Project description:Our research describe the influence of aeration conditions in petri dishes for A. thaliana growth. We analyze the difference between plants grown in standard Petri dish (Non-aerated) and modified Petri dish that include aeration (Aerated). To characterize the differences between those conditions the gene expression analysis was performed. We also wanted to analyze the effect of using a micropore filter, so we designed another experiment with Aerated, Non-aerated and Micropore filter conditions.

Project description:Effects of scouring on Membrane Aerated Biofilm Reactor performance and microbial community composition
Project description:The regulatory role of the Fis protein in fis and in the transcription of several gene regions during mid-exponential and late-stationary phase, and during different growth aeration regimes, has been investigated. Studies were done during those two growth phases and in aerated and non-aerated (microaerobic) conditions, to measure Fis enrichment and binding peaks in strategic gene regions by genome-wide microarray analysis ChIP-chip. This research investigation points to central roles for SPI-1, SPI-2, DNA gyrase and topoisomerase I, the elements of the stringent response, and the regulatory function of Fis-binding patterns, in setting and re-setting the activity of the fis gene and other involved promoters as a function of the growth conditions and aeration regimes experienced by Salmonella.

One sample with four different treatments. Three biological replicates per sample. The Aerated 2 hour sample was set as the control condition for all samples.
Project description:Gene expression profiles of Bacillus subtilis strain AG174 were compared as a function of steady-state external pH during growth with aeration. Aerated overnight cultures were diluted 1:500 and incubated in 250 mL baffled flasks containing potassium-modified Luria-Bertani medium (LBK) buffered with 50 mM HOMOPIPES at pH 6.0, pH 7.0, and pH 9.0. Tubes were incubated at 37°C with aeration (260 rpm) to an optical density at 600 nm of 0.2. For each of the three pH conditions, RNA was isolated from five independent cultures.
