The most commonly used fungal DNA extraction techniques require enzymatic digestion or hazardous chemicals. Here, we describe a quick non-enzymatic salt-out method that we developed for isolating high-quality DNA from various fungal species. DNA was extracted from four species of typical fungi, including Saccharomyces cerevisiae, Hansenula polymorpha, Candida albicans, and Aspergillus flavus. Results that we obtained from agarose gel electrophoresis and spectrophotometry verified the integrity, high quality, and purity of the extracted DNAs. Also, PCR amplification and restriction enzyme digestion confirmed the efficiency of the extracted DNAs in molecular biology applications. © 2023 Wiley Periodicals LLC.
