C. acutatum	$f\left(x\right)=-0.9005e^{-{((x-12.59)/530.2)}^2}$	0.9835	0.7591	f(x) = (1.01x 2+302.7x)10−4+2.615	0.941
R. stoloifenr	$f\left(x\right)=-0.9e^{-{(\left(x-12.59\right)/464.7)}^2}$	0.9927	0.7382	F(x) = (2.9x 2+22x)10−4+3.13	0.983

*R_c ² and R_p ² were the coefficient of determination of calibration and prediction, respectively; r, the correlation coefficient of prediction accuracy between spectral values and colony forming unit.
