Ancient Cheese DNA Unravels the Evolution of Probiotic Bacteria over Millennia
The groundbreaking discovery of ancient cheese DNA by scientists provides valuable insights into the evolution of probiotic bacteria over thousands of years. Chinese researchers have delved into the ancient human life in the Xinjiang region through their study of the world’s oldest cheese, dating back approximately 3,600 years.
An Unprecedented Study
Professor Qiaomei Fu from the Chinese Academy of Sciences in Beijing hailed this study as unprecedented, allowing researchers to observe how a bacterium evolved over millennia. The examination of dairy products has offered a clearer picture of ancient human life and their interactions with the environment.
Discovery and Significance
The cheese samples were discovered smeared on the heads and necks of Xiaohe cemetery mummies that date back to between 3,300 and 3,600 years ago in northwest China. The burial alongside mummies suggests that cheese may have been an important part of their lives or a significant element for their afterlife.
Identification as Kefir Cheese

Chinese scientists have recently made an extraordinary discovery in the field of archaeology and food science by successfully extracting DNA from the oldest cheese in the world. This groundbreaking research offers an unprecedented opportunity to unlock the secrets of ancient cheese-making techniques and provides valuable insights into the culinary history of mankind. In this article, we will delve into the details of this remarkable feat and explore the implications of this discovery.
Understanding the Significance of Ancient Cheese
Cheese has been a staple of human diet for thousands of years, with evidence of its existence dating back to ancient civilizations. The discovery of the oldest cheese in the world sheds light on the early practices of dairy farming and cheese-making, offering a glimpse into the culinary traditions of our ancestors. By analyzing the DNA extracted from this ancient cheese, scientists can gain valuable insights into the microbial communities, production techniques, and the regional variations in cheese-making during ancient times.
The Revelation of Ancient Cheese DNA Extraction
In a recent study published in the journal “Nature Communications,” a team of Chinese scientists reported their successful extraction of DNA from a piece of cheese dating back to over 3,200 years. The cheese sample was discovered in the Taklamakan Desert in China and is believed to have been made by the ancient people of the Tarim Basin. The researchers utilized advanced genomic sequencing techniques to analyze the microbial DNA present in the cheese, providing a rare glimpse into the microbial composition of ancient dairy products.
Implications of the Research Findings
The successful extraction of DNA from the ancient cheese opens up a wealth of opportunities for researchers and food historians to gain a deeper understanding of ancient cheese-making practices and its cultural significance. By studying the microbial DNA present in the cheese, scientists can uncover valuable information regarding the bacterial strains and yeasts used in ancient cheese production, as well as the environmental factors that influenced the fermentation process.
Additionally, this discovery offers an unprecedented opportunity to trace the origins and spread of dairy farming and cheese-making practices across different regions and civilizations. The genetic analysis of the ancient cheese DNA may provide insights into the migration patterns of early human populations and their interactions with local food resources, offering a holistic view of the cultural and
Previous beliefs about these substances as fermented dairy products were dispelled with new findings identifying them as a white kefir cheese. Cow and goat DNA were also found in these samples, indicating that different animal milks were used separately for making this ancient cheese.
Evolutionary Implications
Recovery of Lactobacillus kefiranofaciens bacteria DNA from these ancient dairy samples has provided an opportunity to compare it with modern strains used for making kefir. This comparison helps understand how present-day strains have evolved from those used thousands of years ago.
Challenging Long-Held Beliefs
This study challenges long-held beliefs about kefir originating solely in modern-day Russia, suggesting its presence since Bronze Age in northwestern China’s Xinjiang region. Additionally, it highlights how modern strains have evolved to be less likely to impact the body’s immune system compared to their ancient counterparts.
this breakthrough offers unparalleled insights into ancient cheesemaking practices and bacterial evolution while shedding light on human life in antiquity.
