The growth rate constants for the no cellulose strain, k = 1.26 ± 0.037 (SE) h −1 , the wild-type strain, k = 1.41 ± 0.040 (SE) h −1 , and the increased cellulose strain, k = 1.35 ± 0.019 (SE) h −1 , are similar, with only a slightly significant difference between the no cellulose and wild-type strains ( p = 0.047).
