Temperature dependence of the proteome profile of the psychrotolerant pathogenic food spoiler Bacillus weihenstephanensis type strain WSBC 10204

ABSTRACT: Bacillus weihenstephanensis is a subspecies of the Bacillus cereus sensu lato group of spore forming bacteria known to cause food spoilage or food poisoning. The key distinguishing phenotype of B. weihenstephanensis is its ability to grow below 7°C or, from a food safety perspective, to grow and potentially produce toxins in a refrigerated environment. In order to gain insight into to the mechanistic basis of its psychrotolerant phenotype, as well as elucidate relevant aspects of its toxigenic profile, the proteome profiles of cells grown at either 6°C or 30°C were compared.

Stoichiometry and absolute abundance of proteins in the Bacillus cereus spore insoluble fraction determined using a QconCAT approach

Project description:Spores of Bacillus cereus pose a threat to food safety due to their high resistance to the heat or acid treatments commonly used to make food microbially safe. As spores survive these treatments and later resume growth either on foodstuffs or, after ingestion, upon entering the gut they are capable of producing toxins which cause either vomiting or diarrhea respectively. The outer layers of the spore consist primarily of proteins which may serve as potential biomarkers for detection. In order to quantify proteins in the insoluble fraction of the spore coat, a proteomics approach using a QconCAT reference standard was employed which is the first time this is used in a heterogeneous system. This allowed us to determine the abundance of 21 proteins which spanned across three orders of magnitude and together covered 5.66% ±0.51 of the total spore weight. Classification by abundance resulted in functional characterisation of the protein BC_0987, renamed SasS. Furthermore, protein stoichiometry and determination of the abundance of, for instance, germination mediating enzymes provides useful information for model development. And finally, the four most abundant proteins, CotB1, CotB2, CotX and InhA, are presented to be biomarker candidates containing immunogenic epitopes as predicted by the SVMTriP algorithm and being conveniently located in the outermost layers of the spore.

The influence of sporulation medium on the spore coat protein composition of Bacillus subtilis spores.

Project description:Spores are of high interest to the food and health sectors because of their extreme resistance to harsh conditions especially against heat. Earlier research has shown that spores prepared on solid agar plates have a higher heat resistance than those prepared in a liquid medium. It has also been shown that the more mature a spore is the higher is its heat resistance contributed most likely by the progressive cross-linking of coat proteins. The current study for the first time enlightens the effect of sporulation medium on spore proteins. The 14N spores prepared on solid agar medium and 15N metabolically labelled spores prepared in liquid medium differ in their coat protein composition as revealed by LC-FT-MS/MS analyses. The 14N:15N isotopic ratio of the 1:1 mixture of liquid and solid medium cultured spores exposes that most of the identified inner coat and crust proteins are significantly upregulated while most of the outer coat proteins are significantly downregulated for the spores prepared on solid medium relative to the spores prepared in the liquid medium. Medium specific differences in isotopic ratios between the tryptic peptides of expected cross-linked proteins suggest that also the coat protein cross-linking may be medium specific. The spores prepared on solid medium show a higher thermal resistance than the spores prepared in liquid medium. Since the core DPA content is found to be similar in both the spore populations, it appears that the difference in wet heat resistance is connected to the differences in the coat protein composition and assembly. Supporting the proteomic analyses, the electron microscopy analyses show a significantly thinner outer coat layer of the spores cultures on the solid medium.

Linking the Vegetative Cell and Spore Proteomes of Peptoclostridium difficile

Project description:Peptoclostridium difficile, an anaerobic pathogen, known as causative agent of pseudomembranous colitis and nosocomial diarrhoea. It can also form highly resistant endospores which lay the basic foundations of infection prior germination in the human guts. P. difficile exploits toxins TcdA and TcdB as well as a plethora of other proteins to infect the host. The present study is exclusively focused on the interconnection between vegetative cell and spore proteomes. A novel method developed for 15N metabolic labelling of P. difficile vegetative cells has enabled mass spectrometric quantification of relative protein levels of this pathogen. A total of 1095 proteins has been identified over the combined spores and vegetative cells. From this 796 proteins have been relatively and reproducibly quantified between spores and vegetative cells. Of the quantified proteins 80% are common to both the vegetative cells and spores, indicating that pathogenic P. difficile employs a relatively modest proteomic changeover for survival. Also of the identified proteins are 20%putative membrane proteins which may provide essential targets to combat P. difficile infections. Detailed data analysis has qualified potential biomarkers for diagnostic purposes.

