Enhanced formation of 2-phenylethanol in Zygosaccharomyces rouxii due to prephenate dehydrogenase deficiency.

Intravascular Hemolysis Due to Glucose‐6‐Phosphate Dehydrogenase Deficiency in a Patient with Aluminium Phosphide Poisoning

Aluminium Phosphide poisoning and glucose‐6‐phosphate dehydrogenase deficiency are two commonly seen clinical presentations in Iran. However, hemolysis associated with Aluminium Phosphide poisoning is very rare. We report a case of concurrent Aluminium Phosphide poisoning and glucose‐6‐phosphate dehydrogenase deficiency in a 24 year old man presenting with intravascular hemolysis. Key words...

Formation of 4-hydroxy-2,5-dimethyl-3[2H]-furanone by Zygosaccharomyces rouxii: identification of an intermediate.

The formation of the important flavor compound 4-hydroxy-2,5-dimethyl-3[2H]-furanone (HDMF; Furaneol) from D-fructose-1,6-bisphosphate by the yeast Zygosaccharomyces rouxii was studied with regard to the identification of intermediates present in the culture medium. Addition of o-phenylenediamine, a trapping reagent for alpha-dicarbonyls, to the culture medium and subsequent analysis by high-pr...

Recent allopolyploid origin of Zygosaccharomyces rouxii strain ATCC 42981.

Zygosaccharomyces rouxii strain ATCC 42981 has been reported to have two copies of several genes including HOG1 and SOD2, whereas the type strain of Z. rouxii (CBS 732) has only one. To investigate the structure of the ATCC 42981 genome we sequenced random fragments from this genome and compared the data to the type strain. We found that ATCC 42981 contains two versions of the ribosomal RNA arr...

Evaluation of different chemical preservatives to control Zygosaccharomyces rouxii growth in high sugar culture media

Head bobbing due to succinic semialdehyde dehydrogenase deficiency.

A 9-month-old boy had a short history of “yes-yes” head bobbing (video on the Neurology Web site at www. neurology.org). Mild global delay prompted investigation. Imaging (figure, A–C), biochemical, and molecular findings (table e-1) were consistent with succinic semialdehyde dehydrogenase (SSADH) deficiency. SSADH deficiency, a -aminobutyric acid degradation disorder, may be associated with mo...
