A 17 kb region from near the right end of chromosome I of Saccharomyces cerevisiae was isolated on recombinant λ bacteriophages. This region contained the PH011 gene which was located only 3.4 kb from the right end of the chromosome. We found that this region also was repeated approximately 13 kb from the end of the chromosome VIII DNA molecule. The(More)
Of 125 microorganisms that were able to use α-hydroxy acid amides as sole nitrogen source, Ochrobactrum anthropi NCIMB 40321 was selected for its ability to hydrolyse racemic amides l-selectively. The substrate specificity of whole O. anthropi cells is remarkably wide and ranges from α-H-α-amino-, α-alkyl-α-amino, N-hydroxy-α-amino acid amides to(More)
Two groups of facultatively fermentative yeasts may be distinguished with respect to anaerobic xylose fermentation, namely yeasts showing no or only very slow ethanol production such as Candida utilis and Pachysolen tannophilus (group 1) and yeasts with a relatively rapid xylose fermentation, for example Pichia stipitis (group 2) (Toivola et al., 1984). In(More)
Computational capacity and memory are limiting factors when simulating large numbers of robots with complex bodies: available physics engines struggle to handle more than a couple of dozens of complex robot bodies. This limits the possibilities of investigating the evolution of robot morphology to small populations with few generations. We present a method(More)
Recent publications dealing with equipment for filling test tubes, flasks, and Petri dishes evidence that the trend towards automation is gaining a firm footing in the microbiological laboratory. Inoculation is another though more complex operation that can be carried out mechanically, Removal and replacement of cotton-wool plugs, and flame-heating of tube(More)
