Abstract
Summary
Several particulate compounds such as Celite, glass powder, tin oxide, diamond powder, and three different cellulose products, Microcrystalline Cellulose, Solka Flok, and Cellophane Spangles, stimulated population growth in C. briggsae. Since inert diamond particles form a poor adsorbent, and since large particles did not enter the gut of the nematode, our results suggest that stimulation is not the result of nutrient adsorption or phagocytosis, but rather due to the physical presence of particles.
