Biodeterioration of polyethylene by jellyfish nematocyst protein
Marine Pollution Bulletin, 2023Plastic pollution is one of the major global problems existing now-a-days and has become a cause of serious concern in coastal and marine ecosystems. Increased accumulation of plastics in the aquatic environment by anthropogenic sources results the alteration of the aquatic ecosystem and its functioning.

Beachside preparation of jellyfish nematocyst tentacles
Toxicon, 1992A comparison of methods for preparing a jellyfish nematocyst suspension from sea nettle (Chrysaora quinquecirrha) fishing tentacles at the beachside was conducted. Autolysis of the tentacle followed by straining and sedimentation on ice was found to be a satisfactory technique.

Zootaxa, 2006
Nematocysts (stinging organelles) are an important part of cnidarian identification, but the cnidomes of many species remain poorly known because of identification difficulties and confusing nomenclature. Currently, the cnidomes of 20 cubozoan species are documented in whole or in part (including four undescribed species and five newly described ...

Tissue and Cell, 1984
Some nudibranchs that feed on cnidarians are known to store nematocysts within cnidophage cells and use them for their own defense. Most of the nematocysts are in direct contact with the cytoplasm of the cnidophage. Nematocysts are not subjected to lysosomal enzymes because any phagocytic membrane that surrounded the nematocyst after engulfment does ...

Cobalt Staining OfActinia EquinaNematocysts
Stain Technology, 1978Nematocysts of Actinia equina are stained black by incubation in 2% CoCl2 followed by an aqueous wash and H2S treatment. They are also stained positively by morin. Nematocysts isolated from the acrorhage were found to have a high concentration of calcium of which only 30% was "free." It is suggested that the high concentration of calcium in the ...

Sea nettle Chrysaora quinquecirrha) nematocyst venom hemagglutinins
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1983Abstract 1. Sea nettle nematocyst venom contains hemagglutinins specific for human and rabbit erythrocytcs. 2. These hemagglutinins exist as multiple molecular forms based on their behavior on DEAE cellulose and SDS-PAGE. 3. Hemagglutinin activity was not inhibited by several simple mono- and disaccharides, but was inhibited by dextran sulfate and ...

Fibrous Mini-Collagens in Hydra Nematocysts
Science, 1994Nematocysts (cnidocysts) are exocytotic organelles found in all cnidarians. Here, atomic force microscopy and field emission scanning electron microscopy reveal the structure of the nematocyst capsule wall. The outer wall consists of globular proteins of unknown function. The inner wall consists of bundles of collagen-like fibrils having a

A Disulfide-Linked Collagenous Protein of Nematocyst Capsules
Science, 1966The major protein component present in the capsule and thread of a sea anemone nematocyst consists of monomers of a collagen-like protein linked by disulfide bonds. Purified nematocyst capsules and threads are rich in hydroxyproline, and dissolved by disulfide reducing agents.
