    Karyology and hyphal characters as taxonomic criteria in Ascomycetous black yeasts and related fungi (1991)
    Springer

    ISSN: 1572-9699

    Notes: Abstract Mycelial development of seventy-three strains of black yeasts and related fungi were studied, and numbers of nuclei per hyphal cell were counted. Two main patterns were apparent in expanding hyphae, viz. (1) uninucleate expanding hyphal cells, septum formation strictly following mitosis, and (2) multinucleate, branched, aseptate hyphal tips, septa being formed in a later stage, leading to oligo- or uninucleate mature cells. Characteristic genera in the two groups areExophiala andAureobasidium, respectively. InZasmidium and in someRamichloridium species all mycelial cells are oligonucleate. The character is indicative for relationships at the family level in black yeasts.

    Distinction of species in Aureobasidium and related genera by PCR-ribotyping (1996)
    Springer
    Antonie van Leeuwenhoek 69 (1996), S. 323-329 
    Details
    ISSN: 1572-9699
    Keywords: black yeasts ; Dothideaceae ; Aureobasidium ; Kabatiella ; Hormonema ; Selenophoma ; dothiora ; Pringsheimia ; taxonomy ; PCR-ribotyping

    Topics: Biology
    Notes: Abstract Taxonomic markers for differentiation of the anamorph genera Aureobasidium, Hormonema and Kabatiella were developed using PCR-ribotyping with the primers 5.8S-R and LR7 for amplification and the restriction enzymes Alul, DdeI, Hhal, MspI and RsaI for digestion. Aureobasidium and Hormonema are optimally differentiated with MspI; DdeI is particularly useful to distinguish aureobasidium, Kabatiella and Selenophoma. Relationships of the anamorph genera Aureobasidium, Hormoneng and Kabatiella with the teleomorph genera Pringsheimia and Dothiora are discussed.

    Coenzyme Q systems in ascomycetous black yeasts (1989)
    Springer
    Antonie van Leeuwenhoek 56 (1989), S. 349-356 
    Details
    ISSN: 1572-9699
    Keywords: coenzyme Q ; ubiquinones ; black yeasts ; Exophiala ; Aureobasidium ; Hormonema ; yeast-like fungi ; ascomycetes ; taxonomy ; chemotaxonomy

    Topics: Biology
    Notes: Abstract 72 Strains belonging to 44 species of ascomycetous black yeasts were analyzed for their coenzyme Q systems. Prevalent were Q-10 and dihydrogenated Q-10 systems. Members of the Dothidealean suborder Dothideineae have Q-10 (H2), while those belonging to the suborder Pseudosphaeriineae mostly have Q-10. The anamorph genus Exophiala Carmichael and the teleomorph genus Capronia Sacc. seem to be heterogenous.

    Conidiogenesis, nutritional physiology and taxonomy ofAureobasidium andHormonema (1994)
    Springer

    ISSN: 1572-9699
    Keywords: black yeasts ; Aureobasidium ; Hormonema ; Kabatiella ; Pringsheimia ; Dothiora ; Dothidae ; Dothideaceae ; conidiogenesis ; physiology ; taxonomy

    Topics: Biology
    Notes: Abstract Diagnostic criteria for the distinction of the slightly osmophilic species,Aureobasidium pullulans, and the opportunistic pathogen on conifers,Hormonema dematioides, are provided. Reliable identification requires a combination of characters of conidiogenesis, expansion growth and assimilative abilities. Relationships with species ofKabatiella, and with the teleomorph generaPringsheimia, Dothidea andDothiora, all havingHormonema-like cultural states, are discussed. An identification key is provided.

    Intraspecific variability and exopolysaccharide production inAureobasidium pullulans (1995)
    Springer
    Antonie van Leeuwenhoek 68 (1995), S. 57-63 
    Details
    ISSN: 1572-9699
    Keywords: Aureobasidium ; Hormonema ; black yeasts ; PCR-ribotyping ; UP-PCR ; exopolysaccharides

    Notes: Abstract Forty seven strains of the black yeasts,Aureobasidium pullulans andHormonema dematioides, and the type strain ofHormonema macrosporum were examined using PCR-ribotyping and universally primed PCR with subsequent hybridization. Four groups (populations) were distinguished withinA. pullulans with PCR-ribotyping, which largely coincided with UP-PCR/hybridization groups. The UP-PCR technique revealed a greater degree of heterogeneity between the groups studied. Five strains identified asHormonema dematioides on the basis of physiological and morphological data formed a group recognizable with PCR-ribotyping and UP-PCR/hybridization, which also includedH. macrosporum. Aureobasidium pullulans is characterized by the absence of RsaI restriction sites in rDNA amplified with primers 5.8S-R and LR7, whileHormonema species possessed several bands after RsaI digestion. For analysis of distance between populations, PCR-ribotyping with AluI and MspI is sufficient. Strains ofA. pullulans produce exopolysaccharides in liquid media with different nitrogen sources, while the strains ofHormonema synthesize minor amounts of polysaccharides in media with peptone. Populations ofA. pullulans differ slightly from each other in their optimal, medium-dependent production of polysaccharides.
