AMINO ACID PROFILE OF EARTHWORM AND EARTHWORM MEAL (Lumbricus rubellus) FOR ANIMAL FEEDSTUFF

Purification and characterization of six fibrinolytic serine-proteases from earthworm Lumbricus rubellus.

The six lumbrokinase fractions (F1 to F6) with fibrinolytic activities were purified from earthworm Lumbricus rubellus lysates using the procedures of autolysis, ammonium sulfate fractionation, and column chromatography. The proteolytic activities on the casein substrate of the six iso-enzymes ranged from 11.3 to 167.5 unit/mg with the rank activity orders of F2 > F1 > F5 > F6 > F3 > F4. The fi...

Earthworm Lumbricus rubellus MT-2: Metal Binding and Protein Folding of a True Cadmium-MT

Earthworms express, as most animals, metallothioneins (MTs)-small, cysteine-rich proteins that bind d(10) metal ions (Zn(II), Cd(II), or Cu(I)) in clusters. Three MT homologues are known for Lumbricus rubellus, the common red earthworm, one of which, wMT-2, is strongly induced by exposure of worms to cadmium. This study concerns composition, metal binding affinity and metal-dependent protein fo...

Evaluation of DNA damage and lipoperoxidation content in red earthworm, Lumbricus rubellus exposed to zinc oxide nanoparticles

Manufactured nanoparticles have a wide range of application due to their advantageous properties whencompared with their bulk forms. There is a growing concern regarding the safety of nanoparticles. This studyaimed to evaluate the cell membrane lipoperoxidation (LPO) and DNA integrity in red earthworm Lumbricusrubellus when exposed to artificial soil systems containing different concentration o...

Ceramide glycanase from the earthworm, Lumbricus terrestris.

Ceramide glycanase (CGase) is an enzyme that cleaves the linkage between the sugar chain and the ceramide. To make this enzyme readily available, we have developed a simple method for preparing it from the earthworm, Lumbricus terrestris. The method involves Bio-Gel A-0.5m, octyl-Sepharose and p-aminophenylthiogalactoside-agarose column chromatography. By gel filtration, the molecular mass of e...
