  1. a Strains were cultured in XVM2 liquid medium supplemented with various carbon sources. Data presented are means and standard errors of three replicates from one representative experiment and similar results were obtained in two other independent experiments. Different letters in each data column indicate significant differences at P < 0.05 (Student's t-test).
