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.

Transcriptomic analyses of Lysinibacillus varians GY32 respiring with electrode or oxygen [RNA-seq K]

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 acetate 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.

Haemophilus influenzae 86-028NP

Project description:Transcriptome analysis of NTHi 86-028NPrpsL, NTHi 86-028NPrpsL∆fur, and NTHi 86-028NPrpsL∆fur(pT-fur) strains Nontypeable Haemophilus influenzae (NTHi) is a commensal microorganism of the normal human nasopharyngeal flora, yet also an opportunistic pathogen of the upper and lower respiratory tracts. Changes in gene expression patterns in response to host microenvironments are likely critical for survival. One such system of gene regulation is the ability to carefully regulate iron uptake. A central regulatory system that controls iron uptake, mediated by the ferric uptake regulator Fur, is present in multiple bacteria, including NTHi. To understand the regulation of iron homeostasis in NTHi, fur was deleted in the NTHi strain 86-028NPrpsL. Using RNA-Seq, we identified both protein-encoding and small RNA genes whose expression was repressed or activated by Fur. Overall design: These data comprise transcriptional anaylses of an rpsL mutant of 86-028NP, an isogenic fur mutant of 86-028NPrpsL and a complemented fur mutant strain. All strains were grown in defined medium containing 10 µg/ml human hemoglobin to mid-log phase. Cells were then harvested and RNA extracted. A total of three biological replicates were generated for these analyses.
