TABLE 1.

Growth rates of shaken batch cultures of M. dichloromethanicum DM4 and its polA derivatives with different carbon sources^a

Strain	Growth rate (h−1) on carbon source
	MeOH	DCM	MeOH-DCM	MeOH-CH2O
DM4 wild-type	0.19	0.08	0.12	0.19
DM4-1445	0.17	—b	0.08	0.17
DM4-1445(pME8112)	0.17	0.08	0.11	0.19

^aThe concentration of MeOH was 40 mM, that of DCM was 10 mM, and that of formaldehyde (CH₂O) was 1 mM. Standard errors are <0.01 h⁻¹ in all cases. 

^b—, no growth.
