Effect of carbon source on the mycelial growth and exo-biopolymer production by submerged culture of Paecilomyces japonica

A significant difference was observed in the production pattern of exo-biopolymer and broth rheology during submerged culture of Paecilomyces japonica when two efficient carbon sources (maltose and sucrose) were employed. The maximum concentration of biopolymers in maltose medium (30 g/ l) was highe...

Description
Summary:A significant difference was observed in the production pattern of exo-biopolymer and broth rheology during submerged culture of Paecilomyces japonica when two efficient carbon sources (maltose and sucrose) were employed. The maximum concentration of biopolymers in maltose medium (30 g/ l) was higher than that in sucrose medium (25 g/ l), whereas maximum mycelial concentration displayed an inverse result ( i.e., 25 g/ l in sucrose medium and 20 g/ l in maltose medium). The broth rheology and morphology of P. japonica were also markedly different between the two culture media.
