Summary
Sulfanilamide induced strong inhibitory effects on the growth, respiration and carbohydrate synthesis by mycelial felts of Rhizoctonia solani. The possible reasons for such inhibitory effects are discussed.
The inhibitory effects of sulfanilamide were almost completely alleviated by the inclusion of p-aminobenzoic (PABA) acid in the culture medium of the fungal mats.
R. solani normally produces certain amounts of PABA and its growth and metabolism is inhibited in presence of excess of it.
