Cellulose Digestion By The Silverfish Ctenolepisma Lineata

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

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...

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...

Digestion of crystalline cellulose substrates by the clostridium thermocellum cellulosome: structural and morphological aspects.

The action of cellulosomes from Clostridium thermocellum on model cellulose microfibrils from Acetobacter xylinum and cellulose microcrystals from Valonia ventricosa was investigated. The biodegradation of these substrates was followed by transmission electron microscopy, Fourier-transform IR spectroscopy and X-ray diffraction analysis, as a function of the extent of degradation. The cellulosom...

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-...