Study of Bacillus cereus spore germination and outgrowth in a vegetable food model by means of genome-wide transcriptome analysis

Project description:Pathogenic species belonging to Bacillus cereus sensu lato group possess a high evolutionary advantage in the environment and in food matrices thanks to their capacity to survive as silent spores to harsh environmental insults and grow at relatively low temperatures. Ready to re-heat products are at severe risk for contamination by members of Bacillus cereus s.l. group if not stored at proper conditions. In this work, the goal was to assess, by means of a genome-wide transcriptional assay, the isolated strain Bacillus cereus UC10070 gene expression behind the process of spore germination and consequent outgrowth in an artificially contaminated vegetable-based food model. A vegetable food model subjected to a heat treatment was determined to present favourable conditions for spores germination. Microscopic analyses together with OD measurements were applied to select the key steps of B. cereus cell cycle to be used for the microarray analysis. Using this approach we found a total of 1,646 probe sets differentially expressed and modulated during the entire B. cereus life cycle in the vegetable foodstuff. RNA was isolated from the dormant spores (DS), germinating spores at 40 minutes (GSP), early-log phase at 2h (C2h) and late log phase cells at 12 hours (C12h) after thermal treatment of B. cereus UC10070 previously isolated froma biofilm on a spoiled vegetable-based puree. There were 3 biological replicates (independent cultures) for each condition. Complete genome sequence of B. thuringiensis sv konkukian str. 97-27 (NCBI Reference Sequence: NC_005957.1) was chosen for its high homology with B. cereus s.l. UC10070, to design probes corresponding to 5,197 genes spotted in duplicates onto ElectraSenseH 12K microarrays chip.

Dynamics of Germinosome Formation Interactions between GerD and Germinant Receptor Subunits in Bacillus cereus Spores

Project description:Spores of the bacterium Bacillus cereus can cause disease in humans due to contamination of raw materials for food manufacturing. These dormant, resistant spores can survive for years in the environment, but can germinate and grow when their surroundings become suitable, and spore germination proteins play an important role in the decision to germinate. The dataset attached describes the quantification of the fluorophores of the expressed fusion proteins by label free mass spectrometry.

‘One-pot’ sample processing method for proteome-wide analysis of microbial cells and spores

Project description:Bacterial endospores, the transmissible forms of pathogenic bacilli and clostridia, are heterogeneous multilayered structures composed of proteins. These proteins protect the spores against variety of stresses, thus helping spore survival, and assist in germination, by interacting with the environment to form vegetative cells. Owing to the complexity, insolubility, and dynamic nature of spore proteins, it has been difficult to obtain their comprehensive protein profiles. The intact spores of Bacillus subtilis, Bacillus cereus, and Peptoclostridium difficile and their vegetative counterparts were disrupted by bead-beating in 6M urea under reductive conditions. The heterogeneous mixture was then double-digested with LysC and trypsin. Next, the peptide mixture was pre-fractionated with Zwitterionic hydrophilic interaction liquid chromatography (ZIC-HILIC) followed by reverse phase LC-FT-MS analysis of the fractions. ‘One-pot’ method is a simple, robust method that yields identification of >1000 proteins with high confidence, across all spore layers from Bacillus subtilis, Bacillus cereus, and Peptoclostridium difficile. This method can be employed for proteome-wide analysis of non-spore-forming as well as spore-forming pathogens. Analysis of spore protein profile will help to understand the sporulation and germination processes and to distinguish immunogenic protein markers.

Bacteria in biogas digestates for reduced climate forcing

Project description:Mitigation of N2O-emissions from soils is needed to reduce climate forcing by food production. Inoculating soils with N2O-reducing bacteria would be effective, but costly and impractical as a standalone operation. Here we demonstrate that digestates obtained after biogas production may provide a low-cost and widely applicable solution. Firstly, we show that indigenous N2O-reducing bacteria in digestates grow to high levels during anaerobic enrichment under N2O. Gas kinetics and meta-omic analysis show that the N2O respiring organisms, recovered as metagenome-assembled genomes (MAGs) grow by harvesting fermentation intermediates of the methanogenic consortium. Three digestate-derived denitrifying bacteria were obtained through isolation, one of which matched the recovered MAG of a dominant Dechloromonas-affiliated N2O reducer. While the identified N2O-reducers encoded genes required for a full denitrification pathway and could thus both produce and sequester N2O, their regulatory traits predicted that they act as N2O-sinks in the current system. Secondly, moving towards practical application, we show that these isolates grow by aerobic respiration in digestates, and that fertilization with these enriched digestates reduces N2O emissions. This shows that the ongoing implementation of biogas production in agriculture opens a new avenue for cheap and effective reduction of N2O emissions from food production.
