A genetically engineered bacterium includes a genome of theand a mutant encoding gene hisG* of aATP phosphoribosyl transferase HisG on the genome, and the gene hisG* is strongly expressed to enhance activity of a key enzyme HisG for histidine synthesis. The gene hisG* has a nucleotide sequence as shown in SEQ ID NO: 1; a copy number of histidine operon genes hisDBCHAFI of theis further increased on the genome to enhance a terminal synthetic route of histidine; an encoding gene lysE from an arginine/lysine transportprotein of theis further integrated to the genome and strongly expressed to promote the intracellular histidine secrete to the extracellular space; and an encoding gene rocG of glutamate dehydrogenase ofis further integrated to the genome and strongly expressed to promote generation of histidine.

A file data restoring system and method of a computer operating system and software thereof are applied in the installation of an operating system into a client computer. Divide the file data corresponding to the operating system into data blocks according to an appointed data size. Generate a check code for each of the data blocks to form a sequence list of original check codes and a sequence list of target check codes. Compare the sequence list of original check codes with the sequence list of target check codes, after installing the operating system into the computer. If the comparison result is inconsistent, a restoring call information is sent out. The position of the inconsistent check code is acquired through the restoring call information and the comparison result. The original file data corresponding to the position of the check code is read and restored to a corresponding target file.
