Project description:The goal of this work was to elucidate the mechanism by which pyruvate is utilized as a substrate in a mutant strain of Methanosarcina barkeri Fusaro. In this study, using RNAseq we gained insight into how the mutant strain modulate its transcriptional profile in order to use pyruvate as a substrate. In addition, we obtained information on how methanogens respond to pyruvate at the transcriptional level. The mRNA from of Methanosarcina barkeri Fusaro DSMZ804 and Pyr+ strains grown on a variety of substrates (methanol, acetate, methanol-acetate, methanol-pyruvate, methanol-pyruvate-acetate) were harvested sequenced and mapped to M. barkeri genome. Pairwise comparisons between two cell lines of the Pyr+ strain and the DSMZ 804 strain were performed in all substrates tested.
Project description:Genomic response of C. elegans after infection with Microbacterium nematophilum.<br><br>The interaction between the nematode Caenorhabditis elegans and a Gram-positive bacterial pathogen, Microbacterium nematophilum, provides a model for an innate immune response in nematodes. This pathogen adheres to the rectal and post-anal cuticle of the worm, causing slowed growth, constipation, and a defensive swelling response of rectal hypodermal cells. To explore the genomic responses that the worm activates after pathogenic attack we used microarray analysis of transcriptional changes induced after 6 hr infection, comparing virulent with avirulent infection.
Project description:Plant growth promoting test in A. thaliana by using biostimulant strain P. megaterium YC4-R4 in liquid inoculant A. thaliana mRNA profiles of 13-day old wild type (WT) mock and WT treated (inoculated with P. megaterium YC4-R4)
Project description:This project is a proteomic comparison of Microbacterium sp. Viu2A exposed to 10 µM nitrate uranyl versus control condition without uranyl. Three sampling time points (30 min, 4h and 24h) were analyzed. The proteomics datasets were obtained using a protein database derived from the Microbacterium sp. Viu2A complete genome.
