Table 5. Estimation of yield and maintenance coefficients of P. gingivalis and S. gordonii.

	Number of bacteria produced by 24h	Dry weight of bateria produced by 24h (gx)	Substrate consumed by 24h (gs)	Yield coefficient Yxs ($g_x{g}_s^{-1}$)
P. gingivalis	2.88 ⋅ 1010	5.39 ⋅ 10−4	3 ⋅ 10−3	0.18
S. gordonii	5.02 ⋅ 109	7.53 ⋅ 10−5	2 ⋅ 10−3	0.038
