Cellulose digestion in insects

Minireview Cellulose Digestion in Insects

I. Cellulose digestion hns been demonstrated in the Thysanura (Lepismatidae), Orthoptera (Cryptocercidae, Blattidae). Isoptera (Mastotermitidae. Kalotermitidae. Hodotermitidae, Rhinotermitdae. Termitidae). Coleoptera (Buprestidae. Anobiidae. Scarabaeidae, Cerambycidae), and Hymenoptera (Siricidne). 2. In all but the scarab beetles. cellulose digestion is brought about by a complex of three type...

The digestion of cellulose by sheep; the extent of cellulose digestion at successive levels of the alimentary tract.

Nutritional interdependence among rumen bacteria during cellulose digestion in vitro.

A study has been made of the promoting effect of starch on cellulose digestion by mixed rumen bacteria in a cellulose-urea medium. Starch supplementation of the medium promoted the growth of bacteria that required neither amino acids (AA) nor branched-chain fatty acids (BrFA). The growth of these bacteria was followed by the growth of AA-dependent bacteria, AA- or BrFA-dependent bacteria, BrFA-...

Cellulose digestion and phenol oxidation in coastal isopods (Crustacea: Isopoda)

In order to test three hypotheses on digestive constraints that may have affected the colonization of land by isopods, two marine isopods and one semi-terrestrial species were screened for their ability to oxidize phenolic compounds and digest cellulose in natural and artificial diets. Ligia pallasii (Isopoda: Oniscidea) and Gnorimosphaeroma oregonense (Isopoda: Sphaeromatidea) oxidized dietary...

Cellulose digestion and metabolism by captive rock ptarmigan.

-l, Carbon-14 labeled cellulose was fed to rock ptarmigan to provide evidence of cellulose digestion and metabolism. Digestibility of cellulose and energy metabolized by ptarmigan fed a diet of 6 and 30';0 cellulose were determined by a feeding trial. 2. Recovery of t'~CO2 in expired gases from ptarmigan fed t*C labeled cellulose demonstrates the digestion and metabolism of cellulose by gut mic...
