Sulfathiazole sodium salt is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA). It can also be used in biological study of thermotherapy and sulfonamide antibiotics deciphered Cyanobacteria and Proteobacteria microbiome in huanglongbing-affected Citrus paradise and Citrus limon.

Sulfathiazole is a sulfonamide antibiotic that blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. Sulfathiazole is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA), which is required for bacterial synthesis of folic acid. It is active against Gram positive bacteria, Gram negative bacteria and Chlamydia. Mode of resistance is via the alteration of dihydropteroate synthase or alternative pathway for folic acid synthesis.
