Effect of the watR gene overexpression on LA tolerance. a The indicated overexpression cassette OE1, OE2, or OE3 was integrated into the genome of wild-type Methylomonas sp. DH-1 (WT) and mRNA levels of the overexpressed genes were detected by qRT-PCR. b LA tolerance was examined by growing the cells in the absence (Control) or presence of 0.6 g/L LA. Error bars indicate standard deviations of three independent experiments
