Figure 3. Endochitinases secreted by T. aureoviride mutant 7-121 grown in liquid Mandels medium which contained cell walls of different phytopathogenic fungi: B. cinerea (lane 1); A alternata (lane 2) or F. oxysporum (lane 3). Native PAGE was carried out in 15% polyacrylamide gels at pH 8.8. 100 µL of supernatants of cell wall -grown cultures were loaded into each well.
