Seeking a method for controlling the implantation of yeasts during alcoholic fermentationWe are interested in knowing if during the alcoholic fermentation yeasts that are fermenting are the same ones that have been inoculated. The molecular method we use is long, we need 2 days to obtain the yeast colony, 1 day to get enough biomass and finally, 1 day to obtain de mitocondrial DNA and do the electrophoresis to know the result. We would like to go faster in obtaining the yeast and the biomass needed to get the result, especially.

Seeking hyperbranched, non charged, short molecules/dendrimers able to be coupled to keratinous surfacesWe are seeking for molecules/compounds/materials which are chemically composed of two opposite parts (see Fig.). The first part of such molecules has a hyperbranched/dendrimer-like/fork shape. The second part (which is geometrically opposit to the first) is a moiety which will favour attachement. The attachment on the skin or hair surface could be generated by adhesion, covalent bonding, electrostatic attachment etc. For instance such latter moieity could react with free amines present on the hair fibers (more attachment points on the skin and hair could be considered, e.g. hydroxyl groups). Lactone groups are an example reported in literature of a reactive moiety which upon heat application can bound to the free amine of the hair. Once bounded to the skin/hair such molecules will work as molecular spacers. The molecules need to be neutrally charged, rigid, branched and have a low particle density (number of atoms in a physical volume). They will therefore decrease the interaction (e.g. Van der Walls attactions) between external particles (such as sand or dust) and the functionalized surface. Example: N-Glycans are an example of such molecular spacers and an example of desired geometrical structure. Glycan with 5 Mannose units for instance will occupy a Volume of 2.25 x 1.65 x 1.24nm with 162 atoms, which lead to a particle density of 35 x 10(^27) atoms/m^3. Such lower particle density will lead to a reduction of the Hamaker-interaction coeffiecint between the funcitonalized surface and an approaching particle. Such molecule will therefore lead to a decrease of the friction coefficient and adhesion forces.
