Lactobacillus acidophilus Fermented Milk – A Very Effective Antifungal?
The milk fermented with Lactobacillus acidophilus bacteria is not a kefir. Kefir is produced also by fermentation but using the different species of bacteria.
Lactobacillus acidophilus is a popular specie of probiotic bacteria used in almost every bacterial probiotics you can buy in a health food store.
Moreover it is used to produce many different fermented foods including the plain yogurt and fermented milk which are very popular foods in many countries in the world.
The two Petri dishes were filled with 4 ml of Lactobacillus acidophilus fermented cow’s milk (bought in a grocery store) and covered with the lid immediately.
The only difference in second Petri dish is that I put a drop of Cassia essential oil right in the center of Petri dish. Then I intentionally made the drop of Cassia oil flow near the border of Petri dish.
I did so in order to better demonstrate the (possible) antifungal effects of Cassia oil.
However, as this test proved there is enough of antifungal effects in Lactobacillus acidophilus fermented milk on its own.
Neither one of the Petri dishes had any sign of mold growth after 14 days.
The next pictures were taken 8 days into the test when Petri dishes were at room temperature (23°C/73°F).
The biggest weakness of this test is the number of samples – only 2 Petri dishes – and one of them had also strong antifungal Cassia oil in it.
On the other hand, we all know how versatile the fungus is. It will grow literally everywhere where there is no strong antifungal compound present.
It can grow on walls and even on the plastic covers of electrical outlets where there is not so much “to eat” and still can grow on those surfaces.
Fungi and yeasts thrive on starches and sugars. So fermented foods like Lactobacillus acidophilus milk with fat which has naturally low amount of sugar (lactose is fermented by bacteria) – is not the most preferred food for fungi.
Another fact is that bacteria including Lactobacillus acidophilus produce different chemical compounds (like lactic acid) which help them compete with other bacteria and fungi.
I would say that Lactobacillus acidophilus fermented milk is a good antifungal food for those who can eat dairy products without negative effects like increased inflammation.
