The secretion of chitinases in the digestive tract of most fish species indicate that fishes must play an important role in the recycling of chitin carbon and nitrogen. Some fish species are equipped with B-1,3 glucanases (or laminarinases) generally secreted by their own intestinal mucosa, and are thus able to take part in the biodegradation of B-1,3 glucans such as laminarin, leucosin, paramylon, etc. On the contrary, fishes seem to be entirely unable to digest cellulose and thus can hardly play any role in the biogeochemical cycling of this important organic compound.

Despite the appearances, the Thaliacean fauna of the Red Sea (as well as the fauna of the Persian Gulf) is of an indo-pacific origin. Only a few worldwide scattered species are common with the eastern Mediterranean. Owing to the severe environmental conditions (heat and mostly high salinity) and the presence of sills, the fauna of the Red Sea and especially those of the Gulf of Suez and of the Persian Gulf, are poorer than the fauna of the Indian Ocean proper and of the Gulf of Aden.

The structure and the composition of the cuticule of the Tardigrada Macrobiotus sp. and Milnesium tardigradum are studied. The cuticle is always made of two distinct layers extending to the stomodeum. By the two species, the cuticle contents, besides chitin, acid mucopolysaccharides and protids. These facts are arguments to bring nearer Tardigrades and Arthropods. [less ▲]

The distribution of chitinase secretion has been studied in four species of Rodents. The biosynthesis of this enzymes is only performed by the gastric mucosa ; the pancreas seems to be unable to secrete chitinase, as far as Rodents are concerned. In the cases of the Rat and the Mouse, the individual variability may be reduced to a minimum by using animals of the same age, sex and size, sacrificed at the same moment with respect to the last meal. Among the species so far studied, the Guinea-pig is the only one which does not secrete a gastric chitinase. The Hamster secretes only small amounts of chitinase, while Rats and Mice, which are omnivorous, exhibit an important gastric chitinase secretion. In the latter animals, the chitinase contents of the gastric mucosa are as high as in some Reptiles or insectivorous Birds. These observations confirm the existence of a correlation between the ability of a given species to synthetize chitinase and the feeding habits of this species. [less ▲]

The distribution and localisation of chitinolytic enzymes (chitinase and chitobiase) have been studied in five different species of Birds and nine species of Mammals. Chitobiase has been found in aqueous extracts of many glandular tissues, but its activity is low everywhere. No chitobiase has been found in kidneys and muscles. The gizzard's contents and intestinal chyme of the Sparrow, of the Blackbird, of Liothrix lutea and of the Cock are able to hydrolyse "native" chitin. The chitinase is secreted by the mucosa of the glandular stomach. Chitinase secretion seems to be lacking in the Pigeon. Among Mammals, a secretion of gastric chitinase has been observed in a Bat (Rhinolophus ferrum-equinum), in two Insectivors, the Mole and of the Pig seems also to be able to synthesize this enzyme. The other Mammals so far studied (Rabbit, Cat, Sheep, Choloepus and Man) do not appear to secrete chitinase. These results suggest the existence of a relation between the dietary habits of Vertebrates and the secretion of chitinase by some of their glandular tissues. The gastric chitinase of the Hedgehog has an optimal pH in the range of 4.7 to 5.0, which does not differ from that of other well-known chitinases extracted from Streptomycetes, Snails or Insects. The difference between these enzymes and the gastric chitinase lies in the fact that the latter is much less inhibited in acid conditions than in neutral or alkaline ones. The gastric chitinase seems in fact to be active at the pH conditions of the gastric chymes. [less ▲]
