Item Producción y eficacia de proteínas antioxidantes derivadas de hongos en comparación con las obtenidas de bacterias: Una revisión sistemática(Universidad Santiago de Cali, 2025-12-11) Bastidas Jaramillo, Derly JuriedOxidative stress is a key factor in the onset of chronic and degenerative diseases, which has driven interest in safe and sustainable natural antioxidants. Microorganisms, especially bacteria and fungi, have emerged as valuable sources of proteins with antioxidant activity and high biotechnological potential. This systematic review analyzed studies published between 2015 and 2025 to compare the production, mechanisms of action, and efficacy of antioxidant proteins derived from fungi versus those obtained from bacteria. The results show that the bacteria produce highly stable enzymes under pH variations between 2-10 and temperatures from 5°C to 80°C, while fungi exhibit a greater diversity of isoforms and metabolites with antioxidant and antimicrobial activity. Optimization of culture media, the use of agroindustrial residues, and genetic engineering were identified as effective strategies to enhance the yield and stability of these biomolecules. In conclusion, microbial antioxidant proteins represent a promising alternative to synthetic compounds, with relevant applications in the food, pharmaceutical, cosmetic, and environmental industries, contributing to the development of more sustainable and innovative processes.
