Table 1. The effect of the different carbon sources on C. indologenes MUT.2 growth and extracellular polymeric substance (EPS) production during cultivation in the shake-flasks for 96 h at 30ºC. The highest cell mass, EPS and other related factors were observed when sucrose was used a carbon source .
