Microbiologist RESEARCH SCIENTIST expert ONLY.. not just a physician,
(please no experts like Rick, Phil, Thomas, etc. thanks)There is a shelf-stable product with an viable Lactobacillus, suspended in sunflower and coconut oil, with a long shelf life at room temp. Regarding bacterial stages, how does a bacteria (in this case anaerobic) survive this long in an undesired environment and without food source? And what does it take to become live and active again. e.g. let’s say you put this bacteria solution on your skin, what’s the ideal way to make it switch from that dormant shelf state, to a state of feeding and multiplying, (especially since it's anaerobic). And how do I determine if this strain can cause infection if enter through broken skin?

Lactobacilli are facultative anaerobes, not obligate anaerobes- If obligate anaerobes, they would die in the presence of O2-

It goes into a "dormant state" when preserved/ dried as in probiotic products- They do quality control tests, (for what it's worth- remember these are not FDA regulated so the level of quality control varies....) to assure a certain number of live colonies will be present per dose-

Lactobacilli then reactivate under the conditions in the human body- in the small intestine

The surface of skin would not be ideal for growth- which depends on moisture, temp, pH etc... Clinically however, we rarely do see some patients that get "bacteremic" with probiotic strains- the most classic example that has been reported in the literature is patients who have a G-tube ( a feeding tube through the skin) who are on probiotics and presumable some of the organisms colonize the skin when administered and then occasionally can lead to systemic infectiions- but this is uncommon of course..

Please rate the reply if that answered your question

Hi, thanks for the info. I didn't yet see the answer.
"And what does it take to become live and active again. e.g. let’s say you put this bacteria solution on your skin, what’s the ideal way to make it switch from that dormant shelf state, to a state of feeding and multiplying, (especially since it's anaerobic)."
So how do I take that dormant Lactobacilli and activate it to live on the skin? What specific solution providing a certain moisture, pH, food, etc? What is the Lactobacilli preferred temp range for growth? or does it depend greatly on the strain?
Doctor: TheGermDoctor, Doctor replied 1 year ago

Probiotic lactobacilli are not prepared for cutaneous use, and there is no rationale for such usage- There are GI and vaginal preps, not cutaneous- with conditions comparable to the GI tract or vaginal mucosa appropriate for usage.

I would not advise topical use of lactobacilli and can think of no therapeutic usage for such

that's the conclusion I came to and so I thought to come on JustAnswer in order to ask the ideal prep for cutaneous delivery of lactobacilli.

Hello,

I'm another expert as per your request

Dr Chaithanya here, Medical researcher as well

Lactobacillus are given for treatment of few skin conditions as well, like eczema, acne, atopic dermatitis. Recent researches prove this

They are given as per oral even for the treatment of skin conditions.

They are nutritionally fastidious, requiring rich media to grow (carbohydrates, amino acids, peptides, fatty acid esters, salts, nucleic acid derivatives, and vitamins

Please study this link,

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2593565/

This is so extensive, and clear, that you will not be left with any doubts further about Lactobacillus

Hope this helps

Have a good day
