    Opis:
    The present review deals with the bioactive compounds of the marine non-chordates. The potent medicinal usage of the bioactive compounds viz. steroids, terpenoids, isoprenoid and non-isoprenoid compounds, quinones, brominated compounds, nitrogen heterocyclics and nitrogen-sulphur heterocyclics from marine non-chordates have been compiled. Various literatures survey revealed that the bioactive compounds isolated in recent past from the marine poriferans, cnidarians, annelids, arthropods, molluscs and echinoderms could be rich sources of therapeutic agents having antibacterial, antiinflamatory, anticarcinogenic properties. In overall, the present study will be benefitted to know global drug discovery researches on bioactive compounds from marine organisms for students, scholars, scientists, pharmaceutical sector, and government regulating authorities as new challenging technology in clinical applications through medicines.

    Opis:
    The Chandipore beach, situated in Balasore district, Odisha, 21°28΄N 87°01΄E / 21.47°N and 87.02°E shows an interesting nature of wave action as the water recedes up to an average of 5 kilometres during the ebb and tide, resulting in a vast, dynamic array of coastal biodiversity. It gets exposed to a huge tourism load every year and is faced with multidimensional anthropogenic interactions manifested through a varying gradient of urbanizing parameters like cattle grazing, automobile exhaust, constructions in vicinity of beach area, sewage and solid disposals etc. Present piece of work aims at documenting the premonsoon abundance and diversity of marine invertebrate fauna in this eastern Indian sea beach. Adamsia palliata, Carcinoscorpius rotundicauda, Diogenes rectimanus, Sabella sp., Astropecten mauritianas were found to be few of the prominent faunal representatives. Significant differences in respect of species richness have been observed among different selected ecozones through the coastal landscape based on tidal activity and anthropogenic exposure (F5.73, p ≤ 0.05). Such type of field-based observations leads to the scope of further estimation of the ecological status of these native organisms, their intra and inter-specific associations and functional contributions to coastal landscape playing role as a potential bioindicator, which may in turn become instrumental in frame working the future conservation scheme of these natural assets.

    Opis:
    The muscles and internal organs of marine animals contain many proteases. These enzymes fulfill different metabolic functions in the living organisms and affect the sensory quality and functional properties of the catch. Their activity depends on the species, life cycle, and the feeding status of the organism. Many proteases of marine origin differ from their counterparts in terrestrial animals in being more active at lower temperature and less resistant to thermal denaturation. Of practical importance in the industry is their role in ripening of salted fish, fish sauces and marinades, modyfying fish protein concentrates, ensilaging of seafood offal, and deskinning of fishery products. The negative effects comprise mainly the early post morten quality degradation of the catch and deterioration of the rheological properties of fish gels. Proteolytic preparations form different marine sources may be used successfully in food processing and as industrial enzymes, e. g. tanning agents.

    Opis:
    Muscle proteases are located mainly in the lysosomes, in the sarcoplasm, and in the extracellular matrix of the connective tissue surrounding each cell. The lysosomal proteases, cathepsins, have optimum activity in the acidic range, although many of them retain high activity also 1 or 2 pH units away from the optimum value. Among the cathepsins there are endopeptidases and exopeptidases. Most cathepsins hydrolyse several proteins of the myofibrils. The major protease of the lysosomes in fish and squid muscles is cathepsin D, an aspartyl endoproteinase. Although it is present in the muscle fibre itself, its generally rather low activity at low temperature limits its significance in tenderization of refrigerated fish of most species. Cathepsin L, a cysteinyl protease, is involved in autolysis and softening in matured chum salmon. Cathepsin B, a cysteinyl carboxypeptidase, is capable to attack also some myofibrillar proteins. Cathepsin A or carboxypeptidase A, and cathepsin C, a dipeptidyl hydrolase and dipeptidyl transferase, contribute to the hydrolysis of muscle proteins in a concerted action with the other cathepsins.
