Fig. 4. Analysis and identification of crude extraction results of antibacterial substances. (a) Standard curve of protein concentrations; (b) Effect of pH on the biaqueous extraction of bacteriocins produced by strain 1; (c) Effect of pH on extraction of bacteriostatic protein from strain 24; (d) Tricine-sodium dodecylsulphate-polyacrylamide gel electrophoresis (SDS-PAGE) of antibacterial proteins extracted using the two-phase method. A 562: absorbance at 562 nm; M: marker; 1: strain 1; 2: strain 24.
