Keywords:microorganisms present in the food industrySummary:Industrial Microbiology: At CNTA we continuously maintain and incorporate new strains into our collection of lactic bacteria, yeasts and fungi isolated from various sources, mostly food, capable of providing various nutritional and technological functionalities (antifungal, texturizing, antibacterial, antioxidants...) through its metabolic control. The optimization of fermentative processes is another area of research that allows the development of methodologies to improve yields and directed metabolism during microbial growth.New Conservation Strategies and Technologies: We work on the development and application of physical, thermal and non-thermal conservation technologies, such as high hydrostatic pressure, high pressure in combination with temperature, radiofrequency, high voltage electrical pulses, high power ultrasound and cold plasma, as well as research into new strategies based on chemical agents such as the use of protective cultures, bioactive peptides or natural preservatives.

Brief historical review
The CNTA collection is 15 years old. It is a relatively young collection. Many of the strains come from research projects developed under contract by partner companies or customers of CNTA and their use is restricted (partially or totally). Others come from public projects and the property belongs to CNTA.
