MARINE BORER ALDEHYDE OXIDASE

Canadian Journal of Zoology, 1965
A very active and specific enzyme, aldehyde oxidase, has been demonstrated and partially purified from the digestive tract of the marine borer, Bankia setacea (Tryon). In the presence of the enzyme, the substrate vanillin was oxidized to vanillic acid with the simultaneous reduction of oxygen, cytochrome c, 2,6-dichlorophenolindophenol, or methylene ...

Control of Marine Borers in Plywood

Journal of Fluids Engineering, 1947
Abstract This series of tests on plywood veneers was originally prepared for company use to assist the war effort on a confidential basis, which has now been removed. The results indicate that the addition of a siliceous extender to the adhesive used in bonding the plywood prevents the penetration beyond the first veneer of Limnoria ...

MARINE BORER STUDIES: EVALUATION OF TOXICANTS

Canadian Journal of Zoology, 1955
Of 115 compounds tested for toxicity to adult Bankia setacea imbedded in wooden blocks, the most toxic was sodium arsenite, which gave a complete kill at 25 p.p.m. (as arsenic trioxide) after 18 hr. exposure. The relative toxicity of chemically pure sodium arsenite and various commercial concentrates to Bankia setacea was measured.

HARBOR SCREENING TESTS OF MARINE BORER INHIBITORS - III.

1961
The Naval Civil Engineering Laboratory is exposing wood panels impregnated with various materials to determine the resistance of these panels to attack by marine borers. The report lists the results of harbor tests of treated panels removed from exposure between 15 February 1967 and 15 November 1968.

Survey of Marine Borers in Canadian Atlantic Waters

Journal of the Fisheries Research Board of Canada, 1970
A survey of the maritime waters of Canada's Atlantic provinces disclosed only the teredine borer Teredo navalis and the limnorial borer Limnoria lignorum. The distribution of L. lignorum was virtually ubiquitous, whereas T. navalis was confined to areas where water temperatures exceeded 15–16 C for some period of the year.

THE OCCURRENCE OF PROTOPORPHYRIN AND MYOGLOBIN IN THE MARINE BORER, BANKIA SETACEA (TRYON)

Canadian Journal of Zoology, 1965
The pigment observed in the siphons of the marine borer, Bankia setacea (Tryon), was isolated and identified as protoporphyrin. Myoglobin was isolated from the posterior adductor and heart muscles.

Estimation of Marine-Borer Attack on Wooden Surfaces

Journal of the Fisheries Research Board of Canada, 1967
Bankia setacea prefer to attack upper horizontal wooden surfaces, whereas Limnoria spp. prefer the lower surfaces. Attack by B. setacea is heaviest at the mudline and decreases almost linearly with decreasing depth. Limnorial attack is heaviest in the intertidal zone, then is relatively constant with increasing depth.

Navy Research on Marine Borers and the Laboratory Culturing of Limnorians

OCEANS '78, 1978
The Naval Research Laboratory's investigation of the protection of wood in marine service which began with an in depth study of creosote, is now concentrating on a study of the active antiborer constituents of naturally bioresistant woods. This work is now focussing on woods which are resistant to limnorians, marine crustacean isopods, because most ...

Standard Toxicity Evaluation of Chemicals Poisonous to the Marine Borer

1960
Many investigators have studied the toxicity of chemical agents to wood-destroying organisms, but the majority of the investigators have been concerned only with wood-destroying fungi. In general, those who have studied the toxicity of chemical agents to marine borers have considered rapid kill rather than low concentration to be the criterion of high ...

Energy metabolism in the caecum of the marine borer, Bankia setacea

Journal of Experimental Marine Biology and Ecology, 1974
Abstract Intact caeca of the marine borer, Bankia setacea (Tryon), were incubated in vitro with (1- 14 C)- and (6- 14 C)-glucose. The specific yields of 14 CO 2 from (1- 14 C)- and (6- 14 C)-glucose were found to be 9 and 1% respectively. From these values the contribution of the pentose cycle to the overall glucose metabolism was calculated as
