  • Patent number: 7448465
    Abstract: An industrial truck has a steering axle with two axle tree bolster systems located at a lateral distance from each other. Each system has an axle body with an axle shaft (1) and an axle tree bolster (2) located on the lower end of the axle shaft (1). The axle tree bolster (2) and the axle shaft (1) are individual components that are connected with each other. The axle tree bolster (2) is preferably detachably fastened to the axle shaft (1). The rotational position of the axle tree bolster (2) relative to the axle shaft (1) can be adjustable. Means can also be provided for the positive and/or non-positive transmission of a torque from the axle shaft (1) to the axle tree bolsters (2).

  • Publication number: 20080166774
    Abstract: The invention relates to a method for producing an amino acid comprising culturing a microorganism of the genus Corynebacterium or Brevibacterium wherein said microorganism is partially or completely deficient in at least one of the gene loci of the group which is formed by otsAB, treZ and treS, and subsequent isolation of the amino acid from the culture medium.

  • Publication number: 20080160585
    Abstract: The present invention features methods of increasing the production of a fine chemical, e.g., lysine from a microorganism, e.g., Corynebacterium by way of deregulating an enzyme encoding gene, i.e., fructose-1,6-bisphosphatase. In a preferred embodiment, the invention provides methods of increasing the production of lysine in Corynebacterium glutamicum by way of increasing the expression of fructose-1,6-bisphosphatase activity. The invention also provides a novel process for the production of lysine by way of regulating carbon flux towards oxaloacetate (OAA). In a preferred embodiment, the invention provides methods for the production of lysine by way of utilizing fructose or sucrose as a carbon source.
