摘要:
The present invention provides a process for degradation of lignocellulosic biomass, which has optionally been pre-treated. It is based on the finding that hydrolysis efficiency of the biomass is enhanced in the presence of a mechanically or chemically treated microorganism capable of producing the respective hydrolytic enzymes. The invention therefore provides a process for degradation of lignocellulosic biomass with integrated produced enzyme cocktails. The invention also provides a process wherein the part of the optionally pre-treated lignocellulosic biomass is incorporated into the final growth medium of the fungus.

The present invention relates to polypeptides having xylanase activity and nucleic acid sequences encoding such polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid constructs as well as methods for producing and using the polypeptides. One specific application of the xylanase is the selective hydrolysis of pentose sugar components of hemicellulose-containing plant biomass. The nucleotide sequence may be used for the production of the xylanase or optimized mutants thereof.

摘要:
A method for selecting or designing a compound expected to modulate the activity of Leukotriene C4 synthase (LTC4S), the method comprising the step of using molecular modelling means to select or design a compound that is predicted to interact with the catalytic site or a substrate binding region of LTC4S, wherein a three-dimensional structure of at least a part of the catalytic site or a substrate binding region of LTC4S is compared with a three-dimensional structure of a compound, and a compound that is predicted to interact with the said catalytic site or substrate binding region is selected. The selected compound may be predicted to bind to at least a part of a region of the structure termed the “GSH substrate binding cavity” (formed by residues including residues Arg51, Arg30, Arg104, Gln53, Asn55, Glu58, Tyr59, Tyr93, Tyr97, Ile27, Pro37, Leu108 of full length human LTC4S, or equivalent residues); the “lipophilic substrate binding crevice” (formed by residues including Ala20, Leu24, Ile27, Tyr59, Trp116, Ala112, Leu115, Leu108, Tyr109, Leu62, Val119, Thr66, Vall6 and Leu17, or equivalent residues); or the “catalytic site” (formed by residues including Arg104 or Arg31, or equivalent residues).
摘要:
A motor vehicle brake system having a hydraulic cable, via which a wheel brake module can be pressurized by a brake medium using brake pressure from a brake cylinder and to which a low pressure accumulator is connected for temporarily receiving excess brake medium, wherein the low pressure accumulator is connected to the hydraulic cable via a backflow line and a return pump interposed in the return line in order to return temporarily stored brake medium, the return pump being cyclically actuated for adjusting the pump capacity such that an activation occurs within each braking cycle during a portion of pump cycles that corresponds to the pump capacity, is intended to provide particularly high operational safety while also providing a comfortable pedal sensation.
摘要:
A brake pressure control system is proposed which operates on the fluid-return principle. This system includes a low pressure accumulator which must be emptied upon termination of a braking operation with brake pressure control. In this way, the emptying period is kept as short as possible. To this end, the pump is driven for a defined period. In this emptying period, the motor is controlled by pulse-width modulation, and the electromotive counterforce is measured in the phases of the control signal in which no voltage is applied to the motor. This counterforce is a standard of the rotational speed of the motor or the rotational speed of the connected pump. When the rotational speed or the rotational speed variation exceeds a given value, this can be considered as an indication that the low pressure accumulator is empty. As soon as such a signal appears, the emptying period is terminated by deactivation of the motor.
