relationship between T/O and temperature,  downwelling; b) E. Lake Ontario, Grimsby, Saint Lawrence River:  i)  characterize biota and odour production in periphyton, mussel beds;  ii) key modifiers: flow, temperature, light, nutrients.USE:  water  industry and government  2]. Toxic Cyanobacteria in Hamilton Harbour.  NWRI (S.Watson,  M.Charlton); ATE Inc.GOALS: i) field samples, enclosures/lab assays  to assess spatial, temporal variation and relationships among light,  temperature, nutrients, algal abundance, toxin levels, mussels,  zooplankton; ii) growth, toxin production of algal isolates; iii) use  of genetics, pigments to identify and monitor key species; iv) toxin  levels in food web (fish, mussels, waterfowl). USE: local sewage- and  drinking water plant management, public, RAP.      3]. Actinomycete odour in source water. NWRI , U Calgary, OME GOALS:  assessment of: i) Actinomycetes as odour sources in periphyton and   mussel beds; ii) species-specific responses to temperature. USE:  water industry and watershed management. 4] Industrial odour. I)  Cornwall pulp mill. NWRI, SLRI; Domtar  GOALS: i) temporal changes in geosmin/MIB in active sludge related to  key factors (temp, nutrients); ii) major changes in cyanobacteria  over this period; iii) isolate major cyanobacteria and characterize  odour iv) sample other pulp mills - evaluate significance of  cyanobacteria geosmin/MIB within the industry. USE: industry Major Products: Increased understanding of the major causes and  effects of algal-derived aquatic T/O and toxins in Lake Ontario and  other surface waters, which will contribute towards an ability to  predict, treat and eventually reduce these events.
