Between the Sponge and the Tap—Bacterial Communities at Overlooked Hospital Hygiene Hotspots [PDF]

Microorganisms
Hospital environments host diverse microbial communities that may contribute to nosocomial infections. Moisture-retaining surfaces such as cleaning sponges and faucet edges represent high-contact, under-investigated hygiene hotspots, particularly in ...

Exploring the Microbial Reservoir of Geodia cydonium (Linnaeus, 1767): Insights into Site-Specific Diversity and Biotechnological Potential [PDF]

Marine Drugs
Marine sponges are recognized as reservoirs of diverse microorganisms that produce bioactive natural compounds. In this study, we conducted a metataxonomic analysis of Geodia cydonium specimens collected from four sites in Italy: Secca delle Fumose (Gulf

Hydrodynamics of sponge pumps and evolution of the sponge body plan

eLife, 2020
Sponges are suspension feeders that filter vast amounts of water. Pumping is carried out by flagellated chambers that are connected to an inhalant and exhalant canal system.

An Innovative IMTA System: Polychaetes, Sponges and Macroalgae Co-Cultured in a Southern Italian In-Shore Mariculture Plant (Ionian Sea)

Journal of Marine Science and Engineering, 2020
In this paper, we report data from the first year of rearing of a set of filter feeder bioremediator organisms: macrobenthic invertebrates (sabellid polychaetes and sponges), coupled with macroalgae, realized in a mariculture fish farm.

The Study of Methylene Blue Loading into Chitosan-graft-Maleic Sponges

International Journal of Technology, 2022
This work succeeded in synthesizing sponges from chitosan-graft-maleic anhydride. Chitosan and maleic anhydride at a certain mass ratio (1:2, 1:1; and 2:1) were reacted in dimethyl sulfoxide (DMSO) at 60? for 24 hours.
