  • Reducing branching and enhancing fragmentation in culturing filamentous microorganisms
    Publication number: 20060078981
    Abstract: The invention relates to the field of microorganisms and in particular to the culturing of microorganisms. The invention provides means and methods for enhancing the culturing properties of filamentous microorganisms, in particular filamentous fungi. The means and methods according to the invention comprise reducing branching and/or enhancing the fragmentation of filamentous microorganisms, whereby their liquid culturing properties are improved. In one embodiment, this is achieved by providing the microorganisms with activity capable of enhancing fragmentation and/or reducing branching, such as the activity in which, e.g., Streptomyces griseus is encoded by ssgA.
