Streptococcus thermophilus


Streptococcus thermophilus is a Gram-positive bacterium which is also classified as a lactic acid bacterium. It is often found in fermented milk products such as yoghurt, cheeses and milk drinks. It is just one of the many beneficial bacteria that is added to food and drinks to enhance a person’s immune system functions and to help keep a healthy colon too.

The ability of Streptococcus thermophilus to survive is simple, it has a thick cell wall that can help survive in extreme temperatures. Dairy products are heated for processing up to 100 degrees Celsius and these bacteria can withstand these extremes in temperature very well.

History and Origin

The name Streptococcus is derived from the Greek word which means “twisted berry” it is seen under the microscope as a chain that resemble a string of beads. Thermophilus is a Greek term which means heat, referring to an organism that is able to survive extreme cases of heat.

Ancient Uses

The use of beneficial bacteria like Streptococcus thermophilus for disease prevention and for keeping a healthy colon was not heard of during the ancient times. Ancient cultures mainly ate well to keep healthy. Gastrointestinal illnesses were treated with herbal remedies; stomach pain, intestinal parasites, diarrhea, constipation, etc, are the most common illnesses that used herbal treatments.

Modern Uses

In modern times, the use of Streptococcus thermophilus is to fight the spread of harmful bacteria in the gut. This method is called Probiotics treatment. Live strains of Streptococcus thermophilus and other good bacteria are placed in milk products such as yoghurt and milk based drinks to fight bad bacteria, yeast, fungus and toxins in the body.
