Doubling times of UA159, glmS or nagB deletion mutant and its complement strains grown in TSB or CDM-G50.

1Doubling time (DT) was calculated based on the formulas ln Z – ln Z0 = k (t – t0), where k is the growth rate, and g = 0.693/k×60, where g is the doubling time (min). Values are the mean ± standard deviation obtained from three independent experiments.1. 倍增时间（Doubling Time，DT）基于如下公式计算：lnZ – lnZ₀ = k(t – t₀)，其中k为生长速率；另有公式g = 0.693/k × 60，式中g为倍增时间，单位为分钟（min）。所得数值以平均值±标准偏差的形式呈现，均来自三次独立重复实验。
