  • Patent number: 7553657
    Abstract: The strain of Trichoderma asperellum T34(2) CECT No. 20417 is useful for preparing substrates for biological control of vascular fusariose and death of plants caused by Rhizoctonia solani. The substrates can be peats, composts (hardwood compost, pine bark compost, cork compost, sludge compost from sewage treatment plants, garden residues, etc.) or formulations based on CPV-type compost (compost+peat+vermiculite). The fact that the substrates suppress both Fusarium oxysporum f. sp. lycopersici and Rhizoctonia solani provides an advantage in comparison with other substrates known in prior art. Another advantage is that the use of methyl bromide, a highly harmful product for the environment, in the control of vascular fusariose is avoided.

  • Patent number: 7534610
    Abstract: A cell growth matrix for optimizing 3D organization nutrient delivery, controlling release of differentiation factors and facilitating attachment of cells to a scaffold Colloidal crystals and inverted colloidal crystals are used to form an ordered structure for use as a scaffold for tissue engineering. The porosity of the cell growth matrix may be modified by the selection of particles of appropriate diameter. Further, the surface of colloidal crystals can be easily modified to accommodate many organic species including biomolecules. Layer-by-layer materials are used for tissue engineering to control cell development by using sequential layering of bioactive species wherein the number and order of LBL layers deposited between layers containing a particular protein are controlled. LBL may also be used for timed release of bioactive species. Increased control differentiation factors release and control of cell attachments to the scaffold are achieved to better mimic natural tissue development.
