Cellulose biosynthesis and complex macrocolony morphology after chromosomal “repair” of the SNP that generates a stop codon early in bcsQ in E. coli K-12 strain W3110. (A) Operon structure of the bcs region and position of the TAG/TTG SNP in bcsQ. (B) Macrocolony structure of strain AR3110, a W3110 derivative with the bcsQ(TTG) allele after growth on salt-free LB plates for 5 days. (C) Fluorescence of 1-day-old colonies grown on Calcofluor plates of strain AR3110 and its indicated mutant derivates and strain W3110. (D) Colony morphology of AR3110 and the indicated mutant derivates after growth on CR plates for 5 days.
