摘要：

1. The effect of sodium chloride and sulphate concentrations on the rate of sulphation was evaluated in four developmental stages of the brine shrimp Artemia franciscana, a crustacean inhabiting extreme hypersaline environments. 2. An increase of 4-5-fold in the sulphation rate of macromolecules was observed at 0.6-0.8 M NaCl compared to 0.4 or 1.0 M NaCl. 3. Increase of sulphate concentration in the artificial sea water produced an increment in total sulphation of at least 30-fold. 4. The rate of sulphation decreased during development of the brine shrimp. It is higher at early nauplii stage compared with pre- or adult organisms. 5. Several sulphated macromolecules were observed after fractionation of sulphated material obtained from organisms under different stages of development. The predominant form correspond to a proteoglycan (PG) of 270-400 kDa.
