Addition of an Euglena extract to milk in a test tube, followed by incubation at a constant temperature, facilitated milk solidification into yogurt. Furthermore, pH monitoring showed that acidification of milk was accelerated by the addition of the Euglena extract. These results suggest that the addition of Euglena extract facilitates the production of lactic acid by lactic acid bacteria.
As many as 100 trillion of bacteria, belonging to more than 100 different species, are considered to inhabit human intestines. Maintaining the dominance of beneficial bacteria such as lactic acid bacteria and bifidobacteria in the gut flora is essential to keep the body healthy.
