Project description:The Gram-negative photoheterotrophic bacterium Dinoroseobacter shibae is a member of the high abundant marine Roseobacter group. In the ocean, OMVs have about the same abundance as bacteria, a distinct depth distribution, and contain DNA from a variety of marine bacterial taxa. In the present study, we determined the abundance, size, and ultrastructure of membrane vesicles of D. shibae and analysed the protein inventory of the soluble and membrane fractions of cells and vesicles in order to study the origin of OMV membranes and content. The proteomic analyses were complemented by fatty acid analyses.
Project description:This SuperSeries is composed of the following subset Series: GSE25579: Time series analysis of the transition from dark to light growth of Dinoroseobacter shibae DFL12 GSE25581: Time series analysis of the transition from light to dark growth of Dinoroseobacter shibae DFL12 Refer to individual Series
Project description:Transcriptomes of Dinoroseobacter shibae DSM16493 wild type and clpX knockout mutant were recorded under white and blue light and in dark.
Project description:Light dependent gene expression in D. shibae wildtype compared to the gene expression in the transposonmutants D. shibae Dshi_1135::Tn, D. shibae ppaA::Tn and D. shibae ppsR::Tn. Dinoroseobacter shibae DFL12T (DSM 16493T) and the transposonmutants D. shibae Dshi_1135::Tn, D. shibae ppaA::Tn and D. shibae ppsR::Tn were grown in artificial saltwater minimal medium (SWM) in baffled flasks shaking at 180 rpm and 30 °C and incubation was performed under light, dark and bluelight conditions. D. shibae wild type and mutant strain were grown under aerobic conditions up to the mid exponential growth phase (OD578 nM 0.5).
Project description:Dinoroseobacter shibae DFL12T was cultured with/without phage R2C, and gene expression was analyzed at 60 min and 140 min during the incubation
