Potato Dextrose Agar Powder

Potato Dextrose Agar (PDA) Powder — Microbiological Grade

Catalog Number: AS-1330

Overview

Potato Dextrose Agar (PDA) Powder is a ready-to-reconstitute dehydrated culture medium formulated for the cultivation, enumeration, and maintenance of fungi and yeasts. Prepared from potato infusion and dextrose, PDA provides a nutrient-rich environment that supports vigorous mycelial growth and sporulation across a wide range of fungal species.

As one of the most widely used fungal media worldwide, PDA is a cornerstone medium in microbiology, food safety testing, environmental monitoring, and plant pathology. Its simplicity, reproducibility, and versatility make it indispensable in routine and research laboratories.
