Biomarkers of bacterial spore germination
WebOct 9, 2024 · The NSAF of all the proteins previously considered as biomarkers was calculated and expressed in percentage. The ratio of spores in the samples was calculated for each sample based on the ratio of NSAF of spores versus NSAF of spore and vegetative cell biomarkers (Table 2 ). The ratios are equal to 0.646 and 0.649. WebMay 2, 2024 · Coming out of bacterial hibernation with germination. The remarkable revival process initiates with a key event, termed germination.
