Virtually 50% of the whey produced by the cheese trade is discharged into water our bodies, inflicting air pollution and ecological imbalances. In Mexico, it’s reported that in areas comparable to Veracruz and Chiapas, greater than 100,000 liters of whey are dumped day by day into rivers, altering their composition and affecting biodiversity.
Scientists from Tecnológico de Monterrey and the Technical College of Denmark (DTU) are utilizing communities of yeasts and micro organism to rework this waste into high-value protein utilizing an modern precision fermentation course of to interrupt down the lactose in whey and remodel it into protein-rich biomass. There isn’t any genetic modification used within the course of.
“Using microbial communities is vital on this course of,” stated Dr. Mario Antonio Torres Acosta of Tecnológico de Monterrey and lead for this challenge.
“In nature, microorganisms don’t perform in isolation however in consortia the place they complement one another. We leverage this precept to optimize the conversion of waste right into a product with excessive added worth.”
Dr. Torres-Acosta instructed NutraIngredients that the analysis workforce has demonstrated that utilizing combined microbial communities ends in elevated protein yields in comparison with the usage of single microorganisms.
One other key purpose is to strategy firms to reveal their capabilities and discover potential partnerships or collaborations to proceed or prolong or exploit this challenge, he stated.
“We’ve noticed that the manufacturing of different proteins is now not an choice however a necessity. We face an unprecedented local weather and meals safety disaster, and growing sustainable protein sources might be key to feeding a rising inhabitants”

Single-cell protein (SCP): Nutritious, sustainable and inexpensive
Dr. Torres-Acosta stated that the principle goal of Single-Cell Protein is to exchange animal-based protein (i.e., meat), whereas the aim of utilizing whey is to scale back the quantity of whey that’s discarded to water our bodies and forestall/scale back environmental issues.
He added that whey, by itself, is a really nutritious product, however the whey-based protein merchandise for sports activities or muscle era are usually not solely whey however are whey protein plus different elements.
“Using whey as a substrate for yeast fermentation generates a pure full distribution of important amino acids, minerals and nutritional vitamins that aren’t current naturally in whey,” he stated.
The Single-Cell Protein dietary profile varies relying on the totally different microorganisms used (Saccharomyces cerevisiae versus Kluyveromyces marxianus or Yarrowia lipolytica, for instance).
“One of many key benefits of utilizing SCP is that some microorganisms generate key nutritional vitamins, comparable to B12,” Dr. Torres-Acosta stated. “Plant-based proteins lack B12, which is required for human vitamin. Additionally, microorganisms like S. cerevisiae generate all important amino acids. Lastly, relying on the substrate used, the microorganisms can generate totally different fragrant compounds that may enhance organoleptic properties of ultimate merchandise.”
Advantages
In keeping with the researchers, the single-cell protein (SCP) various affords a number of benefits in comparison with conventional protein sources:
– Superior vitamin: Being wealthy in important amino acids, it may be extremely digestible and have a organic worth corresponding to that of meat and milk.
– Decrease environmental affect: Its manufacturing generates fewer carbon emissions and requires much less water and land, particularly when in comparison with conventional livestock farming.
– Aggressive value: Whereas SCP might be produced for $1,600 per ton, its market value might vary between $5,000 and $7,000 per ton, considerably decrease than, for instance, beef ($10,000 per ton).
– Good market acceptance: Not like proteins derived from microalgae, which are inclined to have a robust taste and an unappealing colour, yeast-based SCP has a extra impartial organoleptic profile, making it adaptable to totally different meals functions most well-liked by new generations of customers.
“The mixture of biotechnology, computational modeling, and precision fermentation permits us to design an environment friendly, scalable and economically viable course of for single-cell protein manufacturing.”
