Project description:Indole-3-acetic acid (IAA), knows as common plant hormone, is one of the most distributed indole derivatives in the environment. A novel strain, which was able to use IAA as sole source of carbon and nitrogen, was isolated from farm soil, identified and classified as Pseudomonas composti LY1 based on 16S rRNA sequence and genome analysis. The optimal growth conditions for LY1 with IAA are characterized. Proteome profile of strain LY1 to IAA and citrate were analyzed and compared using label free strategy with LC-MS/MS.
Project description:Lysinibacillus varians GY32 is a filamentous bacteria that can generate electricity in microbial fuel cells. To find potential genes participating in the electron transfer to electrode of Lysinibacillus varians GY32, we compared the gene expression profiles of this bacteria with yeast extract as electron donor and two electron acceptors, i.e. oxygen and electrode in microbial fuel cells. The results showed that several cytochrome c genes might play specific roles in the extracellular electron transfer to electrode in this strain.
