Biochemical and biophysical characterization of collagens of marine sponge, Ircinia fusca (Porifera: Demospongiae: Irciniidae)

Collagen from the Marine Sponges Axinella cannabina and Suberites carnosus: Isolation and Morphological, Biochemical, and Biophysical Characterization

“…In addition to these, macromolecules have gained interest since such biopolymers possess a wide range of bioactivities that can find applications in the biomedical sector. Collagen has been isolated from different marine sponges, e.g., Spongia graminea , Microciona prolifera , Haliclona oculata [22], Hippospongia communis , Cacospongia scalaris [23], Geodia cydonium [24] Chondrosia reniformis [25,26], and various Ircinia species [27], and in certain cases has shown high potency in tissue regeneration [28]. Although the importance of marine collagen has been recognized, only a few thorough investigations on marine sponges have so far been reported [25,27,29], probably due to its characteristic insolubility and mineralization, which cause difficulties in its isolation and characterization [30,31].…”

Morphometric, elemental and biochemical characterisation of threeHaliclonaspecies (Demospongiae) from the Gulf of Mannar, India

“…It is known that species belonging to the same genera may not produce same molecules and hence, the architecture of individual species may be an important aspect to pursue along with isolation of novel molecules. Hence, the species distribution patterns, morphological and anatomical variations within the species may influence the production of different kinds of therapeutic agents and as an alternative potential source of collagen (Gunda and Janapala, 2009;Luter and Duckworth, 2010;Pallela et al, 2011a). Our recent reports on H. tenuiramosa, Neopetrosia similis, Petrosia (Xestospongia) testudinaria and Petrosia nigricans also suggest the use of marine sponges as bioindicators and biomonitors for assessing pollution parameters and chemical speciation in any sustainable ecosystem (Rodrigo et al, 1994;Venkateswara Rao et al, 2009).…”

“…Marine sponges, especially the demosponges, have attracted significant attention from various scientific disciplines because of their possession of chemical molecules and proteins such as collagens (Venkateswarlu et al, 1994;Zhou and Molinski, 2003;Pallela et al, 2011a). As they produce various novel chemical molecules, sponges have been of great interest to chemists and have led to biotechnological applications and potential for drug discovery.…”

Evolving Marine Biomimetics for Regenerative Dentistry

“…However, the size range is equal to the size of structure for an essential functional unit of tissue [125]. The sponge fibers are fully bonded, and the mixture of collagens blended into the fibers is constitutively made up from analogues (short chain) of basement membrane collagens, such as collagen type IV [126,127]. In one specified marine sponge a type 1 mammalian analogue has been discovered [128].…”
