** Rinker et Kelly [23]. This value of \(m_{\text{GLU}}\) was obtained for T. maritima culture in chemostat
^a \(Y_{{{\text{X}}/{\text{GLU}}}}\) used for the mathematical model was of 20.9 g/mol. This value was obtained by subtracting the quantity of glucose used for the maintenance. The following values were used: \(Y_{{{\text{X}}/{\text{GLU}}}}\) = 20.4 g/mol, \(m_{\text{GLU}}\) = 2.2 mmol/g/h and μ = μ _max = 0.9 h⁻¹
