Project description:Streptomyces jumonjinensis NRRL 5741 cultured on three different media, extracted with two different solvents, detected in both positive and negative ionization mode
Project description:We isolated and sequenced mRNA from Streptomyces venezuelae grown on two different solid media that promote exploratory behaviour in this bacterial species. The data was analyzed using DeSeq2 to identify genes that undergo changes in expression over time as well as differences in gene expression patterns between the two media conditions.

Project description:This project aims to discover novel bioactive compounds from Streptomyces isolated from the rhizosphere from wild medicinal plants from Hamedan province, Iran. Proteomics is used to assist in discovery and characterization of the compounds. Streptomyces isolates are grown on ISP-4 medium for three days, proteins were extracted and analysed by shotgun proteomics.
Project description:In order to define the impact of phosphate (Pi) availability on cellular metabolism the project aimed to perform a comparative analysis of the proteomes of two Streptomyces strains with different abilities to produce antibiotics, S. coelicolor and S. lividans as well as of the pptA mutant of S. lividans, grown low (1mM) and high (5mM) phosphate (Pi) availability conditions. Interestingly, in contrast to most Streptomyces species, S. coelicolor produces more antibiotics in Pi proficiency than in Pi limitation, S. lividans does not produce antibiotics in any Pi conditions and the pptA mutant produces antibiotics only in Pi limitation. This in-depth proteomic comparison of three Streptomyces strains (S. coelicolor, S. lividans wt and pptA mutant), in different growth conditions (time and Pi concentration in the medium) was performed on four biological replicates. Protein abundance changes were determined using two label-free mass spectrometry based-quantification methods: spectral count (SC) and MS1 ion intensities named XIC (for eXtracted Ion Current). Our proteomic data reveal for the first time, the impact of Pi availability on the abundance of approximately 4000 proteins of these Streptomyces strains with different abilities to produce antibiotics. The most striking feature differentiating these strains was the much higher abundance of enzymes of the respiratory chain in both phosphate conditions in S. coelicolor compared to the S. lividans strains.
Project description:We performed ribosome profiling which is the deep-sequencing of mRNA fragments protected by translating ribosome for two Streptomyces species through different growth phases to provide the translatome data
Project description:To investigate the function of organic nitrogen on clavulanic acid biosynthesis in Streptomyces clavuligerus, we established F613-1 strain cells cultured in MH fermentation medium and ML fermentation medium. We then performed gene expression profiling analysis using data obtained from RNA-seq of 2 different medium at three time points.
