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 ...

The natural durability of five Indonesian timber species against marine borers - A field test in Indonesia
1981 - IRG/WP 474
This paper presents results of a natural durability field test using five species of Indonesian timbers against marine borers. An attempt is also made to assess any difference in durability between the lower and upper part of the trunks. Results of marine fungal identification, soft-rot assessment, and marine-borer assessment of CCA-treated test blocks will be reported in separate papers...

New insights from NMR, FTIR, X-ray diffraction and physical chemistry into digestive processes in the wood-boring marine crustacean Limnoria quadripunctata
2010 - IRG/WP 10-10732
This paper summarises preliminary findings of a multi-technique exploration of the degradation of lignocellulose in the marine isopod Limnoria quadripunctata. Scanning electron microscopy revealed connections between the digestive gland and the hindgut that would permit the exchange of fluids between the two organs while the food mass is retained in place within the hindgut. This enables enzymes t...

Wood modification reduces the feeding rate of the wood boring crustacean, Limnoria quadripunctata
2022 - IRG/WP 22-10993
Adult Adult Limnoria search for new wood once their current piece disintegrates from tunnelling. During this time, they do not have access to wood so experience a period of starvation and must feed again once settled. Wood modification offers protection to marine structures by reducing the feeding rate of Limnoria and therefore can reduce recruitment of adults from distant pieces of wood. Chemical...
