Abstract: The present disclosure relates to Lactiplantibacillus plantarum for degrading tannins and saponins, and a use thereof. The present disclosure is intended to solve the problem that the existing silage has a low utilization rate due to anti-nutritional factors such as tannins and saponins. The present disclosure provides Lactiplantibacillus plantarum P91 with an accession number of CGMCC No. 27567, which has acid resistance, a high growth rate, a strong carbon source-utilizing ability, and an excellent comprehensive acid-production ability, and can reduce a pH, well improve the palatability of silage, and reduce anti-nutritional factors in silage. Therefore, the present disclosure can effectively solve the problem that a silage raw material has a high content of anti-nutritional factors such as tannins and saponins, and overcome the adaptability problem of a lactobacillus to a raw material, thereby improving an activity of the lactobacillus and a quality of silage fermentation.

Abstract: A PCIe channel switch includes multiple PCIe channels and a control circuit. The PCIe channels can connect to a host device. Each PCIe channel of the PCIe channels can connect the host device with an electronic device via a respective PCIe device. The control circuit can control the on/off state of each PCIe channel of the PCIe channels. The control circuit can select a PCIe channel of the PCIe channels to be turned on, and turns off the other channels of the PCIe channels when the selected PCIe channel is on, thereby enabling the host device to communicate with a selected electronic device through the selected PCIe channel.

Abstract: A data transmission apparatus includes: a first port and a second port which are selected by a first control signal; a first signal path and a second signal path which are selected by a second control signal. When a memory card satisfies a first condition, the first control signal selects the first port and the second control signal selects the first signal path, the data transmission apparatus connects the host device and the memory card via the first port and the first signal path and works in a first transmission mode. When the memory card satisfies a second condition, the first control signal selects the second port and the second control signal selects the second signal path, the data transmission apparatus connects the host device and the memory card via the second port and the second signal path and works in a second transmission mode.

Abstract: A satellite navigation receiver includes a processing unit, a clock generator, and a power management interface. The processing unit is operable for locating the satellite navigation receiver according to multiple satellite signals. The clock generator coupled to the processing unit is operable for providing a reference clock to the processing unit. The power management interface coupled to the processing unit and the clock generator is operable for switching the satellite navigation receiver in multiple operation states. The operation states include a sleep state in which the processing unit is powered off and the clock generator is powered on.
