Investigation of the factors influencing the molecular weight of porphyran and its associated antifungal activity

- LT and alkali modified sample were found to be lower in molecular weight and contain high sulfur content than HT sample.
- LT sample showed high antifungal activity than HT and CS samples.
- Alkali modified sample also shows antifungal activity when compared against CS and HT sample.
- Porphyran with low molecular weight and high sulfur content having potential antifungal activity.
