Isolation of gliotoxin producing T. virens strains from soil. (A) Gliotoxin producing T. virens strains were isolated and cultured on PDA medium. (B) Analysis of gliotoxin production by T. virens strains using TLC. Four days old culture filtrates were extracted with chloroform. Extracts were spotted on TLC plates and sprayed with silver nitrate. Presence of brown colour band indicates the gliotoxin. GT gliotoxin, Std standard gliotoxin.
