“…Other natural compounds, such as extracts from shellfish periostracum, exhibit strong AF properties and can be designed for commercial use. For example, periostracum dichloromethane extracts containing oleamide reduce algal spore settlement (Kang et al 2016), and crude periostracum extracts inhibit the attachment of barnacles, diatoms and marine bacteria (Bers et al 2006). Shellfish periostraca and biogenically derived microtopographies present a nontoxic, environmentally friendly substratum to prevent the settlement and attachment of a range of fouling organisms.…”

Biofouling in marine aquaculture: a review of recent research and developments

Biofouling in marine aquaculture is one of the main barriers to efficient and sustainable production. Owing to the growth of aquaculture globally, it is pertinent to update previous reviews to inform management and guide future research. Here, the authors highlight recent research and developments on the impacts, prevention and control of biofouling in shellfish, finfish and seaweed aquaculture, and the significant gaps that still exist in aquaculturalists' capacity to manage it. Antifouling methods are being explored and developed; these are centred on harnessing naturally occurring antifouling properties, culturing fouling-resistant genotypes, and improving farming strategies by adopting more sensitive and informative monitoring and modelling capabilities together with novel cleaning equipment. While no simple, quick-fix solutions to biofouling management in existing aquaculture industry situations have been developed, the expectation is that effective methods are likely to evolve as aquaculture develops into emerging culture scenarios, which will undoubtedly influence the path for future solutions.

“…Our previous study showed that the shells of larger Lunella tended to be more worn out than those of smaller ones (Osawa & Tokeshi, 2018), leading to different microhabitat characteristics compared with intact shell surfaces (Figure 1c). In this respect, note that the molluscan periostracum is known to inhibit the attachment of sessile organisms; the intact periostracum of Mytilidae with ripple‐like microtopography with specific chemical substances such as diethyl ether and dichloromethane fractions inhibits the settlement of marine bacteria, diatom, and cyprids larvae (Bers, D'Souza, Klijnstra, Willemsen, & Wahl, 2006; Bers & Wahl, 2004; Bottjer, 1981; Kaehler, 1999; Kang et al, 2016; Scardino, De Nys, Ison, O'Connor, & Steinberg, 2003). It is therefore possible that lack of the antifouling periostracum in larger Lunella individuals might facilitate colonization by epibionts.…”

The patterns of microhabitat use were investigated in three coexisting epizoic algae on an intertidal gastropod, Lunella correensis in an attempt to enhance understanding of the niche relations among ecologically similar species in a space-limited environment. Our analysis of field-derived data showed clear spatiotemporal partitioning of shell microhabitats by epizoic algae with different degrees of resource specialization. As a substrate-specializing, obligate epizoic alga, Pseudocladophora conchopheria occupied wider micro-niches on the host of different sizes than facultative epizoic algae (encrusting rhodophytes, crustose Corallina and Gelidium). While Pseudocladophora demonstrated uniform use of all shell microhabitats on hosts of all sizes, crustose Corallina and Gelidium showed more varied microhabitat use with shifting positions on hosts of different sizes. Furthermore, in addition to slight differences in microhabitat use, crustose Corallina and Gelidium demonstrated differences in their interspecific relationship with Pseudocladophora. Our generalized linear models (GLM) analyses indicated that the occurrence/abundance of crustose Corallina was negatively affected by Pseudocladophora but that of Gelidium was positively affected, while Pseudocladophora appeared to be competitively inferior to both rhodophytes when they co-occurred on hosts of relatively large sizes. The present study, therefore, points to variable niche partitioning among algae even on a small spatial scale, which may result from complex interactions between spatio-temporal substrate heterogeneity on a live host and interspecific interactions.

“…To ease the removal of periostracum, the seashells were immersed in a vinegar and seawater solution (1:2), taken in a 250 mL beaker, and left undisturbed for 24 hours. Periostracum was removed from the shell with the help of sterile forceps and retained for further experimental [11].…”

This study aimed to investigate the anti-adherent property of the seashell surface and periostracum to prevent the formation of Streptococcus mutans biofilm. Materials and methodsThe seashells were initially collected from the natural urban beach, and an antibiofilm assay of the shells with and without periostracum was performed against Streptococcus mutans. Furthermore, the seashells were analyzed with a stylus profilometer (Mitutoyo Surftest SJ-301, Mitutoyo America Corporation, Illinois, USA), atomic force microscope (AFM; Nanosurf Easyscan 2, Nanosurf Inc., USA), contact angle assessment, Fourier-transform infrared (FTIR) spectroscopy analysis, and scanning electron microscopy (SEM; JEOL USA, Inc., FE-SEM IT800, Massachusetts, USA) analysis. The ability of seashells to prevent the attachment of Streptococcus mutans and form a biofilm with and without periostracum was studied by crystal violet assay. ResultsThe results revealed that shells without periostracum promoted higher biofilm formation when compared to those having intact periostracum (by 15%, p<0.001). Shell 1 showed the highest biofilm formation, whereas shell 3 showed the least biofilm formation due to the differences in their surface morphologies. The remaining shells (4, 2, 6, and 5) showed interspersed biofilm formation. ConclusionIn summary, our study was able to correlate the topologies of the shell surface with the biofilm formed by Streptococcus mutans with the wetting behavior of those shell surfaces and their roughness. More hydrophobic surfaces (with intact periostracum) were observed to lead to less attachment (correlation coefficient=-0.67). This study can pave the way for designing such biomimetic surfaces to prevent bacterial attachment.
