Bacillus cereus spores and toxins - The potential role of biofilms.

Food microbiology, 2020
Bacillus cereus is a well-known foodborne pathogen capable of causing two types of gastrointestinal diseases, diarrhoea and emesis. It is of particular concern for the food industry causing food safety issues, due to the formation of spores, biofilms and

Why be serious about emetic Bacillus cereus: Cereulide production and industrial challenges.

Food microbiology, 2020
Cereulide, a potent toxin produced by Bacillus cereus, is a small, highly heat- and acid-resistant depsipeptide toxin, which confronts food industry with several challenges. Due to the ubiquitous presence of B.

Lead bioaccumulation mediated by Bacillus cereus BPS-9 from an industrial waste contaminated site encoding heavy metal resistant genes and their transporters.

Journal of Hazardous Materials, 2020
This study explores the soil microorganisms for their Lead bioremediation capability. The MIC values of the six Lead resistant bacteria were evaluated, and the AAS studies of these isolates estimated their Lead accumulation percentage. The results showed

Inactivation kinetics of Bacillus cereus spores by Plasma activated water (PAW).

Food Research International, 2020
In recent years, plasma activated water has attracted more attention as a new disinfectant. The purpose of this study was to explore impact of variation of different treatment conditions on the inactivation kinetics of Bacillus cereus spores by PAW.

Amelioration of Cd-induced bioaccumulation, oxidative stress and intestinal microbiota by Bacillus cereus in Carassius auratus gibelio.

Chemosphere, 2019
The heavy metal cadmium (Cd) is a hazardous pollutant known to exert various toxic effects and other sublethal to lethal effects on aquatic organisms, and can be commonly found in environment.

Modelling Bacillus cereus growth

International Journal of Food Microbiology, 1997
The aim of this study was to model the growth, in a model system, of toxigenic strains of Bacillus cereus as a function of temperature, pH and water activity. Optical density (OD) values were transformed into numbers of colony-forming units (CFU) by the use of a 'calibrating' relation.

Extracellular electron transfer of Bacillus cereus biofilm and its effect on the corrosion behaviour of 316L stainless steel.

Colloids and Surfaces B: Biointerfaces, 2019
Here, a heterogeneous Bacillus cereus (B. cereus) biofilm on the surface of 316 L stainless steel (SS) was observed. With electrochemical measurement and surface analysis, it was found that B.

Ribonuclease of Bacillus cereus

Nature, 1962
PRELIMINARY work on the biochemical effects induced by pancreatic ribonuclease on Bacillus cereus cells led us to investigate the normal level of RNase at different growth stages. It is a well-established fact that bacterial cells form intra- as well as extra-cellular ribonucleases, but the information concerning their role is meagre1–3.

Posttraumatic Bacillus cereus Endophthalmitis

Archives of Ophthalmology, 1987
We encountered a patient who developed Bacillus cereus endophthalmitis following trauma. Early therapy, which included intravitreal clindamycin phosphate and gentamicin sulfate, resulted in a visual acuity of 20/60. A five-year retrospective review of all cases of endophthalmitis following trauma reported at our institution revealed Bacillus as the ...
