How to prepare the lactic acid bacteria serum. It is an effective defense against fungi and viruses.

People looking for health-related information will most likely encounter the term "lactic acid bacteria". Lactic acid bacteria are a group of related bacteria that produce lactic acid as a result of carbohydrate fermentation. These beneficial microorganisms are always associated with health foods, skin care as well as healthy living. Lactic acid bacteria are often found in animal oral cavities and intestines, as well as decaying plant or animal material.

Health or Nutritional Benefits of Lactic Acid Bacteria

Some species of lactic acid bacteria have health or nutritional benefits. Among those benefits are the following:

1. Improved nutritional value of food.

2. Control of intestinal infections. Lactic acid bacteria can control intestinal infections. 

3. Improved digestion of lactose.

4. Control of some types of cancer.

5. Control of serum cholesterol levels.

How To Prepare Lactic Acid Bacteria Serum


Rice wash

2 clay jars


Clean sheet of paper and string

Fresh milk

Crude sugar


1. Drain the first rice wash into a clay jar. This has plenty of good microorganisms. The accumulated rice wash should be seven inches deep.

2. Cover the clay jar with a clean sheet of paper and tie the mouth firmly with a string. Place it in a cool and shaded place.


3. After seven days, the rice bran will float on top. Strain and place the water into a separate clay jar. 

4. Add fresh milk into the strained water in the new jar. This should be 10 times the quantity of the water.

5. Cover the mouth of the jar with a clean sheet of paper and tie firmly with a string. After seven days, the fat will float on top and underneath it is a yellowish substance. This is the lactic acid serum (LAS).

6. Extract only the yellowish substance using a hand pump.

7. Add crude sugar (the same amount with the LAS). This will prevent spoiling and store in a cool and shaded place for seven days.

How to Use the Serum

Mix two tablespoons of LAS to one liter of water. This can be used as animal drink as well as sprinkled to plants and compost. It will serve as a good defense against fungi and viruses.
