TranscriptomicsCharacterization of PlcRa, a new PlcR-like regulator involved in oxidative stress response and cysteine metabolism during early stationary phase in Bacillus cereus
PlcR, the major virulence transcriptional regulator in the Bacillus cereus group belongs to the RNPP quorum sensor family and is activated through interaction with the secreted heptapeptide PapR7 used as a signalling molecule. We identified using modeling analysis a structural homologue of PlcR, Plc...

ProteomicsSigB modulates expression of novel SigB regulon members via Bc1009 in non-stressed and heat-stressed cells revealing its alternative roles in Bacillus cereus
Protein samples were measured using the LC-MS/MS platform containing reversed-phase nano liquid chromatography (nano Acquity M-class UPLC) (Waters Corporation, Massachusetts, USA), which was coupled to nanospray ionization tandem mass spectrometry with traveling wave ion mobility using high-definiti...

TranscriptomicsA novel hybrid kinase is essential for regulating the σB-mediated stress response of Bacillus cereus.
A common bacterial strategy for monitoring environmental challenges is to use two-component systems, which consist of a sensor histidine kinase (HK) and a response regulator (RR). In the food-borne pathogen Bacillus cereus, the alternative sigma factor σB is activated by the RR RsbY. Here we presen...

TranscriptomicsTranscriptomic and physiological responses of Bacillus cereus to organic and inorganic acid down-shocks
Comparative phenotype and transcriptome analyses were performed with Bacillus cereus ATCC 14579 exposed to acid down-shock to pH 5.5 set with different acidulants. When acidified with hydrochloric acid (HCl), growth was diminished, whereas 2 mM undissociated lactic acid (HL) or acetic acid (HAc) sto...

TranscriptomicsTranscriptome comparison between Bacillus cereus ATCC 10987 cells with and without iron starvation
In this study we compared the transcriptomic profiles of cells grown in BHI, BHI supplemented with FeCl3, BHI supplemented with iron scavenger Bipyridine and both iron and the scavenger. Liquid cultures grown in above mentioned four conditions with different iron availability were sampled at 5 h (Ex...

TranscriptomicsTranscriptome comparison between Bacillus cereus ATCC 14579 wildtype (WT), RpoN (Sigma 54) deletion mutant and the complemented strain.
RpoN was shown to have a pleiotropic role in different microorganisms. This study was performed to elucidate role in B. cereus. In this study we compared the transcriptomic profiles of the WT, rpoN mutant and the complemented strain in aerated and static growth conditions. Matrix is compatible with ...

TranscriptomicsEthanol stress response in Lactobacillus plantarum WCFS1
Transcriptome profiles of control Lactobacillus plantarum WCFS1 cells were compared with 8% ethanol adapted cells and with 10 min or 30 min 8% ethanol shocked cells. A continuous culture was performed in duplicate on medium containing ehtanol (tE). A shock experiment was performed in duplicate in wh...
