Monitoring coating condition in ballast tanks

Safety of ships and offshore installations is continuously an area of attention for owners, operators and authorities. Standard practice of today requires regular inspections of the hull and machinery. The results of inspections as carried out by various parties may well not be shared amongst each other. This means that enormous amounts of data...

Visualization of capsular polysaccharide induction in Acidithiobacillus ferrooxidans

Extracellular Polymeric Substances (EPS) are of fundamental importance for attachment to metal sulfides, biofilm formation and leaching efficiency of Acidithiobacillus ferrooxidans. In this work we have visualized the capsular polysaccharides (CPS) of A. ferrooxidans ATCC 23270 using the fluorescently-labeled lectin Concanavalin A (ConA) and...

Remote sensoring for an offshore windfarm maintenance system

In the current offshore wind energy market high cost efficiency is a major factor. While budgets become more limited, the demands for the structures are constantly increasing. Wind turbine park owners (and operators) now request a lifetime of 25 years or more for their off shore structures. The integrity of wind turbine structures can be...

Mars-relevant microorganisms in simulated subsurface environments under hydration/dehydration conditions

Influence of biofilms on colloid mobility in the subsurface

Transport processes in subsurface environments are determined by complex interactions between the soil matrix and dissolved as well as particulate substances. Biofilms play an important role in the transport of colloids in the subsurface, since biofilms cover the solid soil matrix and hence influence the interaction of colloids with the soil...
