Effect of Different Media on Growth Kinetics Parameters of Aspergillus ochraceus: an Approach Towards Production of Fungal Biomass

Abstract

The importance of fungi derived polymers and their characterization have provided an impetus polymer industry. The role of culture conditions in biomass production, cannot be ruled out. Media is one such abiotic parameter that play a significant role in growth of fungal biomass. In current study, Aspergillus ochraceus was maintained in three different culture media viz., Potato Dextrose Broth medium (PDB), Yeast Potato Dextrose Broth medium (YPD),and Sabourd’s Dextrose Broth (SDB) for 8 days. The results showed around two fold higher biomass production in Sabourd’s Dextrose Broth. The specific growth rate was higher and doubling time was relatively lower in Potato Dextrose Broth medium (PDB). The results suggest that the biomass may be relatively higher in Sabourd’s Dextrose Broth. The study may be extended to compare the yield of chitosan and their physico-chemical properties.
