Publisher Summary This chapter studies the genus Aciculoconidium. In asexual reproduction cells divide by multilateral budding, are ovoid or ellipsoidal, and occur singly, in short chains, and in clusters. Branched septate hyphae are present and form blastoconidia. Terminal needle-shaped blastoconidia are also formed and are rounded at the base and pointed at the top. Asexual endospores are not formed. Sexual reproduction is unknown. The chapter also discusses physiology/biochemistry and phylogenetic placement of the genus in which sugars are fermented, nitrate is not assimilated, coenzyme Q-9 is present, and the diazonium blue B reaction is negative. The type species taken is Aciculoconidium aculeatum. The phylogenetic placement of the genus Aciculoconidium among ascomycetous yeasts was determined from analysis of D1/D2 LSU ribosomal RNA gene sequences, which showed Aciculoconidium to be weakly associated with Yarrowia lipolytica, Kodamaea ohmeri, and several species of Candida. |
