Abstract |
A synthetic culture medium was developed for the laboratory culture of Cladophora glomerata from the Great Lakes. Recognition that Cladophora requires vitamins B1 and B12 was a key feature in the successful culture of this alga. Systematic modifications of the initial culture solution resulted in an optimum culture medium in which C. glomerata routinely produced 500 mg oven-dry algae in a 21-day period. The quantitative requirements of C. glomerata for essential inorganic nutrients were expressed primarily as critical cell concentrations, that is minimum cell concentrations which permit maximum yield. C. glomerata has relatively low critical N and P concentrations (1.1% and 0.06%, respectively) but very high B (110 ppm) and S (0.15%) critical concentrations. Ortho- , pyro-, meta, and tripoly-P can be utilized in C. glomerata growth as can NH4 and NO3-N. Phosphite-P is relatively unavailable. Nutrient supplies and limiting nutrients for Cladophora sp. growth in the Great Lakes were evaluated by two bioassays, primarily plant analysis and to some extent the Fitzgerald tests. Plant analysis assays for P showed that Cladophora P concentrations correlated closely with the recognized pollution of areas sampled. |
