A SD-1 strain of Klebsiella pneumoniae from mink and its application are disclosed, wherein the collection number of the Klebsiella pneumoniae is CGMCC NO: 17901. The Klebsiella pneumoniae SD-1 strain can be used for preparing a vaccine. The preferred form of the vaccine is an inactivated vaccine. The SD-1 strain of Klebsiella pneumoniae was screened from minks that died after vaccination. Compared with the current Klebsiella pneumoniae, the strain has mutated and is a new type of pathogenic strain. Vaccine prepared from the SD-1 strain provides better immune protection for minks.

The present disclosure provides a novel aldehyde synthase gene having activity of synthesizing a medium-chain aldehyde. Such gene encodes a protein comprising the amino acid sequence as shown in SEQ ID NO: 2.

Methods and systems are provided for generating and utilizing a bacterial composition that comprises at least one genetically engineered bacterial strain that fixes atmospheric nitrogen in an agricultural system that has been fertilized with more than 20 lbs of Nitrogen per acre.

The present invention concerns a new method for the production of 1,3-propanediol comprising culturing a recombinant microorganism converting glycerol into 1,3-propanediol and overexpressing the hcpR and/or frdX gene on a medium comprising glycerine. A recombinant microorganism for the production of 1,3 propanediol from glycerol, wherein said microorganism converts glycerol into 1,3-propanediol and 10 overexpresses the hcpR and/or the frdX gene.

Methods and systems are provided for generating and utilizing a genetically engineered bacterium comprising a modification in glnD, wherein said modification is selected from the group consisting of: deletion of the entire gene, deletion of substantially the entire gene, deletion of an ACT domain, deletion of more than 50% of an ACT domain, deactivation of an ACT domain, and deactivation of an UTase domain.
