Surface thermodynamics of pellet formation in Aspergillus niger

Biotechnology Letters Aims and scope Submit manuscript

Abstract

The fungal pellets were formed from the surface thermodynamic balance between fungal cell and liquid media. The Gibbs free energy of pellet formation of the initial culture media (−73 ∼ −81 ergs/cm2) were increased to −13 ∼ −46 ergs/cm2 at 48 h. FTIR analysis showed that factors inducing pellet formation simultaneously increased the cell wall hydrophobicity of Aspergillus niger.
