Fungi belonging to the genera 'Trichoderma and Gliocladium' are soil- bourne saprophytes which have been used for industrial and agricultural applications for decades. Some strains produce enzymes and antibiotics while others are useful as biological agents for the protection of plants against pathogens. This second volume of two describes the commercial uses of 'Trichoderma and Gliocladium', beginning with an in depth discussion of the degradation of polysaccharides and macromolecules by fungal enzymes. The application of the fungi in biocontrol for agricultural purposes is then examined. The final section of this volume deals with protein production and the utilisation of Trichoderma enzymes by various industries.
