Bivalve Disease Culturing. The gel form contains millions of tiny pores that can adsorb and hold moisture. The Marine Invasions Lab use agarose gels for DNA analyses to identify parasitic protozoans (Perkinsus, haplosporidians, gregarines) in seawater and sediments, and in bivalve tissues collected along a north to south gradient to look at the diversity and distribution of the different parasite species. Most of the world's 'red gold' comes from Morocco. The Marine & Estuarine Ecology and Fish & Invertebrate Ecology Labs use a product called Ray's Fluid Thioglycollate Medium (RFTM), which contains about three percent agar, to culture Dermo (Perkinsus marinus).
There are synthetic agar products available for media and culturing purposes, but some are toxic to certain fungi and orchid seed species. Today, harvest limits are set at 6, 000 tons per year, with only 1, 200 tons available for foreign export outside the country. Silica gel is essentially porous sand.
