25. Evolutionary relationships among pathogenic Candida species and relatives.
Small subunit rRNA sequences have been determined for 10 of the most clinically important pathogenic species of the yeast genus Candida (including Torulopsis [Candida] glabrata and Yarrowia [Candida] lipolytica) and for Hansenula polymorpha. Phylogenetic analyses of these sequences and those of Saccharomyces cerevisiae, Kluyveromyces marxianus var. lactis, a

27. Degradation of Hydrocarbons by Members of the Genus Candida III. Oxidative Intermediates from 1-Hexadecene and 1-Heptadecene by Candida lipolytica
Candida lipolytica (Phaff) was grown in a mineral-salts medium amended with either 1-hexadecene or 1-heptadecene as substrate. Intermediates of the same chain length as the substrate were isolated and identified by various analytical procedures. The following intermediates of 16 and 17 carbon atoms were identified: ω-unsaturated acids, ω-unsaturated primar

29. Molecular Characterization of Yarrowia lipolytica and Candida zeylanoides Isolated from Poultry
Yeast isolates from raw and processed poultry products were characterized using PCR amplification of the internally transcribed spacer (ITS) 5.8S ribosomal DNA region (ITS-PCR), restriction analysis of amplified products, randomly amplified polymorphic DNA (RAPD) analysis, and pulsed-field gel electrophoresis (PFGE). ITS-PCR resulted in single fragments of 3

30. Isolation of a bioemulsifier from Candida lipolytica.
The yeast Candida lipolytica produced an inducible extracellular emulsification activity when it was grown with a number of water-immiscible carbon substrates. Negligible emulsification activity was produced by this yeast when it was grown with glucose as the carbon substrate. In hexadecane-supplemented cultures, emulsification activity was first detected af

31. Purification and Characterization of Liposan, a Bioemulsifier from Candida lipolytica†
The inducible water-soluble bioemulsifier liposan (M. C. Cirigliano and G. M. Carman, Appl. Environ. Microbiol. 48:747-750, 1984) was purified from the yeast Candida lipolytica. The purification procedure included repeated solvent extractions of a concentrated culture filtrate and Affi-Gel concanavalin A affinity chromatography. The procedure yielded a prepa

32. Role and control of isocitrate lyase in Candida lipolytica.
Mutants of Candida lipolytica that were unable to grow on acetate but able to utilize succinate or glycerol as a sole carbon source were isolated. Amongst the mutants isolated, one strain (Icl-) was specifically deficient in isocitrate lyase activity, whereas another strain (Acos-) was deficient in acetyl coenzyme A synthetase activity. Since the Icl- mutant

33. Assimilation of chlorinated alkanes by hydrocarbon-utilizing fungi.
The fatty acid compositions of two filamentous fungi (Cunninghamella elegans and Penicillium zonatum) and a yeast (Candida lipolytica) were determined after the organisms were grown on 1-chlorohexadecane or 1-chlorooctadecane. These organisms utilized the chlorinated alkanes as sole sources of carbon and energy. Analyses of the fatty acids present after grow

34. Cell surface topography of Candida and Leucosporidium yeasts as revealed by scanning electron microscopy.
The cell surface topography of the following yeast strains was examined by scanning electron microscopy: Candida slooffii, C. lipolytica, Leucosporidium frigidum, and L. nivalis. Multipolar and lateral budding were observed in the Candida yeasts in contrast to bipolar budding in the Leucosporidium species. The cell surface topography and the morphology of th

35. Molecular and functional analysis of the LYS1 gene of Candida albicans.
The LYS1 gene of Candida albicans has been localized to a 1.8-kb DNA fragment present on the plasmid YpBRG2. YpBRG2 has been shown to complement the saccharopine dehydrogenase mutant Stx4-4A of Saccharomyces cerevisiae. Transformants of S. cerevisiae Stx4-4A exhibited significant saccharopine dehydrogenase activity, and cells that had lost YpBRG2 after nonse

36. Extracellular Proteinases of Yeasts and Yeastlike Fungi1
Approximately 800 yeasts and other fungi, representing over 70 species, were tested for extracellular caseinolysis. Isolates of a variety of genera, including Aureobasidium, Cephalosporium, Endomycopsis, Kluyveromyces, and numerous sporobolomycetes, demonstrated significant proteolytic activity. Caseinolysis was not necessarily correlated with gelatin liquef
