TL;DR
Bacteria-free suspensions of larvae of Strongylocentrotus purpuratus (Stimpson) were prepared without the use of antibiotics and removal of neutral amino acids occurred at rates adequate to contribute to the carbon and nitrogen balance of the larvae at ecologically relevant substrate concentrations.
Abstract
Bacteria-free suspensions of larvae of Strongylocentrotus purpuratus (Stimpson) were prepared without the use of antibiotics. Net rates of removal of 18 amino acids, each supplied at 125 nanomoles per liter, and the appearance of ammonia were measured by high-performance liquid chromatography. Taurine and acidic and basic amino acids were not taken up. Removal of neutral amino acids from the medium occurred at rates adequate to contribute to the carbon and nitrogen balance of the larvae at ecologically relevant substrate concentrations.

Polycarbonate Nuclepore filters are better than cellulose filters for the direct counting of bacteria because they have uniform pore size and a flat surface that retains all of the bacteria on top of the filter.

The uptake of dissolved organic matter by bacteria, phytoplankton and invertebrates is discussed referring to the literature and it appears to be primarily a bacterial process.

It is concluded that uptake of amino acids occurs sufficiently generally and at such rates that it should be included in any analysis of the pathways whereby material is acquired from the environment by marine organisms.

High-performance liquid chromatography provides direct evidence for substantial removal of naturally occurring specific free amino acids during a single passage of water through the mantle cavity of mussels.

Kinetic studies showed that both species have a Kt value of 3-4 µM, indicating that bivalve larvae have amino acid transport mechanisms that function efficiently in natural sea water, which is similar to those reported for adult bivalves.

Experimental evidence is presented to show that the kinetics of uptake by larvae allow them to compete with bacteria for dissolved organic material in sea water, and in larvae, supplementary sources of energy may be more important than in adults.

91 Citations1969R. E. Johannes, S. J. Coward +1 more
Removal of radioactively labelled organic compounds from solution by marine invertebrates does not constitute proof of net uptake of these compounds, and observations on the uptake and release of total dissolved free amino acids by the marine turbellarian, Bdelloura candida, indicate the net flux is out of the animal.

75 Citations1966J. M. Mitchison, Joe Cummins
The rate of uptake of valine and Hcytidine into the metabolic pool of early embryos of the sea urchin Paracentrotus lividus was measured by giving 5-min pulses of these precursors, and it was suggested that the transport mechanisms are mediated by specific carrier molecules at the cell surface.
Developmental BiologyPatterns and rates of protein synthesis in sea urchin embryos
65 Citations1970Barry J. Fry, Paul R. Gross
The metaphase depression in uptake and incorporation observed in sea urchin embryos is quite different from the metaphase arrest of protein synthesis in HeLa cells, and control of translation by factors released from nuclei at metaphase thus does not operate in the cleaving embryos.

The studies show that M. edulis is capable of a net uptake of dissolved amino acid from the very low concentrations characteristic of seawater, and the rates of amino acid uptake may contribute significantly to the animals' energy requirements.

Tests were made of the uptake and incorporation into protein of a neutral, an acidic and a basic amino acid by unfertilized and fertilized eggs of Lytechinus pictus and showed competition occurring principally among amino acids belonging to the same group.

In this type of test regime, free chlorine was three to fourteen-fold more toxic (depending on the species) than monochloramine; water quality criteria for the protection of fish should, in the future, take this differential toxicity into consideration.

There is poor correlation between the cell volume and the oxygen consumption in individual eggs, both of which vary considerably and the cycling, if present, is strongly damped and often disappears after two to three divisions.

The data obtained do not provide evidence that, in A. rubens, epidermal amino-acid uptake significantly contributes to metabolic energy demands, and it is revealed that uptake of dissolved amino acids is primarily a bacterial process.
