chilean Hot Springs Yield Promising Natural additive for Food and Pharmaceutical Industries
A groundbreaking study has unveiled a novel exopolysaccharide (EPS) produced by Pseudomonas alcaligenes Med1, a bacterium isolated from the Medano hot spring in Chile’s Andean Mountains. This discovery, published in Scientific Reports, highlights the potential of extremophilic bacteria to revolutionize industries by offering sustainable, natural alternatives to synthetic additives.
The research, a collaborative effort between Brazilian, chilean, American, and Iraqi scientists, was supported by the food Research Center (FoRC) and Chile’s National Fund for Scientific and Technological Advancement (Fondecyt). The study focused on isolating the bacterium, sequencing its genome, and optimizing EPS production under high temperatures to confirm its thermotolerance.
A Thermophilic Marvel
The isolated strain of P. alcaligenes Med1 demonstrated remarkable resilience, tolerating temperatures up to 44 °C, with an optimal growth temperature of 37 °C. This thermotolerance is a significant advantage, as it prevents the growth of unwanted microorganisms during EPS production.“The study concluded that the EPS produced by P. alcaligenes Med1 has unique structural properties and thermal stability,and also exhibiting significant antioxidant,emulsification,and flocculation activity,making it suitable for potential applications by the food and pharmaceutical industries as a natural additive,” said Fabi,one of the lead researchers.
Unique Properties and Applications
The EPS’s structural data, obtained through genome sequencing and analytical studies, revealed its potential as a natural choice to synthetic additives. Its thermal stability and biocompatibility make it particularly suitable for applications requiring high-temperature resistance.
According to Fabi, “Although more tests and regulatory approvals are needed for commercial use, this EPS displays strong potential as a natural alternative to synthetic additives, especially in applications that require thermal stability and biocompatibility.”
the study also provides a model for optimizing EPS production and offers new insights into the bioactivity of this compound. These findings could pave the way for the development of eco-friendly additives for the food, cosmetics, and pharmaceutical industries.
A Model for Future Research
The exclusive structural data obtained in this study opens the door for exploring other extremophilic bacterial EPSs with similar applications.
