Microorganisms Inhibiting the Formation of Axillary Malodor
Described are microorganisms which are able to suppress the production of malodorous compounds by axillary bacteria. Also described are compositions comprising such microorganisms as well as the use of such microorganisms in cosmetic, prophylactic or therapeutic applications.
1 . A microorganism that is able to suppress the release of 3-methyl-2-hexenoic acid or an odorous derivative by axillary bacteria.
2 . The microorganism of claim 1 that is able to suppress the release of 3-methyl-2-hexenoic acid or its odorous derivatives by axillary bacteria in at least one of Assays A, B or C as follows:
Assay (A):
(i) mixing the microorganism with a microorganism that is capable of releasing 3-methyl-2-hexenoic acid or an odorous derivative thereof and with an odorless axillary secret;
(ii) incubating the mixture under conditions allowing the release of 3-methyl-2-hexenoic acid;
(iii) extracting short fatty acids from the supernatant of the mixture; and
(iv) detecting odor release by the occurrence of 3-methyl-2-hexenoic acid;
or
Assay (B):
(i) mixing the microorganism with a microorganism that is capable of releasing 3-methyl-2-hexenoic acid or an odorous derivative thereof and with N-α-lauryl-glutamine;
(ii) incubating the mixture under conditions allowing the release of laureate derived from N-α-lauryl-glutamine; and
(iii) analyzing the supernatant of the mixture for the presence of N-α-lauryl-glutamine;
or
Assay (C):
a sniffing assay with the nose.
3 . The microorganism of claim 1 , wherein the 3-methyl-2-hexenoic acid or the odorous derivative is released by a bacterium of the genus Corynebacterium.
4 . The microorganism of claim 3 , wherein the bacterium is Corynebacterium jeikeium.
5 . The microorganism of claim 1 , wherein the bacterium belongs to the genus Lactobacillus.
6 . The microorganism of claim 5 , wherein the Lactobacillus is Lactobacillus plantarum, Lactobacillus crispatus, Lactobacillus acidophilus II, Lactobacillus acidophilus III or Lactobacillus delbrückii delbrückii.
7 . The microorganism of claim 6 selected from the group consisting of Lactobacillus plantarum OB-AG-0002 (DSM 17598), Lactobacillus crispatus OB-AG-0003 (DSM 17567), Lactobacillus acidophilus II OB-AG-0004 (DSM 17568), Lactobacillus acidophilus II OB-AG-0005 (DSM 17569), Lactobacillus acidophilus III OB-AG-0006 (DSM 17570), Lactobacillus delbrückii delbrückii OB-AG-0007 (DSM 17571), a mutant thereof and a derivative thereof, wherein the mutant or the derivative retains the ability to suppress the release of 3-methyl-2-hexenoic acid or its odorous derivatives by axillary bacteria.
8 . The microorganism of claim 1 , wherein the microorganism is an inactive form and able to suppress the release of 3-methyl-2-hexenoic acid or its odorous derivatives by axillary bacteria.
9 . The microorganism of claim 8 that further is thermally inactivated or lyophilized.
10 . A composition comprising a microorganism selected from the group consisting of the microorganism of claim 1 , wherein the microorganism optionally further is an inactive form and wherein the optionally inactive form optionally is further thermally inactivated or lyophilized.
11 . The composition of claim 10 which is a cosmetic composition optionally comprising a cosmetically acceptable carrier or excipient.
12 . The composition of claim 10 which is a pharmaceutical composition optionally comprising a pharmaceutically acceptable carrier or excipient.
13 . A method for the production of a cosmetic composition comprising the step of formulating the microorganism of claim 16 with a cosmetically acceptable carrier or excipient.
14 . The method of claim 13 , wherein the microorganism belongs to the genus Lactobacillus.
15 . The method of claim 14 , wherein the Lactobacillus is Lactobacillus plantarum, Lactobacillus crispatus, Lactobacillus acidophilus II, Lactobacillus acidophilus III or Lactobacillus delbrückii delbrückii.
16 . The method of claim 14 , wherein the microorganism is selected from the group consisting of Lactobacillus plantarum OB-AG-0002 (DSM 17598), Lactobacillus crispatus OB-AG-0003 (DSM 17567), Lactobacillus acidophilus II OB-AG-0004 (DSM 17568), Lactobacillus acidophilus II OB-AG-0005 (DSM 17569), Lactobacillus acidophilus III OB-AG-0006 (DSM 17570), Lactobacillus delbrückii delbrückii OB-AG-0007 (DSM 17571), a mutant thereof and a derivative thereof, wherein the mutant or the derivative retains the ability to suppress the release of 3-methyl-2-hexenoic acid or its odorous derivatives by axillary bacteria.
17 . The method of claim 13 , wherein the microorganism is an inactive form and retains the ability to suppress the release of 3-methyl-2-hexenoic acid or its odorous derivatives by axillary bacteria.
18 . A method for the production of a pharmaceutical composition comprising the step of formulating the microorganism of the microorganism of claim 16 with a pharmaceutically acceptable carrier or excipient.
19 . The method of claim 18 , wherein the microorganism belongs to the genus Lactobacillus.
20 . The method of claim 18 , wherein the microorganism is an inactive form and retains the ability to suppress the release of 3-methyl-2-hexenoic acid or its odorous derivatives by axillary bacteria.
