Whole-genome metabolic model of built by comparative reconstruction.

Background: is one of the main sources of biomass-hydrolyzing enzymes for the biotechnology industry. There is a need for improving its enzyme production efficiency. The use of metabolic modeling for the simulation and prediction of this organism's metabolism is potentially a valuable tool for improving its capabilities.

Enabling low cost biopharmaceuticals: high level interferon alpha-2b production in Trichoderma reesei.

Background: The filamentous fungus Trichoderma reesei has tremendous capability to secrete over 100 g/L of proteins and therefore it would make an excellent host system for production of high levels of therapeutic proteins at low cost. We have developed T. reesei strains suitable for production of therapeutic proteins by reducing the secreted protease activity.

The effects of extracellular pH and of the transcriptional regulator PACI on the transcriptome of Trichoderma reesei.

Background: Extracellular pH is one of the several environmental factors affecting protein production by filamentous fungi. Regulatory mechanisms ensure that extracellular enzymes are produced under pH-conditions in which the enzymes are active. In filamentous fungi, the transcriptional regulation in different ambient pH has been studied especially in Aspergilli, whereas the effects of pH in the industrial producer of hydrolytic enzymes, Trichoderma reesei, have mainly been studied at the protein level.
