Figure 1. Comparison of flocculation ability by ETH-2 and PAM for wine process wastewater.

Figure 1

Three hundred µl ETH-2 strain culture broth (OD600 = 1.8) and 0.1% PAM were added into 5 ml wine process wastewater (COD: 4299.0 mg/L; pH = 4.0; SS = 315.0 mg/L), respectively. The cylinder was gently shaken, settled at room temperature for 5 min, and measured the OD550.
