Figure 4
Effect of the palA1 mutation on extracellular α-L-rhamnosidase activity produced by xlnB p ::rhaA, gpdA p ::xlnR strains. Bar diagram of the α-L-rhamnosidase activities in AR207 and AR208 (xlnBp::rhaA, gpdAp::xlnR, palA1) and AR206 (xlnBp::rhaA, gpdAp::xlnR) strains. Supernatants of the indicated strains were obtained after grown in 1% w/v OSX pH 5.5 at the time indicated. Values (mU ml−1) are presented as means ± SD. For each strain, at least two independent cultures were carried out.
