“…The basis of the method is that pectin lyase activity is higher at high pH and is stimulated in the presence of calcium ions. These factors lower the activity of polygalacturonase, which is inhibited at higher calcium concentrations (Blais et al, 1992). Hence, the use of these parameters allows the suppression of PG activity and an increase in PL activity.…”

“…Many fungi are known to secrete multiple forms of pectinases, the advantages of which being the ability to confer flexibility and a greater adaptive capacity [6,39, 401. Pectin lyase is usually induced at pH 6.5 to 8 in other fungi [22,24,[41][42][43], but production of pectin lyase by T. trogii was obtained when the initial pH of the medium was 3.3. Decomposition of plant cell walls during tissue invasion and pathogenesis is a characteristic feature of numerous plant diseases caused by phytopathogenic fungi.…”
