Screening of a Marine Algal Extract for Antifungal Activities

Over the past few years algal extracts have become increasingly interesting to the scientific community due to their promising biological properties. Phlorotannin extracts are particularly attractive partly due to their reported antifungal activity against several yeast and dermatophyte strains. The micromethod used for the evaluation of the minimum inhibitory concentration (MIC) and the minimum lethal concentration (MLC) represents an effective and solvent-saving procedure to evaluate the antifungal activity of algae extracts. Here we describe the micromethod for determining the MIC and the MLC of algal extracts by using the example of a purified phlorotannin extract of brown algae.
