“…As a preliminary procedure for identifying the intactness of chitin structures in these composites we used a specific chitin stain Calcofluor White (CFW), the fluorescent brightener [26,27,[39][40][41][42][43][44][45][46]. CFW binds to the glucan chains and linear β-(1,4)-glucosidically linked units of N-acetyl-D-glucosamine.…”

“…The thermal stability of chitin under hydrothermal conditions and the presence of various functional groups (-OH and C=O and -NH) in the chitin molecule permit the utilization of this biopolymer in hydrothermal synthesis reactions. Our previously published experimental results showed strong evidence [5][6][7][8][9] that this is a key way to use chitinous matrices of sponge origin as a nanostructured biological scaffold [26][27][28]. A broad variety of reactions related to hydrothermal synthesis can be performed in vitro.…”

range of uses. Here, chitin-based scaffolds isolated from the skeleton of marine demosponge Aplysina aerophoba were used as a template for the in vitro formation of iron oxide from a saturated iron(III) chloride solution, under hydrothermal conditions (pH~1.5, 90 °C). The resultant chitin-Fe 2 O 3 three dimensional composites, prepared for the first time via hydrothermal synthesis route, were thoroughly characterized using light, fluorescence and scanning electron microscopy; as well as with analytical methods like Raman spectroscopy, electron diffraction and HR-TEM. The results show that this versatile method allows for efficient chitin mineralization with respect to hematite. Additionally, we demonstrate that chitin nanofibers template the nucleation of uniform Fe 2 O 3 nanocrystals.

“…Some GH74 hits from Poribacteria genomes encode for proteins with the potential for chitin deacetylation. Chitin is a polysaccharide of N-acetyl-D-glucosamine entities and represents a major component of the skeleton of A. aerophoba (Ehrlich et al, 2010). Glucans also occur in other glycoconjugates, some of which are responsible for self-non-self recognition in sponges (reviewed by Fernandez-Busquets and Burger, 2003).…”

Single-cell genomics reveals complex carbohydrate degradation patterns in poribacterial symbionts of marine sponges

et al. 2013

Many marine sponges are hosts to dense and phylogenetically diverse microbial communities that are located in the extracellular matrix of the animal. The candidate phylum Poribacteria is a predominant member of the sponge microbiome and its representatives are nearly exclusively found in sponges. Here we used single-cell genomics to obtain comprehensive insights into the metabolic potential of individual poribacterial cells representing three distinct phylogenetic groups within Poribacteria. Genome sizes were up to 5.4 Mbp and genome coverage was as high as 98.5%. Common features of the poribacterial genomes indicated that heterotrophy is likely to be of importance for this bacterial candidate phylum. Carbohydrate-active enzyme database screening and further detailed analysis of carbohydrate metabolism suggested the ability to degrade diverse carbohydrate sources likely originating from seawater and from the host itself. The presence of uronic acid degradation pathways as well as several specific sulfatases provides strong support that Poribacteria degrade glycosaminoglycan chains of proteoglycans, which are important components of the sponge host matrix. Dominant glycoside hydrolase families further suggest degradation of other glycoproteins in the host matrix. We therefore propose that Poribacteria are well adapted to an existence in the sponge extracellular matrix. Poribacteria may be viewed as efficient scavengers and recyclers of a particular suite of carbon compounds that are unique to sponges as microbial ecosystems.
