This model is developed by Zwietering et al. (1992, 1993).It's a square root type model but with an extra ﬁtting parameter-c2

1	modZwite(pH, pHmin, pHmax, pHopt, muopt, c2)

`pH`	pH # a number
`pHmin`	Minimal growth pH #a number
`pHmax`	Maximal growth pH #a number
`pHopt`	Optimal growth pH #a number
`muopt`	Optimal growth rate # a number
`c2`	a parameter # a number

\begin{equation}γ_{\mathrm{pH}}=≤ft[\frac{≤ft(\mathrm{pH}-\mathrm{pH}_{\min }\right)≤ft(1-\exp ≤ft\{\mathrm{c}_{2}≤ft(\mathrm{pH}-\mathrm{pH}_{\max }\right)\right\}\right)}{≤ft(\mathrm{pH}_{\mathrm{opt}}-\mathrm{pH}_{\min }\right)≤ft(1-\exp ≤ft\{\mathrm{c}_{2}≤ft(\mathrm{pH}_{\mathrm{opt}}-\mathrm{pH}_{\max }\right)\right\}\right)}\right]^{2}\end{equation}

mumax #maximum growth rate # a number
