Abstract: MLX1034 is from Polaribacter sp. Q13, and has the amino acid sequence of the 1,3/1,4-xylanase MLX1034 is listed in SEQ ID NO.1; a nucleotide sequence of the gene is listed in SEQ ID NO.2; the 1,3/1,4-xylanase MLX1034 in the invention is capable of efficiently and specifically degrading 1,3/1,4-xylan and producing xylooligosaccharides with DP values above one; in addition, the physical and chemical properties of the 1,3/1,4-xylanase MLX1034 are stable enough to hydrolyze 1,3/1,4-xylan at room temperature; the 1,3/1,4-xylanase MLX1034 is suitable for the industrial production of red algal xylooligosaccharides at low energy costs.

Abstract: A method, an apparatus, and a system for migrating a virtual machine. In this solution, a to-be-migrated virtual machine is determined from a server with a largest temperature value at a current time, and the to-be-migrated virtual machine is migrated to a destination server. Because a temperature value of the destination server available after the to-be-migrated virtual machine is migrated to the destination server is less than the largest temperature value of the server with the largest temperature value at the current time available before the virtual machine is migrated out from the server with the largest temperature value at the current time, a largest temperature value of a server in a data center is reduced; in addition, during refrigeration, less energy is consumed if the largest temperature value is smaller. Therefore, this solution reduces energy consumed in a refrigeration process.
