    J L Kock
    Department of Microbiology and Biochemistry, University of the Orange Free State, South Africa
    Antonie Van Leeuwenhoek 75:261-6. 1999
    ..We suggest that novel ASA-sensitive oxidised fatty acids (3R-hydroxy-oxylipins) and small hooks located on the surface of these ascospores, are involved...

    J L Kock
    Department of Microbiology and Biochemistry, University of the Orange Free State, Bloemfontein, South Africa
    Antonie Van Leeuwenhoek 77:401-6. 2000
    ..This migration resulted in the binding of these layers to cell walls of adjacent cells. Consequently, 'ghosting' seems a prerequisite for flocculation to occur. However, 'ghosting' alone may not be sufficient to ensure flocculation...

    UNESCO MIRCEN Industrial Biotechnology, Department of Microbiology and Biochemistry, University of the Orange Free State, Bloemfontein, South Africa
    Antonie Van Leeuwenhoek 80:93-9. 2001
    ..On the basis of the available data, we hypothesize that 3-hydroxy oxylipins probably function as adhesives, attaching fungal cells to each other or to other surfaces through entropic based hydrophobic forces and/or hydrogen bonds...

    UNESCO MIRCEN, Department of Microbiology and Biochemistry, University of the Orange Free State, Bloemfontein, South Africa
    Antonie Van Leeuwenhoek 80:311-5. 2001

    A Botha
    Department of Microbiology and Biochemistry, University of the Orange Free State, South Africa
    Antonie Van Leeuwenhoek 75:253-6. 1999
    ..Circa 94% of the total fungal isolates represented Mortierella subgenus Mortierella. The rest of the colony-forming units consisted of Mucor isolates (6.0%) and higher fungi (1.5%). All the Mortierella isolates produced arachidonic acid...
