  • Preparation of thaumatin sweeteners
    Patent number: 5932438
    Abstract: Thaumatins, protein sweeteners, are obtained through the expression of artificial, synthetic and substantially optimized genes, preferably in filamentous fungi such as Penicillium roquefortii, Aspergillus niger and Aspergillus niger var. awamori. Preparing substantially optimized artificial genes allows for high protein expression, making the process useful for industrial production of this valuable sweetener. Thaumatins may be obtained extracellularly and intracellularly. Intracellular production provides thaumatin-containing fungi that can be used per se in animal feed without prior separation of the fungal mycelium.

  • Cephalosporium acremonium
    Patent number: 4753877
    Abstract: The provision of Cephalosporium acremonium resistant to the aminoglycoside G418 allows the use of this aminoglycoside as a marker to select aminogylcoside-resistant cells of Cephalosporium acremonium from non-resistant cells of Cephalosporium acremonium. Aminoglycoside resistance can be imparted by transformation of Cephalosporium acremonium with a suitable vector.
