摘要:
The present invention relates to the cosmetic use of a lysate of a bacterium or bacteria belonging to the Vitreoscilla sp. genus (in particular the species: Vitreoscilla filiformis) in a complete fermentation medium, as an active agent for preventing and/or treating dandruff conditions of the scalp, including dandruff conditions of the scalp associated with a prevalence of pathogenic microorganisms on the scalp and/or an imbalance of the scalp ecoflora.

摘要:
Sensitive skin, mucous membranes and scalps are treated by administering to individuals in need of such treatment, thus effective amounts of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which includes at least one non-sulfurous mineral and/or thermal water, e.g., an extract derived from the bacterium Vitreoscilla filiformis, in particular the strain ATCC 15551, cultured in a medium enriched with water from La Roche Posay.
摘要:
Specific fractions of Vitreoscilla filiformis comprising its Lipid A are useful for stimulating the synthesis of anti-microbial peptides of the skin.

摘要:
The invention relates to a process for the preparation of a cosmetic or dermatological active principle, comprising the culturing of at least one nonphoto-synthetic and nonfruiting filamentous bacterium on a medium comprising at least one nonsulphurous mineral and/or thermal water. It also relates to a cosmetic or dermatological composition comprising at least one bacterium of the genus Vitreoscilla or one of its extracts.
摘要:
The invention provides a bioreactor (10) for the culture of animal, vegetable, microbial of algal cells of their co-cultures, of the type including a body (12) which delimits an internal volume (14) capable of holding a culture liquid (16) and a gas volume (17) above the culture liquid (16), and which includes means for introducing (18) and/or extracting (20) elements respectively into and/or out of the internal volume (14) of the body (12), and of the type which includes means (22) for driving the body (12) in an oscillating movement so as to obtain agitation of the culture liquid (16), characterised in that the body (12) is a rigid vessel.
摘要:
The present invention relates to a method for the preparation of a melanic pigment by enzymatic bioconversion, implementing a melanin precursor substrate and plant cells, characterized in that: (a) poppy (Papaver somniferum) plant cells previously cultivated are separated from their culture medium and subcultured in a culture medium with a concentration from 10 to 100 g/l; (b) the cells are ground at least partially, before or at the end of the latency time, (c) the at least partially ground cells are placed in a bioconversion medium in the presence with a melanin precursor substrate selected amoung indol, indolin, dihydroxyphenylalanin, tyramin and tyrosin; (d) the precipitated melanic pigment is collected. The invention also relates to the utilization of such resulting pigments for the preparation of cosmetic compositions.

Use of an extract of bacterium from the family Pseudomonadaceae in the production of cosmetic compositions in particular for combating ageing of the skin.
摘要:
Disagreeable/objectionable odors, notably body and sweat odors, are inhibited by treating the situs of same, for example the skin, hair and/or mucous membranes of a human subject, with hygienic/deodorant compositions comprising effective odor-/body odor-inhibiting amounts of at least one extract of undifferentiated plant cells.
