Microbial Oxidative Stress in Food Fermentations: A Comprehensive Review

eFood, Volume 7, Issue 4, August 2026.
Oxidative stress has a dual role in food fermentations: low ROS supports adaptive signaling, whereas excessive ROS causes cellular damage and process inhibition. Managing redox state as a controllable process variable can improve fermentation robustness and final food quality.

Elucidating the physiological significance of iodate reduction in Shewanella species

mLife, Volume 5, Issue 4, Page 507-519, August 2026.
Abstract The reduction of iodate by Shewanella species plays a crucial role in iodine biogeochemical cycling. However, the physiological significance of this reduction process remains poorly understood, because Shewanella species are capable of reducing only low concentrations of iodate.
