Kinetics of Thermoascus aurantiacus solid-state fermentation on sugar-beet pulp – polysaccharide alteration and production of related enzymatic activities
Applied Microbiology and Biotechnology, 1996Co-Authors: N. Roche, A DurandAbstract:The Fungal solubilization of cell wall components of sugar-beet pulp, during solid-state fermentation of Thermoascus aurantiacus, is reported here. The extracellular Fungal Enzyme activities related to the substrate degradation were also studied. In 120 h, more than 60% of the main sugar-beet pulp polysaccharides, i.e. pectins, arabinose- and glucose-containing polysaccharides, were rapidly brought into solution by the fungus. The slow accumulation of monosaccharides compared to the fast degradation of the polysaccharides suggested that most of the released sugars were consumed by the fungus. The analysis of the Enzymes present in the water extracts of the solid-state cultures proved that the fungus was able to synthesize a complete enzymatic system required for the hydrolysis of the main sugar-beet pulp polysaccharides. The highest Enzyme activities measured were β-glucosidase and α-L-arabinofuranosidase.

Production of rice straw hydrolysis Enzymes by the fungi Trichoderma reesei and Humicola insolens using rice straw as a carbon source.
Bioresource technology, 2017Co-Authors: Takashi Kogo, Yuki Yoshida, Keisuke Koganei, Hitoshi Matsumoto, Taisuke Watanabe, Jun Ogihara, Takafumi KasumiAbstract:Rice straw was evaluated as a carbon source for the fungi, Trichoderma reesei and Humicola insolens, to produce Enzymes for rice straw hydrolysis. The Enzyme activity of T. reesei and H. insolens cultivated in medium containing non-treated rice straw were almost equivalent to the Enzyme of T. reesei cultivated in Avicel medium, a form of refined cellulose. The Enzyme activity of T. reesei cultivated in medium containing NH4OH-treated rice straw was 4-fold higher than Enzyme from cultures grown in Avicel medium. In contrast, H. insolens Enzyme from cultures grown in NH4OH-treated rice straw had significantly lower activity compared with non-treated rice straw or Avicel. The combined use of T. reesei and H. insolens Enzymes resulted in a significant synergistic enhancement in enzymatic activity. Our data suggest that rice straw is a promising low-cost carbon source for Fungal Enzyme production for rice straw hydrolysis.
