The effectiveness of a computer-controlled cage-culture turbidostat (CCT) as an algal test was evaluated in comparison with three widely used aquatic toxicity test methods for the toxicity assessment of industrial effluents. Effluent samples were col

To investigate the effect of bacterial diagenesis on the distributions of algal lipids, the marine haptophyte Emiliania huxleyi was incubated with estuarine sediment slurries under defined conditions (oxic, sulfate reducing and methanogenic). Rapid i

Effects of cell size and/or specific growth rate were studied in 2 species of marine diatom, the large-celled Ditylum brightwellii and the smaller Chaetoceros calcitrans. Cells were grown as lightlimlted continuous cultures to produce a wide range of

The transformations undergone by chlorophyll a under anoxic conditions have been simulated by using the widespread marine prymnesiophyte Emiliania huxleyi as a substrate for a mixed bacterial community by incubation in a sediment slurry under sulphat

The major alkenes of the haptophytes Isochrysis galbana (strain CCAP 927/14) and Emiliania huxleyi (strains CCAP 920/2 and VAN 556) have been identified by nuclear magnetic resonance spectroscopy and by mass spectrometric analysis of their dimethyl d

Nannochloropsis oculata (strain CCAP 849/1) was sampled at least every 12 h over a 26-d period of batch culture growth in a 12 h/12 h light/dark illumination cycle. Exponential cell-specific growth rate was 0.5 d−1. Cell division occurred during th

Data are given on the changes in cellulose, carbon, sulphide, and redox levels in the sediments of Loch Eil, Scotland, during 1976. Comparisons are made between sediment rates and average monthly inputs of pulp fibre and the effect of sedimentary mat

SUMMARY: Urease or ATP: urea amidolyase activity was detected in extracts of unicellular algae (representing two phyla and five classes) grown with urea as sole source of nitrogen. All the algae examined that are unequivocally classified as Chloro-ph
