An antimicrobial agent can be defined as any compound, natural or synthetic, that can slow/inhibit microbial growth and/or kill and reduce microbial populations when used in food processing. From: Handbook of Natural Antimicrobials for Food Safety and Quality, 2015 ...
Long-term persistence, facilitated by dormancy, is critical in order for desert microorganisms to survive extended droughts and thus remain members of the microbial community15,16. However, dormancy mechanisms of desert soil microorganisms remain elusive, as information on desiccation survival strategies i...
This is the same relationship between TSD, inoculum size, and growth rate as for the simple birth process with exact inoculation, Eq. (11b). Age-structured population growth Organismal division is carefully choreographed, and we next turn to models that resolve some of the structure of individual...
Different methods to determine the "lag time" often yield different values, demonstrating that it is a poorly defined growth parameter. The combined effect of several factors, such as temperature and pH or aw, need not be "multiplicative" and therefore ought to be revealed experimentally. This ...
1c, d). The remaining fractions did not significantly affect the growth of the cells as compared to the respective control (Supplementary Fig. 1b, c). The results suggested that the cytostatic effect could be attributed to compounds present in the F > 50 kDa fraction, such as proteins...

General speaking, which can inhibit the growth of microbial reproduction or kill microbes, and slow food decaying chemical or biological metabolism, are referred to as a preservative. A.错误 B.正确 点击查看答案
Fig. 1: Microbiome data is represented by relative abundances, thus differential abundance analysis should account for the bias introduced by across-sample variations in sampling fractions. Sampling fraction is defined as the ratio of expected abundance in a sample to the corresponding absolute abundance...
is low, the fragmented spectrum may lack ions that are present in spectra obtained from high-intensity precursor ions. This may result in ‘data leakage’ as the MS/MS spectrum may be missing ions, leading to the two molecules not being recognized as the same molecule. To partially overcome...
