Clam spat Venerupis pullastra were fed for 4 wk on &ets of 2 species of microalgae supplied singly or mixed. Microalgae were Isochrysis galbana and Tetraselmis suecica, species normally used in bivalve hatcheries. Observed growth responses were high for mixed and I. galbana diets and intermediate for the T suecica diet. A slightly higher growth rate was obtained with the mixed diet than with th...

This paper describes the ecotoxicological evaluation of five organic contaminants frequently detected in marine sediments (tributyltin, triphenyltin, benzo[a]pyrene, fluoranthene, and PCB 153) using three marine species (Vibrio fischeri, Tetraselmis suecica, and Tisbe battagliai). The sensitivity of each species varied for all compounds. The triorganotins were consistently the most toxic to all...

Photosynthetic unicellular organisms are considered as promising alternative protein sources. The aim of this study is to understand the extent to which these green sources differ with respect to their gross composition and how these differences affect the final protein isolate. Using mild isolation techniques, proteins were extracted and isolated from four different unicellular sources (Arthro...

A remarkable example of biological engineering is the capability of some marine animals to take advantage of photosynthesis by hosting symbiotic algae. This capacity, referred to as photosymbiosis, is based on structural and functional complexes that involve two distantly unrelated organisms. These stable photosymbiotic associations between metazoans and photosynthetic protists play fundamental...

The intracellular localization of calcium during contraction of striated flagellar roots of the green alga Tetraselmis subcordiformis was investigated using calcium pyroantimonate and calcium oxalate cytochemistry and energy-dispersive X-ray microanalysis. Vesicles (0.25 - 0.50 microns diameter) located in the anterior-most region of the cell are calcium-sequestering organelles. These vesicles ...
