Wilhelm Boland Institut für Organische Chemie und Biochemie, Universität Bonn, D-53121 Bonn. Bundesrepublik Deutschland Z. Naturforsch. 49c, 601-606 (1994); received March 7/May 17, 1994 Laminaria, Phaeophyceae, Pheromone Receptor Specificity, Structure-Activity Relationship The pheromone receptor specificity and threshold concentrations have been determined for spermatozoid chemotaxis in Laminaria digitata in structure-activity studies. The results are in agreement with the current concept on the pheromone receptor interaction in brown algae, which is based on mutually-induced dipole-dipole interaction, dispersion forces and hydrophobic forces. Comparison with the receptor specificity in pheromone-induced sperma tozoid release in the same species indicates that different pheromone receptors are involved in these two functions.

Interactive effects of UV radiation and temperature on microstages of Laminariales (Phaeophyceae) from the Arctic and North Sea
Spores and gametophytes are considered to be those life-history stages of kelps most susceptible to environmental perturbations and, in particular, to temperature and UV radiation. Microstages of Arctic (Saccharina latissima, Laminaria digitata, Alaria esculenta from Spitsbergen) and temperate kelp species (S. latissima, L. digitata, L. hyperborea from the North Sea) were exposed in 2-factorial...

The influence of oscillatory versus unidirectional flow on the growth and nitrate-uptake rates of juvenile kelp, Laminaria digitata, was determined seasonally in experimental treatments that simulated as closely as possible natural environmental conditions. In winter, regardless of flow condition (oscillatory and unidirectional) or water velocity, no influence of water motion was observed on th...
متن کاملPreliminary Canopy Removal Experiments in Algal Dominated Communities Low on the Shore and in the Shallow Subtidal on the Isle of Man
The algal dominated communities immediately above and below the low-water spring level on a moderately exposed Manx shore were investigated by canopy removal experiments. Fucus serratus, Laminaria digitata and L. hyperborea were removed. Competition was shown to be important in determining the zonation of L. digitata and the distribution along the wave exposure gradient of other species such as...
متن کاملCharacterization of mannuronan C-5-epimerase genes from the brown alga Laminaria digitata.
Alginate is an industrially important polysaccharide obtained commercially by harvesting brown algae. The final step in alginate biosynthesis, the epimerization of beta-1,4-d-mannuronic acid to alpha-1,4-l-guluronic acid, a structural change that controls the physicochemical properties of the alginate, is catalyzed by the enzyme mannuronan C-5-epimerase. Six different cDNAs with homology to bac...
متن کاملKinetics modeling of alginate alkaline extraction from Laminaria digitata.
Alginates being depolymerized during their alkaline extraction, reducing extraction time could help producing higher rheological quality alginates. The purpose of the present work is to study fresh Laminaria digitata destructuration during alkaline extraction and its link to extraction kinetics. Both alginate extraction yield and mean diameter of algae particles were followed for different valu...
