FIG 2.

Phenotypic characteristics of the wild-type (WT) strain of C. hutchinsonii and the CHU_1277-disrupted mutant (Δ1277). (A) Growth curves of the cells in glucose and cellobiose medium. The closed and open symbols stand for growth of the cells in glucose and cellobiose, respectively. (B) Filter paper degradation and colony spreading of the bacterial cells on soft agar. Δ1277+pCH1277, the CHU_1277 mutant complemented with pCH1277; Δ1277+pCHP1277, the CHU_1277 mutant complemented with pCHP1277. Abs, absorbance.
