Antibacterial (e.g. Bacillus subtilis, Escherichia coli, Rodococcus rodochrous, Micrococcus luteus, Microbacterium imperale, Proteus vulgaris...), antifungal (e.g. Candida albicans), virucidal (e.g. HIV, herpes) and spermicidal. Linked applications: anti-acne, anti-dandruff, deodorants (Staphylococcus and Corynebacterium).
Treatment of sepsis and septic shock in humans and animals.
Induction of protein production (e.g. amylase, laccase, cellulose).
Formulation aid: Solubilizer (e.g. essential oil in water) / ajuvant (e.g. pesticides) / defoamer / wetting agent / antimicrobial booster.
All products are now listed in their most 'purified' (dried) form (best stability for long time storage). They can also be supplied as concentrated liquids/gels/pastes, which can make formulation easier. Only products with a C18:1 fatty acids chain are displayed in the figures, but C18:2, C18:0, C16:0 and C16:1 intermediates are also present in these samples in small amounts. When only the C18:1 intermediate (or another chain length) is required, these products can be produced, but these products are not (yet) offered as a standard.
