differences were demonstrated in the molecular mass distribution
(Fig. 4). Even though the major EPS fraction (peak I) in CDMGal had
the highest molecular mass, EPS in CDMGal showed the lowest vis-
cosity. A low molecular mass fraction (peak III) could be found only
in the EPS from MRS indicating that differences in EPS chain length
are unlikely to cause variations in viscosity. In Lactobacillus
rhamnosus R lowering molecular mass of EPS caused a decline of
the viscosity of EPS solution (Pham et al., 2000). Therefore, the vis-
cosity of EPS solution might be affected by the ratio of low molec-
ular mass EPS. A certain relationship between viscosity and
molecular mass distribution of EPS has been observed in peak II
(Fig. 4). Degradation of peak II fraction may cause the lower viscos-
ity of EPS released in CDMGal and CDMSuc. It was difficult to find a
clear relationship between molecular mass distribution and viscos-
ity; nevertheless, heterogeneity of molecular mass distribution
was the most probable cause for the variation of EPS viscosity.

4. Conclusions

affecting exocellular polysaccharide production by Lactobacillus delbrueckii
To conclude, a CDM for L. fermentum TDS030603 has been
developed. The ability of the strain to produce a highly viscous
EPS was observed in the CDM as well as in MRS. The production
of the EPS reaches the maximal concentration at the beginning of
the stationary phase, but degradation of the EPS was observed dur-
ing 72 h cultivation. Carbohydrates did not affect the chemical
structure of the EPS, but did affect the production yields. Moreover,
the viscosity of the EPS was also affected by carbohydrates, possi-
bly owing to the heterogeneity in the molecular mass distribution
of the EPS.
