Distribution of cellulases in the body of Coptotermes formosanus and the probability that the termite uses glucose as an energy and carbon sources
1997 - IRG/WP 97-10202
We assayed extracts of the digestive system and of the whole body of Coptotermes formosanus to determine where the various cellulases, glucose, and related substances were concentrated and to detect pyruvate dehydrogenase activity in the hindgut-removed body in order to verify its full cellulolytic system. About 20%, 18% and 36% of the total exo-1,4-ß-glucanase activity of C. formosanus were dete...

Isolation of a putative endogenous endo-ß-1,4-glucanase (cellulase) from the midgut diverticulae of the wood-boring crustacean, Limnoria quadripunctata
2003 - IRG/WP 03-10494
Over the last 75 years, many workers have conducted research into the digestive biochemistry of Limnoria. Cellulolytic enzymes have been detected in crude extracts, although whether these are of endogenous or microbial origin has been in question. To elucidate the source of these enzymes, RNA was isolated from the midgut diverticulae of Limnoria quadripunctata. Reverse transcription polymerase ...
