An exopolysaccharide depolymerase was isolated from a mucoid strain of Pseudomonas aeruginosa of cystic fibrosis origin. Purified preparations of the depolymerase showed maximum activity against the unacetylated polymannuronic acid exopolysaccharide from the same strain and little activity against commercially prepared alginic acid. The evidence suggests that the enzyme is either periplasmic in...

The effects of octadecylamide alginic acid (amidated alginate) and tetrahydrolipstatin on serum hepatic cholesterol, the faecal output fat sterols, were investigated in rats. Amidated alginate is a sorbent lipids, an inhibitor pancreatic lipase. Rats fed diets containing cholesterol palm at 10 70 g/kg, respectively. Palm was provided by coconut meal. 40 g/kg diet significantly decreased total l...
