Bacterial adherence to host tissues is regarded as an important initial step for colonisation and infection. Hence, agents that interfere with the ability of pathogens to adhere to host cells are promising antidotes. In anti-adhesion therapy, alternative adhesion matrices are orally supplied to competitively bind enteropathogens, thus preventing colonisation and disease. A miniaturised adhesion test (Becker et al., 2007) was applied to analyse the binding capacity of food and feed ingredients for bacterial cells. Different by-products of plant processing were tested in terms of their binding capacity for bacteria in the framework of the EU-project SAFEWASTES, with the aim of turning organic waste into healthy feed. In addition, mannose-containing plant materials such as konjac and locust bean gum were tested, for the most common binding ability described with bacteria up to now is mannose-directed adhesion.
