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.
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 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:
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:
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.
