The dermis of sea cucumbers is a catch connective tissue or mutable collagenous tissue that shows large changes in stiffness. Extensive studies on the dermis revealed that it can adopt three different states having different mechanical properties that can be reversibly converted. These are the stiff, standard and soft states. The standard state is readily produced when a dermal piece is immerse...

Fucodians extracted from sea cucumbers (SC-FUCs) possess linear chains with uniform repeating units. Sulfation patterns endow SC-FUCs unique structures and bioactivity. The present study investigated the anti-hyperlipidemic activity of two fucodians isolated from sea cucumbers Pearsonothuria graeffei (fuc-Pg) and Isostichopus badionotus (fuc-Ib). The results indicate fuc-Pg dominated with a 4-O...

The Malayan term trepang describes a variety of edible holothurians commonly known as sea cucumbers. Although found in temperate and tropical marine waters all over the world, the centre of species diversity and abundance are the shallow coastal waters of Island Southeast Asia. For at least 300 years, trepang has been a highly priced commodity in the Chinese market. Originally, its fishing and ...

BACKGROUND The objective of this study was to determine the residual concentrations of ethion and imidacloprid in cucumbers grown in greenhouse. The effect of some simple processing procedures on both ethion and imidacloprid residues were also studied. METHODS Ten active greenhouses that produce cucumber were randomly selected. Ethion and imidacloprid as the most widely used pesticides were m...

AIMS To evaluate the interaction between selected yeasts and bacteria and associate their metabolic activity with secondary cucumber fermentation. METHODS AND RESULTS Selected yeast and bacteria, isolated from cucumber secondary fermentations, were inoculated as single and mixed cultures in a cucumber juice model system. Our results confirmed that during storage of fermented cucumbers and in ...

In order to search for sulfated polysaccharides in different invertebrate connective tissues and to examine their biological activities, we have isolated three types of polysaccharides from the body wall of the three sea cucumbers Holothuria edulis, Apostichopus japonicas and Holothuria nobilis. The physicochemical properties and anticoagulant activities of these polysaccharides were examined a...
