In addition to causing problems in wells, the bacteria may colonize tanks and water treatment devices, as well as spring outfalls. Biofouling is a common problem reported in power plants and desalinization factories that use running seawater (e.g., Azis,Al-Tisan&Sasikumar,2001; Railkin,2003), and can affect water quality and hydrodynamic patterns (Flemming&Geesey,1991). The low bacterial abundances in our running seawater aquaria may, therefore, have been caused by Killing, however, is not cleaning while frequently the presence of biomass and not its physiological activity is the problem. 4.

“We became aware that biofouling was a big problem when we heard about the invasive fanworms in the Auckland harbour,” says doctoral student Christopher Walker. Walker, and fellow doctoral student and company partner Patrin Illenberger, (both in ABI’s Biomimetics Laboratory) brought their bioengineering training to bear on the problem.

The process of growth and accumulation of barnacles, mussels, algae and various organisms on ship hulls and other submerged structures, known as marine biofouling, is a long-standing problem closely related to the efficiency and safety of human activities and properties in marine environments. Biofouling is a particular problem for underwater structures, such as pipelines, cables, fishing nets, and bridge pillars. The adverse effects of ship hull biofouling (Figure 1) include [1]: (i) Higher fuel con-sumption because the frictional resistance increased due to biofouling, making the hull rougher and the ship heavier. Biofouling is the colonization of submerged surfaces, produced by unwanted organisms such as bacteria, algae, and barnacles.

That explanation sounds fairly straightforward, but there are several organisms that cause biofouling, many different types of surfaces affected by it, and, due to the BIOFOULING. I. nvasive aquatic species (IAS) — via “biofouling” — is one problem that has now been identified by the International Maritime Organization as a significant environmental threat. Biofouling occurs as the result of an accumulation of aquatic organisms such as micro-organisms, plants or animals on surfaces and structures immersed in or Marine biofouling is a worldwide problem that affects commercial interests in the form of cost, schedule and maintenance impacts. It also affects the environment, as invasive species can be transported across the world, or from river to pond. For many years, efforts to control aquatic nuisance species (ANS) have Biofouling (the colonisation of an interface by a diverse array oforganisms) is almost always a problem where it occurs, as itnegatively affects surfaces, the materials that they are made fromand the structures that they form, and can evendestroy them. Biofouling is a bioﬁlm phenomenon and based on the fact that bioﬁlms grow at the expense of nutrients; oxidizing biocides can make things even worse by breaking recalcitrant molecules down into biodegradable fragments. “We became aware that biofouling was a big problem when we heard about the invasive fanworms in the Auckland harbour,” says doctoral student Christopher Walker.
