At a known concentration of organic carbon, the temperature correction coefficient (Θ), derived from Eq. 3, allows for prediction of biofilm productivity at any temperature within the range evaluated, i.e. 7–27 ° C. At a given water temperature and concentration of organic carbon, the Θ-values from Table 3 can be applied to the equation4\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ {K}_{prediction}=5.152*{\theta}^{T_{water}-280} $$\end{document}Kprediction=5.152*θTwater−280to predict algal biofilm productivity. A larger Θ value indicates a more significant increase in growth rate as temperature increases.
