Abstract: The present invention relates to the field of wood rosin and resin acid derivatives and more particularly to abietane-type diterpenoids as well as different uses thereof. Furthermore, the present invention relates to methods of coating surfaces, preventing, reducing or inhibiting bacterial biofilm formation, and treating or preventing disorders caused by microbial growth and viability as well as bacterial colonization.

Abstract: The invention relates to a method of inhibiting the biofilm formation by thermophilic adhering microbes of paper and board machines on the surfaces of paper or board machines, and/or removing such biofilms from the said surfaces by adding to the circulation waters of the paper or board machines at least one pure substance isolated from a plant or at least one plant extract or a mixture thereof in such a concentration which is effective against thermophilic adhering microbes. The invention further relates to a method of determining the need of the addition of an anti-biofilm agent in paper and board manufacturing processes, and an assembly kit suitable for the same.

Abstract: The invention relates to natural and synthetic compounds, plant extracts and compositions containing them and mixtures of these in the treatment and/or prevention of a chlamydial infection. Medicinal preparations, food additive compositions and functional foodstuffs can be prepared from the plant-derived phenolic compounds and synthetic compounds and plant extracts.
