Minas Gerais University Establishes Seed Bank to Preserve Artisanal Cheese Microbial DNA
The Federal University of Lavras (UFLA) in Minas Gerais, Brazil, has launched an innovative microbial bank to safeguard the unique 'DNA' of artisanal raw milk cheeses. This initiative aims to preserve the microbial biodiversity responsible for the distinct flavors, aromas, and textures of these cheeses, which are considered a significant food and cultural heritage of the state. The project, housed at the Microbiological Resources Unit (URmicro), will store cheese samples from various regions of Minas Gerais for decades. Researchers refer to this as preserving the 'microbiological signature' of each cheese, encompassing the bacteria, fungi, and yeasts that contribute to its identity and potential health benefits. The creation of this bank addresses the urgent need to protect this biodiversity against the impacts of climate change and to support the growing appreciation for traditional Minas Gerais artisanal cheese. Professor Luís Roberto Batista, the project coordinator, emphasized that preserving these microorganisms is crucial for maintaining the authenticity and identity of the cheeses, as environmental factors can alter their composition over time. Unlike conventional microbial banks, UFLA's approach involves preserving portions of the actual cheese. This method was chosen because isolating and conserving every microorganism present in artisanal cheese is not yet fully feasible. Samples are collected from cheeses at different stages of maturation, from fresh to 60 days old. A small portion is then preserved in a cryoprotective solution and stored in ultrafreezers at -80°C, ensuring the microbiological characteristics remain intact for decades. This storage service will be provided to producers at no cost. The bank currently has the capacity to store approximately 20,000 samples, with plans for expansion. The university intends to collect samples from the same producers over multiple years to track the evolution of the cheeses and their microbial communities.
This initiative by UFLA represents a forward-thinking approach to cultural heritage preservation, leveraging scientific methods to protect a vital component of artisanal food production. By establishing a microbial bank for artisanal cheeses, the university is creating a system to mitigate risks associated with environmental changes and market pressures that could otherwise erode the unique characteristics of these products. This proactive measure acknowledges the intrinsic value of traditional foodways and seeks to provide a scientific foundation for their continued authenticity and safety. The project's focus on preserving the 'microbiological signature' highlights the complex interplay between environment, production methods, and sensory outcomes, offering a model for other agricultural heritage sectors. In an era where industrialization often homogenizes food production, such initiatives are critical for maintaining regional diversity and supporting small-scale producers.
