An O-acetylated homopolysaccharide of 6-deoxy-D-talose (6-deoxy-alpha-D-talan polymer) was isolated from Burkholderia (Pseudomonas) plantarii strain DSM 6535 by extraction with 2-propanol. The structure (1) of the trisaccharide repeating unit of the polysaccharide was established by studies of the intact and O-deacetylated polysaccharides using(More)
From humus obtained from Stuttgart, a bacterium was isolated with lawsone (2-hydroxy-1,4-naphthoquinone) as selective source of carbon. This bacterium is capable of utilizing lawsone as sole source of carbon and energy. Morphological and physiological characteristics of the bacterium were examined and it was identified as a strain of Pseudomonas putida. The(More)
Juglone-induced cells of Pseudomonas putida J 1 were shown to contain two isofunctional juglone hydroxylases. Both enzymes were purified about 125-fold to homogeneity in polyacrylamide gel electrophoresis. The molecular masses of the native enzymes, as determined by Sephacryl S-200 gel filtration were 59 000 Da for enzyme 1 and 56 000 Da for enzyme 2. The(More)
