Researchers conducted a study on three types of dates: Mazafati, Pyaram and Zahedi, and stated that dates can be a source of probiotic bacteria.
Probiotics; They are living microorganisms that, if consumed in sufficient quantities, cause health. The beneficial effects of probiotic bacteria on human and animal health have been extensively studied and confirmed in various cases.
Probiotics can be extracted from a variety of sources such as dairy and fruits. Preliminary studies suggest that dates can be an important nutrient for the acquisition of probiotic bacteria “Bacillus” and “lactic acid”.
Accordingly, researchers conducted a study on the possibility of extracting probiotic bacteria lactic acid and bacillus from the aqueous extract of three types of dates “Mazafati”, “Pyaram” and “Zahedi”.
For this study, aqueous date extract was extracted in the laboratory and then the extracted extracts were transferred to culture media to isolate the bacteria. After five days of culture, bacterial colonies or assemblages were observed to form in the culture medium. By microscopic examination, the colonies, which were similar in appearance to the bacteria in question, were isolated and subjected to more detailed biochemical and molecular studies.
The observations of these experiments showed that the bacteria isolated from Mazafati date extract belonged to Lukonostoc mesentroid family, the bacteria isolated from Pyaram date belonged to Bacillus subtelis family and the bacteria isolated from Zahedi date belonged to Esro family. Evaluations showed that all three types of bacteria had probiotic properties.
The researchers of this study say according to the obtained results: The studies show that dates are in the collection of probiotic foods and the aqueous extract of dates can be used to enrich and prepare probiotic foods.
According to these researchers; Due to the properties of probiotic bacteria, aqueous extract of dates or date meat can be recommended to prevent diseases.
In conducting this research, Mina Seifzadeh and Mohammad Rabbani; Researchers from the Department of Biology, University of Isfahan, and Ali Asghar Khanipour from the Bandar Anzali Aquatic Aquaculture Research Institute participated together.
The findings of this study were published in the summer of this year as a scientific article entitled “Identification of probiotic bacteria in aqueous extracts of Mazafati, Pyaram and Zahedi dates” in the Journal of Cellular and Molecular Research (Iranian Biology).
