The antibiotic “Gliotoxin” is isolated from—

✅Explanation
-Trichoderma viride is a well-known fungus with biocontrol properties. It produces several secondary metabolites, including the antibiotic gliotoxin. Gliotoxin has shown activity against various fungi and bacteria, making Trichoderma viride valuable in agriculture and biocontrol applications.

📌Other Options Explanations:
-Option B: Gliocladium virens: This fungus is known for producing antibiotics, but its primary metabolite is gliovirin, not gliotoxin.
-Option C: Gibberella fujikori: This plant pathogen causes bakanae disease in rice and is known for producing gibberellins (plant growth hormones), not antibiotics.
-Option D: Aspergillus terreus: While this fungus produces several secondary metabolites with pharmaceutical potential, gliotoxin is not one of them. It is known for producing lovastatin, a cholesterol-lowering drug.
