- Isolation of Bacillus cytotoxicus from various commercial potato products.

Electronic address: Matthias.Contzen@cvuas.bwl.de.2Chemisches und Veterinäruntersuchungsamt (CVUA) Stuttgart, Schaflandstr. 3/2, D-70736 Fellbach, Germany.AbstractBacillus (B.) cytotoxicus is a newly described thermotolerant member of the Bacillus cereus group. This potential foodborne pathogen had so far only been isolated from vegetable products, including mashed potatoes. Here we report the detection of B. cytotoxicus in a variety of potato products taken on retail level or from catering establishments (n=151). Identification of isolates as B. cytotoxicus was performed after enrichment at 50°C, followed by differentiation using Fourier transform-infrared spectroscopy and detection of the specific cytK-1 gene by PCR. Thirty-five percent of all samples were positive for B. cytotoxicus. Highest prevalence was found in dehydrated potato products (44/62=71%) such as powder for mashed potatoes and products made thereof. B. cytotoxicus was not detected in products that were evidently made directly from potatoes (n=24) but in one sample of raw potatoes (n=10; 10%). The high prevalence of this thermotolerant pathogen in potato products could pose a risk for consumers, especially if prepared foods are held at improper holding temperatures.

- Sodium hydrosulfide induces systemic thermotolerance to strawberry plants through transcriptional regulation of heat shock proteins and aquaporin.
- Christou A, Filippou P, Manganaris GA, Fotopoulos V.AbstractBACKGROUND: Temperature extremes represent an important limiting factor to plant growth and productivity. The present study evaluated the effect of hydroponic pretreatment of strawberry (Fragaria x ananassa cv. 'Camarosa') roots with an H2S donor, sodium hydrosulfide (NaHS; 100 muM for 48 h), on the response of plants to acute heat shock treatment (42[degree sign]C, 8 h).

- Cyanobacterial Heat Shock Response: Role and Regulation of Molecular Chaperones.
- Rajaram H, Chaurasia AK, Apte SK.Author information Molecular Biology Division, Bhabha Atomic Research Centre, India;AbstractCyanobacteria constitute a morphologically diverse group of oxygenic photoautotrophic microbes which range from unicellular to multicellular, and non-nitrogen-fixing to nitrogen-fixing types. Sustained long term exposure to changing environmental conditions, during their three billion years of evolution, has presumably led to their adaptation to diverse ecological niches. The ability to maintain protein conformational homeostasis (folding-misfolding-refolding or aggregation-degradation) by molecular chaperones holds the key to the stress adaptability of cyanobacteria. Though cyanobacteria possess several genes encoding DnaK and DnaJ family proteins, these are not the most abundant Hsps, as is the case in other bacteria. Instead, the Hsp60 family of proteins, comprising two phylogenetically conserved proteins, and small Hsps are more abundant during heat stress. The contribution of the Hsp100 (ClpB) family of proteins and of small Hsps in the unicellular cyanobacteria (Synechocystis and Synechococcus) as well as that of Hsp60 proteins in the filamentous cyanobacteria (Anabaena) to thermotolerance has been elucidated. The regulation of chaperone genes by several cis elements and trans-acting factors has also been well documented. Recent studies have demonstrated novel transcriptional and translational (mRNA secondary structure) regulatory mechanisms in unicellular cyanobacteria. This article provides an insight into the heat shock response (HSR); its organisation, and eco-physiological regulation and role of molecular chaperones, in unicellular and filamentous nitrogen-fixing cyanobacterial strains.
