Protease and Amylase in the digestive tract of Barbus paludinosus by ALAN COCKSON & DAVID BOURN * ABSTRACT 1 .
Protease and amylase activity in the digestive system of Barbus paludinosus PETERS (Pisces, Cyprinidae) has been investigated .
2 . Chromatographic analysis showed seven amino acids to be present in both the anterior and posterior intestine . Only leucine, phenylalanine, valine, glycine and aspartic acid were positively identified .
4 . The pH of the intestinal fluid was found to be 5 .8 and 7 .8 for the fore and hind gut respectively, This correlates well with the enzyme pH optima found in in vitro experiments .
6 . Correlation between the digestive enzymes and the fishes diet is briefly discussed .

Wombats consume grasses and sedges which are often highly fibrous. The morphology of the digestive tract and the sequence of digestion were studied in two species of wombats from contrasting habitats: Vombatus ursinus from mesic habitats and Lasiorhinus latifrons from xeric regions. Studies were per
Hydroxycinnamic acids are consumed as water-soluble conjugates and in larger amounts bound to plant cell walls. Bound acids are primarily released by microbial action in the modiΓΌed forestomach of ruminants and the hindgut of non-ruminant species, including humans. In the rumen, rapid hydrogenation
