Towards an absolute scale for adhesion strength of ship hull microfouling.

Biofouling 2019 Apr 10:1-15. Epub 2019 Apr 10.

a Department of Mechanics and Maritime Sciences , Chalmers University of Technology , Gothenburg , Sweden.

In-water ships' hull cleaning enables significant fuel savings through removal of marine fouling from surfaces. However, cleaning may also shorten the lifetime of hull coatings, with a subsequent increase in the colonization and growth rate of fouling organisms. Deleterious effects of cleaning would be minimized by matching cleaning forces to the adhesion strength of the early stages of fouling, or microfouling. Read More

David Emerson

Biofouling 2018 Oct 14;34(9):989-1000. Epub 2019 Jan 14.

a Bigelow Laboratory for Ocean Sciences , East Boothbay , ME , USA.

Lithotrophic iron-oxidizing bacteria depend on reduced iron, Fe(II), as their primary energy source, making them natural candidates for growing in association with steel infrastructure and potentially contributing to microbially influenced corrosion (MIC). This review summarizes recent work on the role of iron-oxidizing bacteria (FeOB) in MIC. By virtue of producing complex 3-dimensional biofilms that result from the accumulation of iron-oxides, FeOB may aid in the colonization of steel surfaces by other microbes involved in MIC.

Biofouling 2018 Nov 4:1-19. Epub 2018 Nov 4.

b Departamento de Edafoloxía e Química Agrícola, Facultade de Farmacia , Universidade de Santiago de Compostela , Santiago de Compostela , Spain.

This study evaluated whether exposing samples of granite colonized by a natural biofilm to artificial daylight or UV-A/B/C irradiation for 48 h enhanced removal of the biofilm with a chemical product previously approved for conservation of monuments by the European Biocide Directive. Rodas granite, which is commonly found in stone-built heritage monuments in Galicia (NW Spain), was naturally colonized by a sub-aerial biofilm. The efficacy of the cleaning method was evaluated relative to uncolonized surfaces and colonized control samples without previous irradiation, treated by dry-brushing or with benzalkonium chloride.

a Advanced Institute of Water Industry , Kyungpook National University , Daegu , Republic of Korea.

In this study, the seasonality of the biofouling behavior of pilot-scale membrane bioreactors (MBRs) run in parallel with vacant sheets and quorum quenching (QQ) sheets using real municipal wastewater was investigated. QQ media delayed fouling, but low temperatures caused severe biofouling. The greater amount of extracellular polymeric substances (EPSs) produced in cold weather was responsible for the faster biofouling of a membrane, even with QQ media. Read More

Non-indigenous species contribute equally to biofouling communities in international vs local ports in the Biobío region, Chile.

Biofouling 2018 Oct 24:1-16. Epub 2018 Oct 24.

a Departamento de Ecología, Facultad de Ciencias, Centro de Investigación en Biodiversidad y Ambientes Sustentables (CIBAS) , Universidad Católica de la Santísima Concepción , Concepción , Chile.

Growing coastal urbanization together with the intensification of maritime traffic are major processes explaining the increasing rate of biological introductions in marine environments. To investigate the link between international maritime traffic and the establishment of non-indigenous species (NIS) in coastal areas, biofouling communities in three international and three nearby local ports along 100 km of coastline in south-central Chile were compared using settlement panels and rapid assessment surveys. A larger number of NIS was observed in international ports, as expected in these 'invasion hubs'. Read More
