Marine and Industrial Biofouling


Book Description

Biofouling is a costly problem, and it is encountered in a wide spectrum of technical systems, ranging from the shipping industry, power industry, water purification, automobile industry, paint and pharmaceuticals, to the microelectronics and food industries. Micro- and macroorganisms attach to surfaces and accumulate there, forming biofilms that cause interferences – a fundamentally natural process. Usually, a medical paradigm is applied: kill biofilms and the problem is solved. This leads to excessive biocide use. However, the success of this strategy is very limited; furthermore it leads to equipment damage and environmental pollution. Simply trying to kill the fouling organisms is clearly not seen as a successful strategy while cleaning is put forward as much more important. In this book, strategies to prevent adhesion, to mitigate the extent and effects of biofouling, and to detect and remove fouling layers are presented. Holistic approaches to the fouling process are elaborated, taking into account options such as nutrient limitation, repellent and easy-to-clean surfaces for fouling layer limitation, and replacing biocides with more environmentally friendly methods – in other words: learning how to live with fouling biofilms without suffering the damage they can do.




Larvae and Evolution


Book Description

Many biological facts are irreconcilable with the assumption that larvae and adults evolved from the same genetic stock. The author of this book draws attention to these, and presents his alternative hypothesis that larvae have been transferred from one taxon to another. In his previous book (Larvae and Evolution, 1992), the author used larval transfer to explain developmental anomalies in eight animal phyla. In the present book, he claims that the basic forms of all larvae and all embryos have been transferred from foreign taxa. This leads to a new, comprehensive theory on the origin of embryos and larvae, replacing the discredited 'recapitulation' theory of Haeckel (1866). Metamorphosis, previously unexplained, represents a change in taxon during development.




Contamination Mitigating Polymeric Coatings for Extreme Environments


Book Description

​This volume provides perspectives on the approaches, mechanisms, test methods, durability considerations, and environmental concerns for contamination mitigating coatings and polymers with emphasis on their use in more extreme aerospace and marine terrestrial environments. Parts of the Volume are devoted to application of biomimetics to contamination mitigation polymeric coatings, low ice adhesion surfaces, insect residue adhesion resistance coatings, and marine biofouling mitigation materials. By juxtaposing ice insect, and marine mitigation approaches, researchers and users may more easily identify threads of similarity that will assist in future developments and potential applications in these areas. The volume is of interest to chemists and material scientists in providing awareness of both the need for efficacy in mitigating contamination and for appropriate coating durability; to physicists in providing better understanding of the interaction between the contaminant, the coated surface, and the surrounding environment; and to engineers in describing the need for better scale-up tests between laboratory and field environments.




The Biochemistry of Primary Attachment in the Serpulid Larvae Hydroides Elegans


Book Description

The serpulid polychaete, Hydroides elegans, is a prominent fouling organism in tropical marine waters. Fouling is first caused by the formation of an unmineralized primary tube and thread by settling larvae. This is replaced by a mineralized secondary attachment tube during metamorphosis. Biochemical analysis of the primary and secondary tubes suggests a composition rich in acidic amino acids and glycine. Dopa is transiently present in new growth. The latter finding, particularly, may indicate a functional similarity to the adhesive proteins of mussels, ascidians, and sabellariids.




The Origin and Evolution of Larval Forms


Book Description

A classic problem in evolutionary biology is the origin of larvae - how and why did they occur? Indeed, it has often been suggested that many entirely unique body plans first originated as retained larvae of ancestral organisms. But what of the larvae themselves? What developmental and evolutionary forces shape and constrain them? These questions and others are dealt with by this international team of leading zoologists and developmental biologists. Intended to contribute to a continuing dialectic, this book presents diverse opinions as well as manifold conclusions. Certain to challenge and intrique, The Origin and Evolution of Larval Forms should be a part of the library of every evolutionary and developmental biologist interested in larvae and their significance.




Antifouling Compounds


Book Description

Awareness of the dangers of toxic components in antifouling coatings has raised interest in the potential for nontoxic alternatives. Marine organisms from bacteria to invertebrates and plants use chemicals to communicate and defend themselves. This book explores natural based antifoulants, their ecological functions, methods of characterisation and possible uses in antifouling. The text takes on the challenge of identifying such compounds, designing sustainable production and incorporating them into antifouling coatings.
