“…These non-marine microbes have limited ability to survive and reproduce in seawater and their populations cannot optimally counterbalance grazing by sponges. In contrast, the only available experiment investigating clearance of a marine pathogenic bacterium (Vibrio anguillarum) by sponges found that the bacteria, rather than decreasing in number, proliferated in the experimental aquaria at the 2 concentrations assayed (Fu et al 2006). Plausible hypotheses are (1) that V. anguillarum was reproducing at a higher rate than grazed by the sponges, or (2) that it could infect the sponges during the experiment, causing diminished feeding.…”

“…Laboratory results prompted suggestions that sponges could be integrated in both fish farms and urban waste water discharge systems, so that besides the benefit of rearing sponge biomass for potential biotechnological uses (cosmetics, natural products, aquariophily etc), the cultured sponges would contribute to decreasing bacterial loads in ambient seawater (e.g. Pronzato et al 1998, Milanese et al 2003, Fu et al 2006, Gifford et al 2007). However, the assumed efficiency of marine sponges to deal with pathogenic bacteria and fungi in a real marine scenario can be deceiving, as this assumption has been derived almost exclusively from feeding experiments using enteric and freshwater microbes.…”

Sponges have traditionally been viewed as rather unselective filter feeders, and therefore as potential biofilters to remediate microbial water pollution. Here we show that the assumed connection between the ability of sponges to feed on microbes and the potential biotechnological use of such an ability to reduce microbial pollution is more complex than assumed. In a laboratory feeding experiment combined with a transmission electron microscopy study, we assessed the potential of the marine sponge Hymeniacidon perlevis to ingest and digest 3 common pathogenic microbes occurring in coastal waters: 2 bacteria (Escherichia coli and Vibrio anguillarum), and 1 marine yeast Rhodotorula sp. All 3 microbes were ingested by the sponge, but selectively, at different rates and following different cellular mechanisms. Yeast cells were processed very atypically by the sponge. Differences in the ingestion and digestion pathways led to large differences in the effectiveness of the sponge to remove the microbes. While sponge grazing reduced the concentration of E. coli and Rhodotorula sp. to levels far below the initial values, sponges were ineffective in abating concentrations of the most infective bacterium, V. anguillarum. This bacterium, which was digested more slowly than E. coli, proliferated in the experimental flasks at much higher rates than it was grazed. These findings raise the question whether sponges are suitable for bioremediation of microbial pollution, since selective or preferential ingestion of certain bacteria by sponges may end up fueling growth of those grazed less, such as Vibrio spp.

Abstract:The reproductive cycle of the demosponge Hymeniacidon perlevis (Montagu) was investigated at the Mar Piccolo di Taranto (Ionian Sea, Apulian). According to the distribution of the specimens, along a bathymetric gradient, sponges have been subdivided in two groups, named group A and group B. The former was made up of specimens that are usually exposed in the air when there is a low water level and the latter by specimens that are constantly submerged. Monthly monitoring (February 2006 -January 2007 of twenty tagged specimens (ten in each group) was carried out in order to compare the reproductive efforts in the two groups. The reproductive pattern differed slightly between the two groups; the majority of the females in group B restrict oocyte production till May. In addition, group A exhibits a significantly higher density of sexual elements, than those belonging to group B. It was hypothesised that the sexual activity of the submerged specimens, living close to the soft bottom, could be influenced by severe anoxic crises due to periodic algal decay, whereas the intertidal specimens, located some decimetres off the soft bottom, and subjected to the moderate water movement, were not affected. The thick algal assemblage associated with the intertidal specimens gives protection against dehydration and solar irradiation during the prolonged periods of air exposure. By September, none of the monitored specimens had survived. The finding of newly developing small specimens in late winter supports a possible colonisation from residual sponge fragments dispersed before mass mortality.

Seasonal differences of the cultivable bacterial communities associated with the marine sponge, Hymeniacidon sinapium, between spring and summer were analyzed through the Amplified Ribosomal DNA Restriction Analysis (ARDRA). For the cultivation of the bacterial isolates, modified Zobell and MA media were used. The 16S rDNA of individual strains were amplified and fragmented by using two restriction enzymes, HaeIII and MspI. As a result, 23 ARDRA types from the spring sponge and 28 types from the summer sponge were obtained. The partial sequencing result of 1 to 3 selected strains from each types showed over 94% similarities with the known species from the public database. The bacterial communities from the sponge, captured on spring, contained 4 phyla: Actinobacteria, Alphaproteobacteria, Gammaproteobacteria, and Firmicutes. There were 5 phyla observed from the bacterial communities associated with the sponge, captured on summer: Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Firmicutes, and Bacteroidetes. Gammaproteobacteria was predominant group in both spring and summer, accounted for 33.8% of total in spring and 67.4% in summer, showed increase pattern on summer. Because Firmicutes and Actinobacteria participated in 30.2% and 8.3% of the spring sponge while they represented only 6.9% and 0% of the summer sponge, both bacterial groups showed decrease drift on summer. Betaproteobacteria (4.7%) and Bacteroidetes (4.7%) were only observed on the sponge captured on summer. On the sponge, Hymeniacidon sinapium, more diverse bacterial communities were shown on summer than on spring, and even from the same sponge, there were seasonal differences. Keywords
