FIG. 1.

Bio-Gel P-4 elution profile of OPGs of E. chrysanthemi grown in LOS medium (●) or in LOS medium supplemented with 0.3 M NaCl (■). The column (1.6 by 55 cm) was eluted with 0.5% acetic acid, and aliquots were analyzed for total carbohydrates (see Materials and Methods). Results are expressed as glucose equivalents per milliliter of eluant. In both cases, fractions indicated by the horizontal bar were lyophilized.
