Functional Group Distribution of the Carrier Surface Influences Adhesion of Methanothermobacter thermautotrophicus

Figure 6

Correlation between -OH and -COOH functional groups on the surface of the carrier (treated with NaOH, HCl, H2SO4, or Na2HPO4) wherein quantity of adhesion of methanogen improved. The correlation was determined by linear regression: , where of -OH and of -COOH; is the coefficient of determination.
