Design of silicone interfaces with antibacterial properties
Biofouling. 2023 Jun 30:1-10. doi: 10.1080/08927014.2023.2228206. Online ahead of print.ABSTRACTSilicone implants are widely used for plastic or reconstruction medical applications. However, they can cause severe infections of inner tissues due to bacterial adhesion and biofilm growth on implant surfaces. The development of new antibacterial nanostructured surfaces can be considered as the most promising strategy to deal with this problem. In this article, we studied the influence of nanostructuring parameters on the antibacterial properties of silicone surfaces. Nanostructured silicone substrates with nanopillars of vario...

A method for screening antifouling paints using the CIELAB coordinates of < em > Ectocarpus < /em > sp. under a flow-through condition
Biofouling. 2023 Jun 28:1-11. doi: 10.1080/08927014.2023.2222661. Online ahead of print.ABSTRACTA laboratory test with a flow-through system was designed and its applicability to testing antifouling paints of varying efficacies was investigated. Six different formulations of antifouling paints were prepared to have increased contents (0 to 40 wt%) of Cu2O. The test plates were initially aged for 45 days by rotating them at a speed of 10 knots inside a cylinder drum. A bioassay was then conducted using the alga, Ectocarpus sp., as the test species. The new bioassay for screening antifouling paints under a flow-through syste...

Biofouling occlusion of ships' internal seawater systems: operational, economic, and biosecurity consequences
This study used an engine room simulator and economic evaluation to quantify impacts on commercial ship performance of biofouling occlusion within various ISS nodes (sea chest, strainer, and heat exchangers). A characteristic hockey-stick relationship between occlusion and impact emerged, whereby engine room systems could tolerate up to 55% occlusion of a single node without operational impact, followed by rapid performance deterioration. The relative magnitude of impacts varied by ISS node and in response to changes in ambient seawater temperatures. System tolerance was much lower when simultaneous occlusion of multiple n...

Prodigiosin as an antibiofilm agent against multidrug-resistant < em > Staphylococcus aureus < /em >
Biofouling. 2023 Jun 27:1-15. doi: 10.1080/08927014.2023.2226613. Online ahead of print.ABSTRACTStaphylococcus aureus is known for forming bacterial biofilms that confer increased antimicrobial resistance. Combining antibiotics with antibiofilm agents is an alternative approach, but the antibiofilm ability of prodigiosin (PG), a potential antibiotic synergist, against antimicrobial-resistant (AMR) S. aureus remains to be understood. The antibiofilm activity of PG against 29 clinical AMR S. aureus strains was evaluated using crystal violet staining, and its synergistic effects with vancomycin (VAN) was confirmed using the c...

Initiation and progression of Early-Stage microbial-driven membrane fouling in membrane bioreactors: a review
Biofouling. 2023 Jun 21:1-14. doi: 10.1080/08927014.2023.2226064. Online ahead of print.ABSTRACTMicrobial biofilm development on the membrane surface of bioreactors results in membrane flux decline (biofouling). Biofouling is one of the most severe problems limiting the use of these bioreactors. For detailed understanding of the biofouling, microbial community and dissolved organic matter analyses have been performed in recent decades. Although most previous studies have focused on mature biofilms at the end point of biofouling, understanding of the early stages is crucial to mitigate biofilm formation. Thus, recent studie...
